Never seen an engine fail from too many oil changes. Oil is cheap engines are not. 5000 miles. Like the Toyota guy at the car care nut says. He has some good videos on it.
This is 4th grade level thinking and it embodies the laziness and ignorance that millions of car owners have, much to the delight of those who profit from needless oil changes (dealers, service shops). Meanwhile, oil companies spend millions in research & development and modern synthetic oils enable our modern world. I have been sending off used oil samples for lab analysis for 10+ years and have LEARNED that the ideal time to change your oil is (graphically speaking, as on charted lines), when the TBN line crosses the TAN line, and, of course, this WILL be different for every engine, driving conditions, and brand, type, grade of oil used, but, generally speaking, on a non-turbocharged engine that is NOT GDI and on synthetic oil (mine), the test lab is not interested in even seeing an initial sample until 7500 miles. I generally go 12-15K between oil changes and have been doing this for several years. Lest anyone wish to lecture me on how I am "destroying" my engines, you can argue with the test lab. What HAS ruined my cars is not mechanical neglect of any kind, I've gone over 250K with engines, but the Little Old Lady From Pasadena is out there, and anyone's car, even if you change you oil daily, the longer it is on the road, the greater your chances of an accident. Other drivers destroy my cars.
I have a 1984 Toyota van with a 22r 4cyl engine. Bought it new I change the oil with full synthetic 10-w30 every 5 thousand miles. It now has 475,000 miles on it and runs great .no major repairs. It's now my camper.
I bought my car new in 2015. I got it's first oil change at *200* miles. I got it's second oil change at *1000* miles. Every oil change after that was at *3000* miles. It now has 130k miles on it and it still sounds brand new. It burns zero oil between changes and there's zero leaks from any seals. I started doing my own changes when it was out of warranty. Since we have harsh winters here, I put in that mobile synthetic that's supposed to last 15k or 20k miles. That I will change after 5k miles or when it's first nice enough outside to change it comfortably. CHANGE YOUR OIL
yea been doing my own maintenance too not sure about the every 6 months thing let's say the car only hits 3k before 6 th month then should you change the oil? I suppose yes how about the oil fliter ?
I send my oil in to Blackstone labs. It took me 3 years to put 5,000 miles on my 700 hp Shelby gt500. They told me to go 7,000 miles next time even if it takes 5 years. They said the oil doesn't break down with age, go longer!
Ron, even though you don’t drive it that many miles, you still may wanna take it out on the hwy every few weeks to burn off some of the condensation that may built up in the fuel system.
This is exactly the information I have been trying to ascertain and nobody has been able to give me a clear answer.Does oil break down with age?? Nope! I have the same thing with my truck that I don't put many miles on in a year.
@carlovanrijk4039 Yep, hit the pedal to the metal on your car on the freeway and get it to about 90mph, then slow it down and look out for the cops? Do it when traffic is slow and not congested.
Many people don't realise the number one reason why engine oil degrade and loosing it's viscosity is because of fuel dilution the engine oil because the fuel they are using doesn have enough or in America maybe 0% detergent in it. So what happen is your fuel injections system became dirty and it won't atomize the fuel enough causing for of thick liquid form of fuel and the engine will not able to burn the fuel causing it slips into the piston rings area into your engine oil. Another reason why the fuel turns bad loosing it's viscosity is moisture and lastly if you always run hard heavy load on you engine the polymer additive that responsible to keep your viscosity into certain degree will break the polymer molecules and you will loose your viscosity and causing futher wear. Remember the worse thing you do to your engine oil is to keep idle for a very long period of time and stuck in heavy traffic for long hours everyday counts as well beside your mileage. Is better to use cheap good engine oil and change it often rather buying expensive engine oil but dragging your oil interval at insanely long. So if you know how to change it yourself you save money from labour charges and change it when ever you feel the engine is no longer feels good or smooth when driving or if you really can't tell the difference change it every 5000km the max. Like me I stuck in heavy traffic almost everyday, I normally change the oil every 3500km or sometimes 5000km when I really have no time to it. I am using Shell Rimula R6 LM 10W40 oil because is a very good and cheap engine oil for my gasoline engine. This engine oil is meant for diesel engine but so far at 187,000km the engine is still smooth and my catalytic converter has 0% issues, I will say it is way better than Shell Hilux Ultra gasoline engine oil but way way cheaper. Is only $102 USD for 20 liters of engine oil here in Malaysia. Don't waste your money on expensive Pennzoil because it is Shell, Shell bought it in the year 2002.
Just starting to watch the replay of this premier now. I 100% change my own oil (and filter) for both of my cars. My BMW with the N54 twin turbo is drive very little, so gets an oil change annually regardless of miles. My Hyundai Elantra is my daily driver, with lots of short trips around town, so I change the oil at ~3K-5K miles religiously. I use top quality synthetic oil in both engines, the BMW getting a more premium brand.
I have a friend who changes his oil in an RS Audi at 6000 and then puts his used oil in the family car where it runs for another 6000 miles until it's due for a swap again. Thankfully they do take similar grades of oil.
@@torquecars So they can afford an Audi RS, but not new oil for the family car?? Penny Wise and Dollar Foolish. That's just utterly ridiculous honestly.
Every 4,000 on all my cars with full synthetic and an OEM filter. My wife takes a lot of short trips on her Mercedes . Which is hard on an engine .So sometimes I'll change it at 3,000.
I change oil based on oil analysis. I start by having the oil analyzed at the manufacturers specified interval. I adjust the interval according to the analysis. In my 20-year experience of having oil analyzed on a series of vehicles from passenger cars, light trucks and farm equipment to help determine the OCI, in my particular operational situation, factory intervals are overly conservative in most cases. Especially as regards time. I extend them out generally, though one diesel tractor demanded a shorter hour interval due to soot... but that that tractor has 9,000 hours on the clock. I have seen no significant lubricant degradation out to three years. Indications are they could go more but I drew the line there. The cars and light trucks are now at 10K intervals and three years. The tractors are at 100 hours or three years. One tractor usually reaches 100 hours within a year and some, the other usually makes it to three years. I know of one tractor that sat 30 years in a dry climate and when the oil was analyzed, it was considered still suitable for use. Oil doesn't wear a wristwatch, nor can it read a calendar... but it does respond to environmental conditions and will degrade rather more quickly in damp storage or places where there are wide variances in temperature (condensation). Bottom line, it's all about the operation situation. And analysis can lead you to the right spot. FYI, I only use analysis to determine the interval and as long as my operational situation doesn't change, further tests are not done... except occasionally. I have owned one truck since 1987 (bought nearly new w7K miles) and a car since 2000. The tractors 20+ years. Have not have a single failure on anything due to my OCIs.
Yes, I want to see more time based test results from actual labs vs people just saying it goes bad. I don't think I've ever changed oil in six months or less. It's usually mileage or condition of the oil that determines when I change it, not time and I'm glad to see some analysis that shows that even after several years, oil can still be fine to use.
That is not many miles at all so this seems very sensible to me. As said though it depends on how a person drives and the type of car it is. What sort of engine is this in?
@@torquecarsI’m just the opposite. My place of work is an hour away. 120 miles round trip. I may do 25K miles per year so I change my oil 4X per year at just over 6000 miles per oil change interval. I could probably go 8000 miles at 3X per year, but I like to keep the oil as clean as possible.
Two turbos, ouch! What was that in? I found out that a local mechanic was using mineral oil instead of synthetic, the viscosity was correct and he didn't understand why people were getting so upset.
Is this one of the newer direct injected turbos? I've been seeing a lot about how they use a lot of oil, and I can't help but wonder if not keeping oil topped up is a factor for you.
I change my 1986 porsche 928S every 2 years with 8 liter of 20w50 non synthetic oil and drive less than 3000 miles a year and live in Southern California. My car has close to 200000 miles and does not burn oil and still running fine. I do my own oil change. Oil change should be done on engine operating hours. Short trip does require shorter intervals because engine does not reach normal operating temperature to burn off moisture.
As a retired person, who only drives their older diesel vehicle about 20km once or twice a week, I have been relying on annual oil changes thinking that would be sufficient. After watching your video, I understand how oil degrades over time and I will be more diligent and have the oil changes done every six months from now on.
IF you get your oil up to full op temps on regular basis you should have no worries going annual on change intervals with such low miles, oil analysis would let confirm this.
Just use full synthetic and don't worry about it. Changing it once every 18 months is perfectly fine if the engine is in good working condition and it is driven warm most of the time.
I Have a 2010 Toyota Camry with a 2.5L 4 cylinder. I drive about 300 miles a week to work all highway miles 60 to 75 mph everyday. I use a full synthetic oil 0w-20. I have 250,000 miles plus on my engine. I change my oil every 5,000 miles. No issues and my engine doesn't burn no oil!
I really appreciate your videos! They aren't flashy or pushy or overly edited, but filled with great detailed information. Keep it up, new subscriber here!
Look forward to watching the video for sure but before I watch it - IMO - it's so inexpensive to buy 5L of oil that meets the spec (for 1.8T Beetle) that I do it every ~4 or 5k miles and replace the filter every second change. Will be interesting to see your results and other people's opinions.
It can be expensive but there are online suppliers out there, one I use is www.opieoils.co.uk and I tend to buy in bulk so it lasts me around 4 changes and in the long run I save some money. Buying oil is always cheaper than repairing an engine though, unless you change oil every month! lol
Absolutely agree many people don’t understand that it’s not just the mileage that matters in oil but like you mentioned other stuff like fuel dilution especially in GDI engines the dirt in the oil the oxidation
Have hung out on BITOG for years (Bob Is The Oil Guy). Most of the Blackstone test results you see there for good full synthetics don't even start seeing degradation of the additive packages until around the 8000-mile mark (US). I change mine at 7500 because that often divides into other service intervals nice and evenly, essentially maintaining 'like-new' performance of the oil.
@@torquecarsthis is primo information concerning the life of engine oil and the recommended oil change intervals. The points you cover make absolute sense as to how oil degrades over time due to heat, contamination, blow-by, and etc. As I DIY my own oil changes, I am more focused on the intervals. I drive mostly hwy miles to work and back so my interval could be 6700 miles in a 3 month period. Blackstone Lab analysis states that the oil could conceivably reach 10K miles before needing to change, but I’ll leave it at 6700 miles for (hopefully) long-term reliability. (2016 Honda Civic). Although because winter weather is cold, I may have to stretch that interval to 8K miles. Not optimum, but doable.
additive degredation is one part of it, but what about liquid characteristics? fluid viscosity, friction & wear testing (how much lubrication does the oil provide between 2 rubbing metal parts & how much material is lost during a friction test)
But really, who cares if u are wasting by changing too often. Oil is the heartbeat of the engine. I change mine 6mos/5,000 miles. On my 2019 Prius. Yes, I KNOW it doesnt run as often but hot/cold/gasoline/condensation/direct injection? Pay now, or pay later. Your analysis if 6mos/8,000 miles is decent, maybe 6-7,000 the most. Great video! 👍🇺🇸 PS. I do my own oil changes and I drain it in LENGTH, & even TILT raising it to get it all out. It's so clean, u have trouble seeing it on the dipstick. My old 97 Camry had 265,000 miles & oil remained clean until 1,000 miles. I changed that @ 3,000 miles & ran like a top!
Your videos are the best! I’ve binge watched loads now, can’t get enough of them so well presented, produced and easy to watch and understand! Thank you keep up the good work!
On my Ford Taurus with a 3.0 V6 engine, I only used conventional oil in it. I was leery about using synthetic in it..I changed the conventional oil on it every 5,000 miles, not 3,000 miles as recommended. The conventional oil was dirty at 5,000 miles. That car lasted up to 160,000 miles until the transmission died on me. It wasn't wise to get a used transmission with only a 90 day warranty, so I got rid of it. The car I drive now recommends synthetic only. I checked my oil at 4500 miles, and was amazed how clean it was at the same mileage compared to conventional oil. The difference like night and day? I will change my synthetic oil at 7,000 miles regardless of how clean it looks. Engines are expensive, oil and filters are not. .
Since the last change installed timer which counts how much time the engine works, will change oil once it reach 250hrs of work (warmup, idling, congestions, city/hway) all will count as a work time will see, currently expecting some 7+- k km once it reach 250hrs. in terms of calendar it'll be more than a year
Our two cars : 2008 Mini Cooper D . 108,000 miles previously fsh changed every year and twice in 1 or 2 years.Fully synthetic. 2017 Citroen Cactus 1.2 puretech 82 (non turbo!) Changed 3 times since May 2022 . This puretech has a WET timing belt , hence the need for clean oil . Fully synthetic only allowed on this one , currently on 56,000 miles.
Interesting and informative video. I know little about this, but just from a logical perspective I'm always a little skeptical of the information. Because IMO attitudes about oil changing are often akin to cleanliness. Purists and the absolutists abound. For example, you'll find people that flush automatic transmissions rather than do a pan/filter job, even though manufacturers generally don't recommend it and it is known to cause problems, because some people just can't handle the fact that not all the oil will be drained from the transmission. Likewise, in these recommendations you seldom see anyone refer to how much oil is used between changes. Many cars use a quart every 2k miles or so, and always have and always will. My car has always used a quart every 1.5 to 2k miles (which is normal for these notoriously long lasting engines as far as I know), and so after 7k miles or more it still looks almost new and smells great. Because it is mostly newer oil. I certainly don't change it every year if I'm under 8k miles. Under the mild conditions under which I drive, I commonly go 2 or 3 years. Here is where people will stridently claim oil turnover makes no difference, because without changing it you're not removing 100% of the old oil. But of course, you can never remove 100% of the oil and probably 1/2 quart gets left behind during oil changes depending on the oil pan design. So I can't help but wonder if the real issue at this point isn't wear of beanings, rings, and camshafts that should determine oil change intervals as much as whether an engine has a turbo, direct injection, VVT, and possibly long & complex timing chain paths that many dual overhead camshaft engines now have. My car isn't new and has none of those features. VVT in particular I am told, in which the oil serves to move hydraulic actuators, is very sensitive to additive levels.
This is one of the most polarizing subjects I have covered, with passionate debates on both sides. These new technologies certainly hammer the oil and is probably the reason why many have really short change intervals.
I Was talking about my 84 Suburu with 250.000 miles with no oil drains on RUclips. A Caterpillar lab manager sent me a sample kit. He said the oil looks for that many miles. He found some caramelization. He recommended I change the Frantz oil cleaner every 6.000 miles and add a quart of Mobil 1 instead of every 12.000 miles. The Pontiac Torrent uses a Australian Jackmaster Classic oil cleaner and Walmart synthetic oil called Super Tech. I do 6.000 miles now. I started in 1963 with a Frantz oil cleaner and Delo 30 W. The Motor Guard oil cleaner on the old Ford 390 is over 50 years old. I still use a few Gulf Coast filters. I like the top loaders. I have a flat head Ford V8 canister filter on the old diesel tractor. It has half a roll of Viva towels in it. Cant get good cartridges for the old canisters these days. I am a filter guy. I dont run on dirty motor oil. I drive mostly highway.
I just bought a Trax 2024 - 3 cylinder 1.2L turbo. I'm getting the oil changed at around 800 miles, then at 3000, then follow a 6 month/4-5k mile schedule.
If your fuel economy is 60% to that of mfg then do it at 60% mileage then what is mentioned in the service book. Stick to fuel economy percentage of yours compared to manufacturer declared. You can still take 20% leverage on that. Manufacturers will assume 80% highway run 20% city, same as to show average fuel economy.
Hi, agree to all said.Myself i change oil at 25000km without a worry. I am using "polytron mtc". have done oil analisis every 2nd oil change. 43+000km on my dash, jetta 2003 alh,manual.
@torquecars opposite, I find it more responsive. I am not the only one noticing this. We're about 300+ cars owners. I have few oil lab results. Let me know if you want it
Interesting, but probably most viewers would like to know specifics. Whenever I visit an oil change facility, they all tend to push you into shorter intervals like 4 to 5 thousand kilometres. I use synthetic oil in my Toyota Corolla 1.3 and change the oil and filter after 10,000 km.
I changed the oil every 6 months in our Audi A3 in the last 10 years and I do it with our vw golf estate too. Total cost £40 (oil+filter) half the price garages do it in the UK
I wait for the Oil offers. Mine is around £25 total to change. I don't use really expensive oil mostly Mannol Fully synthetic 5W-30 which is cheap. And a decent Filter. I believe you can use a lower cost oil as long as it's changed more frequent. 4000 miles or every 6 months.
People can keep debating engine oil change interval for eternity; nothing can destroy the engine faster with insufficient oil level in the sump. So please do check the dipstick at every fuel stop.
I do not do high mileages, so I do my changes at 10,000 kms or two years, whichever comes first. I have tested the oil since buying the car and it always comes back with comments saying that it is fine & not showing signs of wear or changes compared to previous tests. I do my own oil changes.
An oil analysis is the best way to clarify how often you should change your oil. Normally the manufacturers recommendations are pretty accurate (10,000 km is pretty accurate for our Toyota Yaris)... although I wonder about some of the really long oil changes. However, changing oil every 6 or 12 months is a waste of time. The oil doesn't go off just sitting there. Any oil analysis will tell you that. Change oil based on km travelled. 🙂
A synthetic oil lasts longer than a mineral oil: A semi synthetic is almost as good as a full synthetic. If you want to extend the oil lifespan a bit longer try a high efficiency oil filter (removes more particles), foam air filter (less dirt) or bond a lubricant to the metal (XcelPlus). All 3 of those will also reduce wear in an engine sometimes dramatically i.e. Up to ~90 %. 🙂
BTW: I've noticed that cars that have 20,000 km oil changes have twice as much oil as cars that do 10,000 km oil changes. Conversely motorbikes that change oil every 5,000 km have about half as much oil as cars doing 10,000 km changes. It makes sense that the oil would last twice as long if there's twice as much of it. So perhaps the longer oil changes aren't as unrealistic as people think? For some reason nobody ever mentions the volume of oil being used when having these discussions. N.B. An oil analysis would soon clarify this issue. :-)
Unless you run a huge fleet of vehicles; the cost of oil and an engine filter is minimal, especially if you service it yourself. Car manufacturers are in the literal business of making sales. They do this by showing decreased servicing cost from longer service intervals. They frankly care only that the car makes it past the warranty with some buffer. If it is worn out, they know your going to buy a new one. My advice is service the car with competent people that aren't likely to induce maintenance faults. For me that is myself with cars.
Oil is cheap engines are not between 2000 to 3000 miles I do it myself and use Mobil 1 or Pensoil ULTRA You are right oil gets dirty.. The Head engineer for Nissan on Automotive Press says change it at 2000
I change mine every 5k miles or 6 months absolute max. Usually 3k-4k miles. Synthetic, new filter every time. Is that excessive? Not for me it's not. For others, it might be for whatever reason. If you drive hundreds of miles a day, 5k-7k mile oil changes would make more sense. This is not a settled argument and never will be because the answer is catered to individuals and their circumstances. I will say this though- too infrequent oil changes can damage your engine, while frequent oil changes cannot. That is an undisputed fact.
I used to change oil in my 77 cutlass supreme 350 4 barrel every time it got dark. Now 5 to 8 thousand with 3.5 ecoboost ecoboost, Godzilla and V10. Penzoil Ultra Platinum 5w30.
When discussing the topic of oil changes, it is usually forgotten that the engine lasts longer than the car itself. It also seems to be forgotten that engines very rarely break down due to incorrect oil change intervals. Just do what the manufacturer recommends and you'll be on the safe side. If you have too much money, change the oil as often as you want, it will only calm your nerves.
I do oil changes every 6 months / 7,500km, whichever is the earliest on my 07 Merc v6 Diesel. I change the oil filter every second service. A good rule for changing oil in diesels is to put oil from the dipstick onto your finger, and then wipe it off your finger. If it cleans up perfectly, then the oil is still clean. if it leaves black stain in your fingerprints, then it needs to be changed. when oil stains stick to your fingerprint, it means the oil is saturated with soot and is not cleaning as effectively anymore. Manufacturers recommend 15,000km or even 20,000km these days, which is ridiculous.
The reason why manufacturers recommend longer intervals is so they can advertise a lower running cost of the car as a whole. Also, if someone changes oil at 15,000km or 7,500km, they will not notice any difference in the car's performance in the first 10 years of the car's life. These differences start appearing after 10 years or 200,000km, which is well beyond the warranty period of the vehicle. This means there is no incentive for the vehicle manufacturer to make oil change intervals more frequent.
I change my oil when it gets dirty. For my daily commuter vehicle that is about 1500-2000 miles. In my opinion mileage is a terrible indicator of when to do maintenance. Engine hours is the best way to schedule maintenance. For an example some people live in the middle of nowhere. They might get on the road and drive at 70+ mph all the way to work and back. This person will have 7,000 or more miles in 100 engine hours. I’m on the other extreme I drive in an area that had horrific traffic. I don’t get over 20 mph on my commute (the average speed is probably about 10 mph) and sit stopped on the highway for several hours each day. In 100 engine hours I’m lucky to get 1000 miles! Assuming your going to change your oil at 250 hours ( I prefer 100 hour changes but I’m very anal about my equipment) this can work out to 15,000 miles for someone who lives in the middle of nowhere or 2,500 miles for someone who lives in a congested area. Car manufacturers are going off a 250 hour service and an average speed of 40 mph when they say change the oil at 10,000 miles. I’m willing to bet most of us won’t even come close to an average speed of 40 mph if we are commuting to work! Assuming an average speed of 30 and a much kinder 100 hour service you get 3,000 miles. My advice is change your oil at 3,000 miles or 100 hours if you have an hour meter. I am religious about 100 hour oil changes on the gensets at work and they have been lasting over 40,000 hours! That’s roughly double what they lasted with 250 hour service!
I must add car manufacturers know that mileage is a terrible way to judge oil life. This is why they have a time interval. Your oil doesn’t go bad from sitting (at least not for a few months or a year) this time interval is an attempt to keep you from putting a shitload of hours on your oil if you drive in heavy traffic. Unfortunately this is also a guess that assumes you only drive a certain number of miles/hours a year. Some vehicles that have a oil life monitor actually count engine hours. This is a much better system but unfortunately it’s usually based on a 250 hour service interval. My advice is to change your oil at 50 or 60 percent oil life if you have said system. Beware some of these systems just count mileage and are truly useless so keep that in mind. The easiest thing and what I do is change when the color of the oil on the stick becomes a darker color. It might not look dirty but when you drain it it will be black. Unfortunately I can’t show you this shade but I know what oil with 100-150 hours on it looks like from decades of experience. Investing in an hour meter is your best bet. These hour meters are dirt cheap and very easy to install. A simple oil pressure switch can be used to power them when the engine is running.
I used amsoil ss in my honda 1.5L N/A engine for as long as 7k km (~4.4k miles) in 9 months usage period. after doing oil analysis, I was shocked by the oxidation level (at 59). while most of the wear metal numbers were low, the lead (Pb) was of 10 ppm. Although 30 ppm is usually the upper limit of Pb but I wasn't satisfied with the result. I'm switching to 6 months duration regardless the mileage to improve oxidation, but it means I have to use cheaper oil because amsoil cost just doesn't justify. the car is used in tropical country where outside temp is quite hot.
I dont drain oil. But I drive mostly highway I dont have a turbo. I use depth bypass filters.I change the filters and add a quart of new synthetic oil every 6.000 miles. In the 60s I used depth bypass filters and Delo 30 W and changed the depth bypass filter every 2.000 miles. One time I had to drain the oil and change a head gasket but other than that I havent had engine problems. I dont go over 250.000 miles on a car. There several filters that clean oil. The Pontiac has a Australian Jackmaster Classic. My oldest filter is a over 50 year old Motor Guard on the old Ford truck..
I have 2.0 Tdi PD 103kW BKD changing oil every 6 month or 6200 miles. Also change the oil and air filter. Once per year change the fuel and the cabin filter. I do it myself, I dont have any problem with my engine. I never sent the oil to the laboratory.
Do myself since dealerships overfill and sometimes don't change filter. Always change synthetic blend/ full synthetic and filter every 5000 miles or once per year whichever comes first. Oil is cheap, pistons & rings are expensive. 🙂
Depends on driving conditions.i just look at it and change when it gets to dirty.my 95 vette i drive mostly highway but its hard driving.usually around 3000 miles mobil 1 pure synthetic.my 99 infiniti might get away with close to 5000 but again i CHECK IT REGULARLY! Also i have a 06 mdx which i take fishing 40 miles total trip but i idle the car around 3 hours straight because i hate heat cold and bugs.so thè mileage would be low but oil is taking a beating so like i said driving conditions and check it regularly!
I got a 2024 Chevy Trailblazer RS I change my first oil at 800 me the second one is being done at 2000 and then every 3,000 after for the life of the car
Hi! My story. I use Mobil 1 5W-30 EO with my VW Golf Mk2 (1983 year) with secondary engine of 1992 (year about). I drive with this oil very long time and engine stops working because of lost viscosity. If I calculate properly - I add 2Liters of oil every year, because of piston rings wear. That means - I partially "change" oil with new and I change oil filter every 5 years... Total time was about 15 years in this "conditions". My engine (I was lucky) stops inside garage... and I was able to do job inside. I drain oil - no viscosity - like liquid sour cream, remove oil pan, check oil pump, inspect piston "legs". Everything was in very good condition. Than I remove crankshaft and find 1 stuck`ed valve, but it was not bent!!! Just stuck`ed. I reassemble everything back, add 5W-40 Mobil engine oil, than I start engine which was very noisy, remove deposits on the valves with Carburetor Cleaner + Water and my VW Golf is back on the road! P.S. Yes - please change your cars engine oil! Some recommend after 8000km, some after 5000km... maybe 12000km is last chance? Be Happy!
For my daily driver, 4runner, 5k or 6 months. Never hit 6 months though. For my 1991 Nissan 300zx twin turbo, 3k or 6 months. I only put 2-3k a year though and mostly drive in spring summer months. I do full oil and filter change in spring, if I have not hit 3k miles will just do oil drain and fill in fall
Years ago BMW ran a car continuously for 1,000,000 miles stopping only for refuelling and scheduled oil changes using Mobil 1 0W 30. After the car reached 1,000,000 miles the engine was completely stripped and all parts were found to be within manufacturing tolerances.
Old engines were better built than modern ones. Manufacturers later realised that long lasting engines were not a good business model. Modern engines now contain lots of plastic components which wears out faster and need frequent replacement, again, a good business model. Therefore, regular engine oil changes make a lot of sense, especially if you plan to keep the vehicle for longer.
I have a ram 2020 2500 power wagon I change my oil every 15,000 miles and I use the cheapest oil possible and the cheapest oil filter my old filter I’ll let it go to 30,000 miles I have 43,459 miles everything‘s going well I think I can get 350 to 400,000 miles out of it if I continue to stay on top of it and do my oil changes regularly
DIY oil change is quite easy and inexpensive. Here in the US full syn is still about $20 including filter at Walmart Supertech. I do often at 5K-7K miles depending on the type of miles I drive. I may go 8K if it is nearly all uncongested freeway miles. 3K even with full syn if mostly city or congested freeway miles, creeping 15 miles in 45 minutes type driving.
It depends much on the oil, driving, and sump capacity - if I was using a cheap mineral oil and short distances on an ordinary car maybe 3,000 miles - I use Profleet synthetic, fairly long haul, and an oversized sump and filter so 6,000 miles +
I believe 6 months, or 5000 miles is a good idea even if oil still lubricates well i thing you will get sludge buildup if you go too long, have stretched it out to 10 months when only driven 2000 miles but i found one car had foamy water oil buildup under cap from being only driven 5 minutes to work by kids.
I gave up allowing the oil to get dirty and oil changes in 1963. I use filters that clean oil and I try not to start the engine unless I plan on heating up the oil. Shutting off a cold engine is bad for engines. You want the PCV to do its job.
If I had a son I would spend a minute teaching him how to change the filter element in the Australian Jackmaster Classic bypass filter. A lot better than allowing the oil to get contaminated and draining it. We dont do dirty oil in my family.
50,000Km here on amsoil with regular oil analyst every 5000km if the oil is still good why change it now I'm trying Hotshots black diamond outlaw oil 15w40 lets see how long this can go.
i Changed oil every 3 months/3000 miles. My car has almost hit 500,000 miles. Changes your oil 10k, 12k, or 15k than you might 250,000 out of your engine.
You certainly are taking no chances, conservative but effective. Assume you are same on air filtration and coolant? Bet the internals on that engine are clean clean clean.
It took me about 20 years to put 250.000 miles on a 84 Subaru with no oil drains using a Frantz oil cleaner and Mobil 1 15 50. I gave up the dirty oil and oil changes in 1963. My Pontiac has a Australian Jackmaster Classic. I like the top loaders.
I have a 2007 honda odyssey and always change my oil 5k less w synthetic. When i had to redo my bent valves, i was so surprise how clean my engine was. Show if u take care of ur car, the engine can last a long time. Oil is cheap, engine and labor expensive.
j.t., I work at a Honda manufacturing site (we build the CR-V’s and Civic’s). I’m with you on the more-frequent oil change intervals. As my family mostly drive Hondas and Toyotas, I’m a stickler when it comes to regular maintenance (I do the maintenance myself) - it keeps our vehicles from going into the shop.
My SUV doesn't get driven a lot so it gets annual oil changes, which is what the manufacturer recommends if it doesn't do 10,000km a year. But my Triumph motorcycle is what I commute to work on and, while the manufacturer recommends a 10,000km oil change interval, I simply do not trust the 3.2 litres of Castrol Power1 Ultimate synthetic oil in the sump to last that long in our hot tropical climate without succumbing to evaporative losses. And my bike gets revved twice as much as my SUV. So I change the oil at half the manufacturer's recommended interval.
OIL is relatively cheap……twice a year. UNLESS your oil change cost $245.00 (like my neighbor’s Porsche) then I would change it every 8 months… I am 73 yrs old, with spine problems (don’t need to be getting under a car) My local Toyota Dealer charges $79.00 for full synthetic oil & filter plus a full inspection. Pretty good deal for me.
I am in the UK and my partners 2016 Audi A1 1.6 TDCI manufacturer users manual states 10k miles or 1 year for oil 5w30 fully synthetic. I has 52k miles on it. Why should I change it less than this interval? It is expensive in the UK to get a fully synthetic oil/filter change. Cheapest last time was £120.
Synthetic is loads better, mineral oils tend to break down when they take a beating inside an engine. I guess this is why most turbos require fully synthetic. I have known some mineral oils to be labelled as synthetic in some regions which doesn't make a lot of sense to me.
I use high grade 0W-30 for Honda diesel, I drove in 2 months what the previous owner did his last year of ownership LOL. I do many trips 400km+ daily. Filter and oil sets met back 55 Euro, every 10000km, DIY job. 10 minutes. Never skip on oil change.Interval depends on type of drives and content of the oil pan. Honda has 5.9L on 2.2 4 cyl 🛢
I have 232k uk miles on one of my engines and i change the oil every 4 months between 7000-9000 miles... seems fine...do not have a clue in uk were you could send a sample of oil to a lab so a enlightment would be apreciated.😅
Last time I tried to post links here the post got deleted, when I did a search on Bing I found quite a few "uk oil analysis labs" millers, the oil lab, oilsamplingcouk and my personal fave is Ravenol which is pretty low priced but didn't include oil fuel dilution tests IIRC.
Look it is the manufacturers that want your service when things go south on your engine. So change it as you wish. I do it every 3 thousand miles for my satisfaction and peace of mind.
Between 2000 and 5000 miles here on both cars depending on usage, one turbocharged Subaru, the other a turboDiesel Prado. I try to find Diesel specific oil for the Diesel engine for the hopefully higher detergent content. Have never gone long intervals in any of my cars because i do all my own work and bought in bulk packs of 20 litres oil is cheap, been decades since i had an engine or transmssion issue, trans get serviced too, any sealed for life cobblers there is unceremoniously ignored. What the hell is sealed for life or long life when a car is concerned, anyway, most makers couldn't give a toss once the warranty has expired so for too many makers long life or sealed for life means 3 years then if it gos bang tough, you don't find Toyota who offer 10 years warranty if you get the car serviced by them recommending 24k miles oil changes, wonder why? Just as important for engine (and turbo) long life is warming the engine before driving it hard and allowing turbocharged engines to warm down for a minute or more idling gently after driving to allow the turbo to cool down, at least one minute more if you've been driving hard. They say there is no need for this any more because apparently water cooling carries on after shutdown these days, well i've covered getting on for 4 million miles now in turbocharged vehicles, have always allowed them to warm and cool, and am yet to have a turbo failure, my method aint broke and see no reason to fix it.
For GDI and turbo charged engines, every 3000 miles. For naturally aspirated and port injection engines, every 5000 miles. Just follow this and your engine will cross 600,000 operating hours without any problems. With every oil change; oil filter replacement is mandatory.
I don't think so, but I've only really got UK experiences. As far as I know the Service schedules are the same in each region. Sometimes oil specs and fluid specs are different.
Extreme hot like Australia or cold Canada or even very hilly places like Nepal would make a big difference compared to a very flat place like Holland . And if you live near me the potholes in the road will take a few years off your car as well 😉
I use to do it in the 1960s every 3000 miles. By the 1980s, the additives in the oil made it superior. So, 8000 miles was recommended. Now, go onto RUclips and watch the tests. 10,000 miles is now the target here. However, dealers want your money, so they still say to change it every 3000 miles.
I've not heard of any oil manufacturer now recommending 3000 miles, though car manufacturers try to sell the idea of long service intervals for fleet buyers and reduced running costs to private buyers - they are never a good idea for any engine optimum longevity. It isn't just that oil technology has improved with both additives and synthetics but machining tolerances too and material durability have vastly improved. Engine rebuilds outside of exotic performance cars are rarely heard of now, whereas it was very common when I first started driving. Most smaller engines here in the UK, in the 50's and 60s would be lucky to last 100K, even with 3K oil servicing, even the legendary XK engine. Nowadays even petrol engines can last far longer and diesels can can cover huge mileages, but rarely ever with long service intervals. The price of an oil and filter change is less than a full tank of fuel in most cars these days, at least here and so 6 months/6K is not a huge price to pay, for often incredible engine life.
In the 60s I didnt drain oil in the Rambler American. Every 2000 miles I changed the Frantz oil cleaner and added a quart of Standard RPM Delo 30W. Delo was beautiful when clean. I still dont change the oil in the Pontiac but I change the Australian Jackmaster Classic every 6000 miles and add a quart of Walmart synthetic 10 30 oil. The oil is clear. Im told I wont get to oil change heaven.

![🚫10 Driving Habits That KILL Your Car 💥[Warning]](/img/tr.png)
From Puerto Rico With Love: Oil change every 5,000k/6-month intervals. "Oil is cheap, engines are expensive."---Scotty Kilmer.
Never seen an engine fail from too many oil changes. Oil is cheap engines are not. 5000 miles. Like the Toyota guy at the car care nut says. He has some good videos on it.
Never heard of engine from 10k synthetic oil changes . Stop wasting people's money.
This is 4th grade level thinking and it embodies the laziness and ignorance that millions of car owners have, much to the delight of those who profit from needless oil changes (dealers, service shops). Meanwhile, oil companies spend millions in research & development and modern synthetic oils enable our modern world. I have been sending off used oil samples for lab analysis for 10+ years and have LEARNED that the ideal time to change your oil is (graphically speaking, as on charted lines), when the TBN line crosses the TAN line, and, of course, this WILL be different for every engine, driving conditions, and brand, type, grade of oil used, but, generally speaking, on a non-turbocharged engine that is NOT GDI and on synthetic oil (mine), the test lab is not interested in even seeing an initial sample until 7500 miles. I generally go 12-15K between oil changes and have been doing this for several years. Lest anyone wish to lecture me on how I am "destroying" my engines, you can argue with the test lab. What HAS ruined my cars is not mechanical neglect of any kind, I've gone over 250K with engines, but the Little Old Lady From Pasadena is out there, and anyone's car, even if you change you oil daily, the longer it is on the road, the greater your chances of an accident. Other drivers destroy my cars.

it is still unnecessary money thrown away if done too often, like i could do it every day but whats the point spending 1000€ every month on oil?
I have a 1984 Toyota van with a 22r 4cyl engine. Bought it new I change the oil with full synthetic 10-w30 every 5 thousand miles. It now has 475,000 miles on it and runs great .no major repairs. It's now my camper.
That old 22R was literally the best motor ever built . And they were even better when they became "injected " .
How often have you changed your tranmission fluid ?
I bought my car new in 2015. I got it's first oil change at *200* miles. I got it's second oil change at *1000* miles. Every oil change after that was at *3000* miles. It now has 130k miles on it and it still sounds brand new. It burns zero oil between changes and there's zero leaks from any seals. I started doing my own changes when it was out of warranty. Since we have harsh winters here, I put in that mobile synthetic that's supposed to last 15k or 20k miles. That I will change after 5k miles or when it's first nice enough outside to change it comfortably. CHANGE YOUR OIL
I changed my oil every 20000 miles and my car has done 200000 miles.
yea been doing my own maintenance too not sure about the every 6 months thing let's say the car only hits 3k before 6 th month then should you change the oil? I suppose yes how about the oil fliter ?
why? ...
im sorry but an oil change at 200 miles is ridiculous
@@monkeyx17 I did my first oil change on my BMW motorcycle at 100 miles. The bike is 48 years old and still running fine.
I send my oil in to Blackstone labs. It took me 3 years to put 5,000 miles on my 700 hp Shelby gt500. They told me to go 7,000 miles next time even if it takes 5 years. They said the oil doesn't break down with age, go longer!
yp
Ron, even though you don’t drive it that many miles, you still may wanna take it out on the hwy every few weeks to burn off some of the condensation that may built up in the fuel system.
This is exactly the information I have been trying to ascertain and nobody has been able to give me a clear answer.Does oil break down with age?? Nope! I have the same thing with my truck that I don't put many miles on in a year.
Yes oil doesn't break down but additives in it do
@carlovanrijk4039 Yep, hit the pedal to the metal on your car on the freeway and get it to about 90mph, then slow it down and look out for the cops? Do it when traffic is slow and not congested.
Many people don't realise the number one reason why engine oil degrade and loosing it's viscosity is because of fuel dilution the engine oil because the fuel they are using doesn have enough or in America maybe 0% detergent in it. So what happen is your fuel injections system became dirty and it won't atomize the fuel enough causing for of thick liquid form of fuel and the engine will not able to burn the fuel causing it slips into the piston rings area into your engine oil. Another reason why the fuel turns bad loosing it's viscosity is moisture and lastly if you always run hard heavy load on you engine the polymer additive that responsible to keep your viscosity into certain degree will break the polymer molecules and you will loose your viscosity and causing futher wear. Remember the worse thing you do to your engine oil is to keep idle for a very long period of time and stuck in heavy traffic for long hours everyday counts as well beside your mileage. Is better to use cheap good engine oil and change it often rather buying expensive engine oil but dragging your oil interval at insanely long. So if you know how to change it yourself you save money from labour charges and change it when ever you feel the engine is no longer feels good or smooth when driving or if you really can't tell the difference change it every 5000km the max. Like me I stuck in heavy traffic almost everyday, I normally change the oil every 3500km or sometimes 5000km when I really have no time to it. I am using Shell Rimula R6 LM 10W40 oil because is a very good and cheap engine oil for my gasoline engine. This engine oil is meant for diesel engine but so far at 187,000km the engine is still smooth and my catalytic converter has 0% issues, I will say it is way better than Shell Hilux Ultra gasoline engine oil but way way cheaper. Is only $102 USD for 20 liters of engine oil here in Malaysia. Don't waste your money on expensive Pennzoil because it is Shell, Shell bought it in the year 2002.
Just starting to watch the replay of this premier now. I 100% change my own oil (and filter) for both of my cars. My BMW with the N54 twin turbo is drive very little, so gets an oil change annually regardless of miles. My Hyundai Elantra is my daily driver, with lots of short trips around town, so I change the oil at ~3K-5K miles religiously. I use top quality synthetic oil in both engines, the BMW getting a more premium brand.
I have a friend who changes his oil in an RS Audi at 6000 and then puts his used oil in the family car where it runs for another 6000 miles until it's due for a swap again. Thankfully they do take similar grades of oil.

... and you will achieve nothing except polluting more. Not very smart thing to do.
I change oil based on oil analysis. I start by having the oil analyzed at the manufacturers specified interval. I adjust the interval according to the analysis. In my 20-year experience of having oil analyzed on a series of vehicles from passenger cars, light trucks and farm equipment to help determine the OCI, in my particular operational situation, factory intervals are overly conservative in most cases. Especially as regards time. I extend them out generally, though one diesel tractor demanded a shorter hour interval due to soot... but that that tractor has 9,000 hours on the clock. I have seen no significant lubricant degradation out to three years. Indications are they could go more but I drew the line there. The cars and light trucks are now at 10K intervals and three years. The tractors are at 100 hours or three years. One tractor usually reaches 100 hours within a year and some, the other usually makes it to three years. I know of one tractor that sat 30 years in a dry climate and when the oil was analyzed, it was considered still suitable for use. Oil doesn't wear a wristwatch, nor can it read a calendar... but it does respond to environmental conditions and will degrade rather more quickly in damp storage or places where there are wide variances in temperature (condensation). Bottom line, it's all about the operation situation. And analysis can lead you to the right spot. FYI, I only use analysis to determine the interval and as long as my operational situation doesn't change, further tests are not done... except occasionally. I have owned one truck since 1987 (bought nearly new w7K miles) and a car since 2000. The tractors 20+ years. Have not have a single failure on anything due to my OCIs.
Yes, I want to see more time based test results from actual labs vs people just saying it goes bad. I don't think I've ever changed oil in six months or less. It's usually mileage or condition of the oil that determines when I change it, not time and I'm glad to see some analysis that shows that even after several years, oil can still be fine to use.
I only do 2000 miles per year. Changing every 6 months just doesnt seem practical. I do 1 year intervals with a long life synthetic.
That is not many miles at all so this seems very sensible to me. As said though it depends on how a person drives and the type of car it is. What sort of engine is this in?
@@torquecarsI’m just the opposite. My place of work is an hour away. 120 miles round trip. I may do 25K miles per year so I change my oil 4X per year at just over 6000 miles per oil change interval. I could probably go 8000 miles at 3X per year, but I like to keep the oil as clean as possible.
2016 Honda Civic with 2.0 liter inline 4 cyl, non turbo. 187K mikes so far on the clock.
Why use long life, when you only do 2k per year and change it every year?
I'd go up to every two, you're wasting resources & money.
I have a 2003 Toyota sienna that has 259.000 miles. I change the oil one time a month so the engine runs great.
My rule of thumb is: Conventional oil 6 months 5000 km / Full Synthetic 1 year 8000km. Never had a problem.
Put on a oil filter magnet. Will keep the fine metal particles away from the motor
@@benniestander2725 you mean "engine" . So many hybrids now , with "motors" .

@@torquecars normally aspirated engines. Petrol.
After replacing two turbochargers following the manufactures recommendations, I’ll be doing 5k max between changes and that’s with full synthetic.
Two turbos, ouch! What was that in? I found out that a local mechanic was using mineral oil instead of synthetic, the viscosity was correct and he didn't understand why people were getting so upset.
It’s your lousy driving, devon Gotta be honest wid ya
Is this one of the newer direct injected turbos? I've been seeing a lot about how they use a lot of oil, and I can't help but wonder if not keeping oil topped up is a factor for you.
idk about you or your driving style but seems like you should warm your engine more careful before flooring
and allow a cool down run before shutting off especially after a spirited session
I change my 1986 porsche 928S every 2 years with 8 liter of 20w50 non synthetic oil and drive less than 3000 miles a year and live in Southern California. My car has close to 200000 miles and does not burn oil and still running fine. I do my own oil change. Oil change should be done on engine operating hours. Short trip does require shorter intervals because engine does not reach normal operating temperature to burn off moisture.
Aww, a sensible sounding MoFo, with a killah set of wheels!
Think every 6 mo with low miles is too often. Didn’t see evidence that time per se is a major degradation factor
Yeah, you can easily go 12 months with any synthetic if your doing less than 6000 miles...
It's a good general rule. General advice should be conservative. Some people only run short trips on vehicles prone to dilution.
As a retired person, who only drives their older diesel vehicle about 20km once or twice a week, I have been relying on annual oil changes thinking that would be sufficient. After watching your video, I understand how oil degrades over time and I will be more diligent and have the oil changes done every six months from now on.
IF you get your oil up to full op temps on regular basis you should have no worries going annual on change intervals with such low miles, oil analysis would let confirm this.
Just use full synthetic and don't worry about it. Changing it once every 18 months is perfectly fine if the engine is in good working condition and it is driven warm most of the time.
I Have a 2010 Toyota Camry with a 2.5L 4 cylinder. I drive about 300 miles a week to work all highway miles 60 to 75 mph everyday. I use a full synthetic oil 0w-20. I have 250,000 miles plus on my engine. I change my oil every 5,000 miles. No issues and my engine doesn't burn no oil!
"Doesn't burn no oil".

@@CadillacDriver it does burn no oil or it does not burn any oil
0-20 is a bit thin for that engine with those miles.
@motleydude73 as long he's running 0w20 high mileage oil it shouldn't be a problem.
I really appreciate your videos! They aren't flashy or pushy or overly edited, but filled with great detailed information. Keep it up, new subscriber here!
It depends several factors. Long or short trips, dusty or not, aggressive driving or not, loaded or not, synthetic or mineral, etc.
Some great points there, and thanks for the support my friend.
Look forward to watching the video for sure but before I watch it - IMO - it's so inexpensive to buy 5L of oil that meets the spec (for 1.8T Beetle) that I do it every ~4 or 5k miles and replace the filter every second change. Will be interesting to see your results and other people's opinions.
It can be expensive but there are online suppliers out there, one I use is www.opieoils.co.uk and I tend to buy in bulk so it lasts me around 4 changes and in the long run I save some money. Buying oil is always cheaper than repairing an engine though, unless you change oil every month! lol
Absolutely agree many people don’t understand that it’s not just the mileage that matters in oil but like you mentioned other stuff like fuel dilution especially in GDI engines the dirt in the oil the oxidation
Have hung out on BITOG for years (Bob Is The Oil Guy). Most of the Blackstone test results you see there for good full synthetics don't even start seeing degradation of the additive packages until around the 8000-mile mark (US). I change mine at 7500 because that often divides into other service intervals nice and evenly, essentially maintaining 'like-new' performance of the oil.
Interesting, thanks for sharing, more food for thought here.
@@torquecarsthis is primo information concerning the life of engine oil and the recommended oil change intervals. The points you cover make absolute sense as to how oil degrades over time due to heat, contamination, blow-by, and etc. As I DIY my own oil changes, I am more focused on the intervals. I drive mostly hwy miles to work and back so my interval could be 6700 miles in a 3 month period. Blackstone Lab analysis states that the oil could conceivably reach 10K miles before needing to change, but I’ll leave it at 6700 miles for (hopefully) long-term reliability. (2016 Honda Civic). Although because winter weather is cold, I may have to stretch that interval to 8K miles. Not optimum, but doable.
Yes, but longer oil changes suspend more contaminants in the engine, accelerating wear.
additive degredation is one part of it, but what about liquid characteristics? fluid viscosity, friction & wear testing (how much lubrication does the oil provide between 2 rubbing metal parts & how much material is lost during a friction test)
But really, who cares if u are wasting by changing too often. Oil is the heartbeat of the engine. I change mine 6mos/5,000 miles. On my 2019 Prius. Yes, I KNOW it doesnt run as often but hot/cold/gasoline/condensation/direct injection? Pay now, or pay later. Your analysis if 6mos/8,000 miles is decent, maybe 6-7,000 the most. Great video! 👍🇺🇸
PS. I do my own oil changes and I drain it in LENGTH, & even TILT raising it to get it all out. It's so clean, u have trouble seeing it on the dipstick. My old 97 Camry had 265,000 miles & oil remained clean until 1,000 miles. I changed that @ 3,000 miles & ran like a top!
I only drive 2,000 miles a year so if changing the oil every 6 months I should be changing it every 1,000 miles.
Your videos are the best! I’ve binge watched loads now, can’t get enough of them so well presented, produced and easy to watch and understand! Thank you keep up the good work!
That is so kind of you to say, thank you my friend, it means the world to me that someone out there is finding this useful.
Every 6 months which is approx 6000 miles for me. A good quality synthetic of correct spec and a Mann filter each time.
VW approach: change the entire engine before reaching 50.000 miles 😉
On my Ford Taurus with a 3.0 V6 engine, I only used conventional oil in it. I was leery about using synthetic in it..I changed the conventional oil on it every 5,000 miles, not 3,000 miles as recommended. The conventional oil was dirty at 5,000 miles. That car lasted up to 160,000 miles until the transmission died on me. It wasn't wise to get a used transmission with only a 90 day warranty, so I got rid of it. The car I drive now recommends synthetic only. I checked my oil at 4500 miles, and was amazed how clean it was at the same mileage compared to conventional oil. The difference like night and day? I will change my synthetic oil at 7,000 miles regardless of how clean it looks. Engines are expensive, oil and filters are not.
.
Yeah, but they pollute a lot, expecially if you do your own changes and don't recycle it.
Just use full synthetic people, we are not 1968th anymore.
Since the last change installed timer which counts how much time the engine works, will change oil once it reach 250hrs of work (warmup, idling, congestions, city/hway) all will count as a work time
will see, currently expecting some 7+- k km once it reach 250hrs. in terms of calendar it'll be more than a year
Our two cars : 2008 Mini Cooper D . 108,000 miles previously fsh changed every year and twice in 1 or 2 years.Fully synthetic.
2017 Citroen Cactus 1.2 puretech 82 (non turbo!)
Changed 3 times since May 2022 . This puretech has a WET timing belt , hence the need for clean oil . Fully synthetic only allowed on this one , currently on 56,000 miles.
Interesting and informative video. I know little about this, but just from a logical perspective I'm always a little skeptical of the information. Because IMO attitudes about oil changing are often akin to cleanliness. Purists and the absolutists abound. For example, you'll find people that flush automatic transmissions rather than do a pan/filter job, even though manufacturers generally don't recommend it and it is known to cause problems, because some people just can't handle the fact that not all the oil will be drained from the transmission.
Likewise, in these recommendations you seldom see anyone refer to how much oil is used between changes. Many cars use a quart every 2k miles or so, and always have and always will. My car has always used a quart every 1.5 to 2k miles (which is normal for these notoriously long lasting engines as far as I know), and so after 7k miles or more it still looks almost new and smells great. Because it is mostly newer oil. I certainly don't change it every year if I'm under 8k miles. Under the mild conditions under which I drive, I commonly go 2 or 3 years. Here is where people will stridently claim oil turnover makes no difference, because without changing it you're not removing 100% of the old oil. But of course, you can never remove 100% of the oil and probably 1/2 quart gets left behind during oil changes depending on the oil pan design.
So I can't help but wonder if the real issue at this point isn't wear of beanings, rings, and camshafts that should determine oil change intervals as much as whether an engine has a turbo, direct injection, VVT, and possibly long & complex timing chain paths that many dual overhead camshaft engines now have. My car isn't new and has none of those features. VVT in particular I am told, in which the oil serves to move hydraulic actuators, is very sensitive to additive levels.
This is one of the most polarizing subjects I have covered, with passionate debates on both sides.
These new technologies certainly hammer the oil and is probably the reason why many have really short change intervals.
My oil has been sitting in my VW for for 10 years. I only drive it 100 miles a year. It’s still looks brand new and runs smooth as silk.
🤣
I Was talking about my 84 Suburu with 250.000 miles with no oil drains on RUclips. A Caterpillar lab manager sent me a sample kit. He said the oil looks for that many miles. He found some caramelization. He recommended I change the Frantz oil cleaner every 6.000 miles and add a quart of Mobil 1 instead of every 12.000 miles. The Pontiac Torrent uses a Australian Jackmaster Classic oil cleaner and Walmart synthetic oil called Super Tech. I do 6.000 miles now. I started in 1963 with a Frantz oil cleaner and Delo 30 W. The Motor Guard oil cleaner on the old Ford 390 is over 50 years old. I still use a few Gulf Coast filters. I like the top loaders. I have a flat head Ford V8 canister filter on the old diesel tractor. It has half a roll of Viva towels in it. Cant get good cartridges for the old canisters these days. I am a filter guy. I dont run on dirty motor oil. I drive mostly highway.
I just bought a Trax 2024 - 3 cylinder 1.2L turbo. I'm getting the oil changed at around 800 miles, then at 3000, then follow a 6 month/4-5k mile schedule.
Every 4000 miles or 2 time a year.
I live in Québec Canada and winter is tough on cars so I like fresh oil before winter. Thanks
If your fuel economy is 60% to that of mfg then do it at 60% mileage then what is mentioned in the service book. Stick to fuel economy percentage of yours compared to manufacturer declared. You can still take 20% leverage on that. Manufacturers will assume 80% highway run 20% city, same as to show average fuel economy.
Hi, agree to all said.Myself i change oil at 25000km without a worry. I am using "polytron mtc". have done oil analisis every 2nd oil change. 43+000km on my dash, jetta 2003 alh,manual.
Thanks for sharing, do you find the analysis is consistent each time or do you notice an acceleration of degradation?
@torquecars opposite, I find it more responsive. I am not the only one noticing this. We're about 300+ cars owners. I have few oil lab results. Let me know if you want it
Yes please more data to work from is ALWAYS appreciated. Can you email them over to me when you get a chance?
@torquecars sure. Give me your email. I know I might find it but I am 60+ not so much in to this
I hope I don't buy you car by accident
Interesting, but probably most viewers would like to know specifics. Whenever I visit an oil change facility, they all tend to push you into shorter intervals like 4 to 5 thousand kilometres. I use synthetic oil in my Toyota Corolla 1.3 and change the oil and filter after 10,000 km.
I changed the oil every 6 months in our Audi A3 in the last 10 years and I do it with our vw golf estate too. Total cost £40 (oil+filter) half the price garages do it in the UK
I wait for the Oil offers. Mine is around £25 total to change.
I don't use really expensive oil mostly Mannol Fully synthetic 5W-30 which is cheap. And a decent Filter.
I believe you can use a lower cost oil as long as it's changed more frequent. 4000 miles or every 6 months.
People can keep debating engine oil change interval for eternity; nothing can destroy the engine faster with insufficient oil level in the sump. So please do check the dipstick at every fuel stop.
I do not do high mileages, so I do my changes at 10,000 kms or two years, whichever comes first. I have tested the oil since buying the car and it always comes back with comments saying that it is fine & not showing signs of wear or changes compared to previous tests. I do my own oil changes.
Can I ask do you do short running under 20 minutes much or is it mostly longer trips?
An oil analysis is the best way to clarify how often you should change your oil.
Normally the manufacturers recommendations are pretty accurate (10,000 km is pretty accurate for our Toyota Yaris)... although I wonder about some of the really long oil changes.
However, changing oil every 6 or 12 months is a waste of time. The oil doesn't go off just sitting there. Any oil analysis will tell you that.
Change oil based on km travelled.
🙂
A synthetic oil lasts longer than a mineral oil:
A semi synthetic is almost as good as a full synthetic.
If you want to extend the oil lifespan a bit longer try a high efficiency oil filter (removes more particles), foam air filter (less dirt) or bond a lubricant to the metal (XcelPlus).
All 3 of those will also reduce wear in an engine sometimes dramatically i.e. Up to ~90 %.
🙂
BTW: I've noticed that cars that have 20,000 km oil changes have twice as much oil as cars that do 10,000 km oil changes.
Conversely motorbikes that change oil every 5,000 km have about half as much oil as cars doing 10,000 km changes.
It makes sense that the oil would last twice as long if there's twice as much of it.
So perhaps the longer oil changes aren't as unrealistic as people think?
For some reason nobody ever mentions the volume of oil being used when having these discussions.
N.B. An oil analysis would soon clarify this issue.
:-)
Unless you run a huge fleet of vehicles; the cost of oil and an engine filter is minimal, especially if you service it yourself. Car manufacturers are in the literal business of making sales. They do this by showing decreased servicing cost from longer service intervals. They frankly care only that the car makes it past the warranty with some buffer. If it is worn out, they know your going to buy a new one. My advice is service the car with competent people that aren't likely to induce maintenance faults. For me that is myself with cars.
Oil is cheap engines are not between 2000 to 3000 miles I do it myself and use Mobil 1 or Pensoil ULTRA
You are right oil gets dirty.. The Head engineer for Nissan on Automotive Press says change it at 2000
I change mine every 5k miles or 6 months absolute max. Usually 3k-4k miles. Synthetic, new filter every time.
Is that excessive? Not for me it's not. For others, it might be for whatever reason. If you drive hundreds of miles a day, 5k-7k mile oil changes would make more sense.
This is not a settled argument and never will be because the answer is catered to individuals and their circumstances. I will say this though- too infrequent oil changes can damage your engine, while frequent oil changes cannot. That is an undisputed fact.
I used to change oil in my 77 cutlass supreme 350 4 barrel every time it got dark. Now 5 to 8 thousand with 3.5 ecoboost ecoboost, Godzilla and V10. Penzoil Ultra Platinum 5w30.
5000 mi / once a year with oil analysis, so far so good
When discussing the topic of oil changes, it is usually forgotten that the engine lasts longer than the car itself. It also seems to be forgotten that engines very rarely break down due to incorrect oil change intervals. Just do what the manufacturer recommends and you'll be on the safe side. If you have too much money, change the oil as often as you want, it will only calm your nerves.
engine oil can still be fine even after 2-3 years, if it is longer in it than that then you should change it, according to an oil analysis
i change my oil anywhere from 5,000-7,000 for synthetic but for older vehicles every 3000
I do oil changes every 6 months / 7,500km, whichever is the earliest on my 07 Merc v6 Diesel. I change the oil filter every second service.
A good rule for changing oil in diesels is to put oil from the dipstick onto your finger, and then wipe it off your finger. If it cleans up perfectly, then the oil is still clean. if it leaves black stain in your fingerprints, then it needs to be changed. when oil stains stick to your fingerprint, it means the oil is saturated with soot and is not cleaning as effectively anymore.
Manufacturers recommend 15,000km or even 20,000km these days, which is ridiculous.
The reason why manufacturers recommend longer intervals is so they can advertise a lower running cost of the car as a whole.
Also, if someone changes oil at 15,000km or 7,500km, they will not notice any difference in the car's performance in the first 10 years of the car's life.
These differences start appearing after 10 years or 200,000km, which is well beyond the warranty period of the vehicle.
This means there is no incentive for the vehicle manufacturer to make oil change intervals more frequent.
I tend to do every approx 8k miles on both my car and work van, my van is a 63 reg Vivaro and the oil still looks clean after about 6k
I change my oil when it gets dirty. For my daily commuter vehicle that is about 1500-2000 miles. In my opinion mileage is a terrible indicator of when to do maintenance. Engine hours is the best way to schedule maintenance. For an example some people live in the middle of nowhere. They might get on the road and drive at 70+ mph all the way to work and back. This person will have 7,000 or more miles in 100 engine hours. I’m on the other extreme I drive in an area that had horrific traffic. I don’t get over 20 mph on my commute (the average speed is probably about 10 mph) and sit stopped on the highway for several hours each day. In 100 engine hours I’m lucky to get 1000 miles! Assuming your going to change your oil at 250 hours ( I prefer 100 hour changes but I’m very anal about my equipment) this can work out to 15,000 miles for someone who lives in the middle of nowhere or 2,500 miles for someone who lives in a congested area. Car manufacturers are going off a 250 hour service and an average speed of 40 mph when they say change the oil at 10,000 miles. I’m willing to bet most of us won’t even come close to an average speed of 40 mph if we are commuting to work! Assuming an average speed of 30 and a much kinder 100 hour service you get 3,000 miles. My advice is change your oil at 3,000 miles or 100 hours if you have an hour meter. I am religious about 100 hour oil changes on the gensets at work and they have been lasting over 40,000 hours! That’s roughly double what they lasted with 250 hour service!
I must add car manufacturers know that mileage is a terrible way to judge oil life. This is why they have a time interval. Your oil doesn’t go bad from sitting (at least not for a few months or a year) this time interval is an attempt to keep you from putting a shitload of hours on your oil if you drive in heavy traffic. Unfortunately this is also a guess that assumes you only drive a certain number of miles/hours a year. Some vehicles that have a oil life monitor actually count engine hours. This is a much better system but unfortunately it’s usually based on a 250 hour service interval. My advice is to change your oil at 50 or 60 percent oil life if you have said system. Beware some of these systems just count mileage and are truly useless so keep that in mind. The easiest thing and what I do is change when the color of the oil on the stick becomes a darker color. It might not look dirty but when you drain it it will be black. Unfortunately I can’t show you this shade but I know what oil with 100-150 hours on it looks like from decades of experience. Investing in an hour meter is your best bet. These hour meters are dirt cheap and very easy to install. A simple oil pressure switch can be used to power them when the engine is running.
I used amsoil ss in my honda 1.5L N/A engine for as long as 7k km (~4.4k miles) in 9 months usage period. after doing oil analysis, I was shocked by the oxidation level (at 59). while most of the wear metal numbers were low, the lead (Pb) was of 10 ppm. Although 30 ppm is usually the upper limit of Pb but I wasn't satisfied with the result. I'm switching to 6 months duration regardless the mileage to improve oxidation, but it means I have to use cheaper oil because amsoil cost just doesn't justify. the car is used in tropical country where outside temp is quite hot.
Your experience really does show the importance of not assuming and getting a proper oil analysis carried out. Thanks for sharing your experience.
I dont drain oil. But I drive mostly highway I dont have a turbo. I use depth bypass filters.I change the filters and add a quart of new synthetic oil every 6.000 miles. In the 60s I used depth bypass filters and Delo 30 W and changed the depth bypass filter every 2.000 miles. One time I had to drain the oil and change a head gasket but other than that I havent had engine problems. I dont go over 250.000 miles on a car. There several filters that clean oil. The Pontiac has a Australian Jackmaster Classic. My oldest filter is a over 50 year old Motor Guard on the old Ford truck..
I do it every 15.000km. Never did it by time but it never took more than a year to do that amount of kilometers for me.
I change the oil in my vehicles when ever the oil life gauge drops to 50% oil life remaining. Approximately every 5000 miles.
I have 2.0 Tdi PD 103kW BKD changing oil every 6 month or 6200 miles. Also change the oil and air filter. Once per year change the fuel and the cabin filter. I do it myself, I dont have any problem with my engine. I never sent the oil to the laboratory.
Do myself since dealerships overfill and sometimes don't change filter. Always change synthetic blend/ full synthetic and filter every 5000 miles or once per year whichever comes first. Oil is cheap, pistons & rings are expensive. 🙂
Most newer cars are using turbo engines, change your oil every 4-5k miles with full synthetic if you plan on keeping your car long term.
I change mine around 4k miles myself. There are lots of rippoff behaviors in the US mechanics😅
Depends on driving conditions.i just look at it and change when it gets to dirty.my 95 vette i drive mostly highway but its hard driving.usually around 3000 miles mobil 1 pure synthetic.my 99 infiniti might get away with close to 5000 but again i CHECK IT REGULARLY! Also i have a 06 mdx which i take fishing 40 miles total trip but i idle the car around 3 hours straight because i hate heat cold and bugs.so thè mileage would be low but oil is taking a beating so like i said driving conditions and check it regularly!
When changing the oil is cheaper than the oil analysis, just change it!
Driving with low revs while the engine reaches normal working temperature is good for the engine.
I got a 2024 Chevy Trailblazer RS I change my first oil at 800 me the second one is being done at 2000 and then every 3,000 after for the life of the car
Hi! My story. I use Mobil 1 5W-30 EO with my VW Golf Mk2 (1983 year) with secondary engine of 1992 (year about). I drive with this oil very long time and engine stops working because of lost viscosity. If I calculate properly - I add 2Liters of oil every year, because of piston rings wear. That means - I partially "change" oil with new and I change oil filter every 5 years... Total time was about 15 years in this "conditions". My engine (I was lucky) stops inside garage... and I was able to do job inside. I drain oil - no viscosity - like liquid sour cream, remove oil pan, check oil pump, inspect piston "legs". Everything was in very good condition. Than I remove crankshaft and find 1 stuck`ed valve, but it was not bent!!! Just stuck`ed. I reassemble everything back, add 5W-40 Mobil engine oil, than I start engine which was very noisy, remove deposits on the valves with Carburetor Cleaner + Water and my VW Golf is back on the road! P.S. Yes - please change your cars engine oil! Some recommend after 8000km, some after 5000km... maybe 12000km is last chance? Be Happy!
Thanks for sharing your experience it's always good to hear other peoples opinions on this. Good advice - be happy.
i do it every 8,500 i dont do city driving so that helps alot no start stop constantly
For my daily driver, 4runner, 5k or 6 months. Never hit 6 months though. For my 1991 Nissan 300zx twin turbo, 3k or 6 months. I only put 2-3k a year though and mostly drive in spring summer months. I do full oil and filter change in spring, if I have not hit 3k miles will just do oil drain and fill in fall
Changed my oil every 10k miles with supertech oil from walmart. My car has no problem, 300k miles. I think, ir is more on how you drive your car
With cam phasing and lengthy bicycle size timing chains, you had better change it often, for it is the Achilles Heal of most engines.
I change the oil according to the owners manual which for me is 5,000 miles or 6 months. I do about 5,000 miles a month and change my oil monthly.
Years ago BMW ran a car continuously for 1,000,000 miles stopping only for refuelling and scheduled oil changes using Mobil 1 0W 30. After the car reached 1,000,000 miles the engine was completely stripped and all parts were found to be within manufacturing tolerances.
Old engines were better built than modern ones. Manufacturers later realised that long lasting engines were not a good business model. Modern engines now contain lots of plastic components which wears out faster and need frequent replacement, again, a good business model. Therefore, regular engine oil changes make a lot of sense, especially if you plan to keep the vehicle for longer.
Looking forward to this one.
It was an interesting one for me to research and has taken almost a year in the planning as you'll see when you watch it.
I have a ram 2020 2500 power wagon I change my oil every 15,000 miles and I use the cheapest oil possible and the cheapest oil filter my old filter I’ll let it go to 30,000 miles I have 43,459 miles everything‘s going well I think I can get 350 to 400,000 miles out of it if I continue to stay on top of it and do my oil changes regularly
1 I change the oil after my first 1,000 miles.
2. change after 4,0000 miles or 6 moths.
3Then after 5,000 miles or six months.
DIY oil change is quite easy and inexpensive. Here in the US full syn is still about $20 including filter at Walmart Supertech. I do often at 5K-7K miles depending on the type of miles I drive. I may go 8K if it is nearly all uncongested freeway miles.
3K even with full syn if mostly city or congested freeway miles, creeping 15 miles in 45 minutes type driving.
I change my oil at the start of winter and the end of spring because I only do short journeys.
It depends much on the oil, driving, and sump capacity - if I was using a cheap mineral oil and short distances on an ordinary car maybe 3,000 miles - I use Profleet synthetic, fairly long haul, and an oversized sump and filter so 6,000 miles +
I believe 6 months, or 5000 miles is a good idea even if oil still lubricates well i thing you will get sludge buildup if you go too long, have stretched it out to 10 months when only driven 2000 miles but i found one car had foamy water oil buildup under cap from being only driven 5 minutes to work by kids.
My question.is...if you use 100%synthetic oíl and you onky soend 3k miles per year on short 1 mile trips..do really need to change it yearly?
My Jeep has not been out of the garage in two weeks. At this rate my next oil change will probably be in about 5 years...maybe.
Rickss69, you may wanna take it out on the hwy every few weeks to keep condensation from building in the fuel system. 👍🏼
I gave up allowing the oil to get dirty and oil changes in 1963. I use filters that clean oil and I try not to start the engine unless I plan on heating up the oil. Shutting off a cold engine is bad for engines. You want the PCV to do its job.
You will NEVER hurt an engine with fresh oil and filter . My son and I spend recreational time together in the driveway every 5K kms . Cheap and fun .
You have him well trained, a future mechanic and car enthusiast I'm sure.
If I had a son I would spend a minute teaching him how to change the filter element in the Australian Jackmaster Classic bypass filter. A lot better than allowing the oil to get contaminated and draining it. We dont do dirty oil in my family.
50,000Km here on amsoil with regular oil analyst every 5000km if the oil is still good why change it
now I'm trying Hotshots black diamond outlaw oil 15w40 lets see how long this can go.
Change it every weekend or second weekend, whichever occurs first
i change for the season. it only takes 15 minutes i don't even have to jack the car up.
i Changed oil every 3 months/3000 miles. My car has almost hit 500,000 miles. Changes your oil 10k, 12k, or 15k than you might 250,000 out of your engine.
You certainly are taking no chances, conservative but effective. Assume you are same on air filtration and coolant? Bet the internals on that engine are clean clean clean.
It took me about 20 years to put 250.000 miles on a 84 Subaru with no oil drains using a Frantz oil cleaner and Mobil 1 15 50. I gave up the dirty oil and oil changes in 1963. My Pontiac has a Australian Jackmaster Classic. I like the top loaders.
I have a 2007 honda odyssey and always change my oil 5k less w synthetic. When i had to redo my bent valves, i was so surprise how clean my engine was.
Show if u take care of ur car, the engine can last a long time.
Oil is cheap, engine and labor expensive.
j.t., I work at a Honda manufacturing site (we build the CR-V’s and Civic’s). I’m with you on the more-frequent oil change intervals. As my family mostly drive Hondas and Toyotas, I’m a stickler when it comes to regular maintenance (I do the maintenance myself) - it keeps our vehicles from going into the shop.
How did valves get bent , was timing belt neglected ?
My SUV doesn't get driven a lot so it gets annual oil changes, which is what the manufacturer recommends if it doesn't do 10,000km a year. But my Triumph motorcycle is what I commute to work on and, while the manufacturer recommends a 10,000km oil change interval, I simply do not trust the 3.2 litres of Castrol Power1 Ultimate synthetic oil in the sump to last that long in our hot tropical climate without succumbing to evaporative losses. And my bike gets revved twice as much as my SUV. So I change the oil at half the manufacturer's recommended interval.
Awesome ❤another great video
Colour is a good indicator?
Yes . I change mine when it turns green.
OIL is relatively cheap……twice a year. UNLESS your oil change cost $245.00 (like my neighbor’s Porsche) then I would change it every 8 months… I am 73 yrs old, with spine problems (don’t need to be getting under a car) My local Toyota Dealer charges $79.00 for full synthetic oil & filter plus a full inspection. Pretty good deal for me.
I am in the UK and my partners 2016 Audi A1 1.6 TDCI manufacturer users manual states 10k miles or 1 year for oil 5w30 fully synthetic. I has 52k miles on it. Why should I change it less than this interval? It is expensive in the UK to get a fully synthetic oil/filter change. Cheapest last time was £120.
You don't say if syn is better and can last longer before changes. I think you can double your change intervals with syn.
Synthetic is loads better, mineral oils tend to break down when they take a beating inside an engine. I guess this is why most turbos require fully synthetic.
I have known some mineral oils to be labelled as synthetic in some regions which doesn't make a lot of sense to me.
I use high grade 0W-30 for Honda diesel, I drove in 2 months what the previous owner did his last year of ownership LOL.
I do many trips 400km+ daily. Filter and oil sets met back 55 Euro, every 10000km, DIY job. 10 minutes.
Never skip on oil change.Interval depends on type of drives and content of the oil pan. Honda has 5.9L on 2.2 4 cyl 🛢
I have 232k uk miles on one of my engines and i change the oil every 4 months between 7000-9000 miles... seems fine...do not have a clue in uk were you could send a sample of oil to a lab so a enlightment would be apreciated.😅
Last time I tried to post links here the post got deleted, when I did a search on Bing I found quite a few "uk oil analysis labs" millers, the oil lab, oilsamplingcouk and my personal fave is Ravenol which is pretty low priced but didn't include oil fuel dilution tests IIRC.
Look it is the manufacturers that want your service when things go south on your engine. So change it as you wish. I do it every 3 thousand miles for my satisfaction and peace of mind.
Between 2000 and 5000 miles here on both cars depending on usage, one turbocharged Subaru, the other a turboDiesel Prado.
I try to find Diesel specific oil for the Diesel engine for the hopefully higher detergent content.
Have never gone long intervals in any of my cars because i do all my own work and bought in bulk packs of 20 litres oil is cheap, been decades since i had an engine or transmssion issue, trans get serviced too, any sealed for life cobblers there is unceremoniously ignored.
What the hell is sealed for life or long life when a car is concerned, anyway, most makers couldn't give a toss once the warranty has expired so for too many makers long life or sealed for life means 3 years then if it gos bang tough, you don't find Toyota who offer 10 years warranty if you get the car serviced by them recommending 24k miles oil changes, wonder why?
Just as important for engine (and turbo) long life is warming the engine before driving it hard and allowing turbocharged engines to warm down for a minute or more idling gently after driving to allow the turbo to cool down, at least one minute more if you've been driving hard.
They say there is no need for this any more because apparently water cooling carries on after shutdown these days, well i've covered getting on for 4 million miles now in turbocharged vehicles, have always allowed them to warm and cool, and am yet to have a turbo failure, my method aint broke and see no reason to fix it.
Oil changes every 10.000km/1 year. manufacturer recommendation 20.000km/1 years. Oil is cheap cam-chain replacements are not.
For GDI and turbo charged engines, every 3000 miles. For naturally aspirated and port injection engines, every 5000 miles. Just follow this and your engine will cross 600,000 operating hours without any problems.
With every oil change; oil filter replacement is mandatory.
Does oil change interval differ depending upon where you live? The environment I mean
I don't think so, but I've only really got UK experiences. As far as I know the Service schedules are the same in each region. Sometimes oil specs and fluid specs are different.
Extreme hot like Australia or cold Canada or even very hilly places like Nepal would make a big difference compared to a very flat place like Holland . And if you live near me the potholes in the road will take a few years off your car as well 😉
@@paulgilraine3127I agree. Even drastic changes. Best to change 6mos/5,000 with OEM filters & GOOD brand of oil. Not 'Joe Blow" brands
I use to do it in the 1960s every 3000 miles. By the 1980s, the additives in the oil made it superior. So, 8000 miles was recommended. Now, go onto RUclips and watch the tests. 10,000 miles is now the target here. However, dealers want your money, so they still say to change it every 3000 miles.
I've not heard of any oil manufacturer now recommending 3000 miles, though car manufacturers try to sell the idea of long service intervals for fleet buyers and reduced running costs to private buyers - they are never a good idea for any engine optimum longevity. It isn't just that oil technology has improved with both additives and synthetics but machining tolerances too and material durability have vastly improved. Engine rebuilds outside of exotic performance cars are rarely heard of now, whereas it was very common when I first started driving. Most smaller engines here in the UK, in the 50's and 60s would be lucky to last 100K, even with 3K oil servicing, even the legendary XK engine. Nowadays even petrol engines can last far longer and diesels can can cover huge mileages, but rarely ever with long service intervals. The price of an oil and filter change is less than a full tank of fuel in most cars these days, at least here and so 6 months/6K is not a huge price to pay, for often incredible engine life.
In the 60s I didnt drain oil in the Rambler American. Every 2000 miles I changed the Frantz oil cleaner and added a quart of Standard RPM Delo 30W. Delo was beautiful when clean. I still dont change the oil in the Pontiac but I change the Australian Jackmaster Classic every 6000 miles and add a quart of Walmart synthetic 10 30 oil. The oil is clear. Im told I wont get to oil change heaven.
Very good informative video.
