What if you forget to change your oil on time? Can you damage your car's engine by not changing the oil late? Do you really need to change your oil every 3,000 miles? Obviously, you should change your oil regularly, but exactly how much damage you will cause by changing the oil late? This video looks to answer this question. We'll discuss what happens to oil viscosity as it ages, and what happens to oil additives in over time.

I went 50 miles over, so I just drove backwards before I changed it.
Thank you for the tip
Outstanding move
This is the kind of thinking that has made this nation so great!
Does this actually work? asking for a friend
The old Ferris Bueller method.
I’m an engineer by profession and love those engineering videos. Reminds me of college days, 30 years ago❤️
Can you do work for me on 20 Micron filter media?
My decades of experience are all the way back to a heavy steel cannister with cartridge's in it;
My experience shows "just replace it often enough"
Bluecamaroz28: Agree. Retired engineer here and it was more like 50 years ago!

@@dd_ranchtexas4501 I filter biden out most days.
Daymn u old
Years ago I took a class in college on automotive technology. The professor had a PhD in automotive engineering. I learned a lot in that class. The one thing that really stood out is the professor repeatedly making the point that oil is not just a lubricant. It is a coolant. The oil helps limit heat buildup in critical parts of the engine. Not just by lubrication, but by moving heat away from critical parts of the engine.
This! This is why my engine got fried and stuck, with no oil! Mechanic said, "I was responsible" to check the oil level every two weeks. It was gaslighting. I had the scheduled regular maintenance with the mech, just 3 weeks prior to getting fried. $3000 price tag for engine swap. Plus tow, plus stranded in hwy etc. The car was regularly and meticulously maintained. But oil got lower in... 3 weeks??? Bummer.
@@JR-zw2vb Yes person should check their oil but eating so much oil it starved the engine in 3 weeks. Something seriously was wrong. I do check my car almost daily i probably lose more oil from wiping the dipstick clean but thats just me being OCD.
@@DeusKDuoThat's not OCD. In 2020, I used to be a delivery driver averaging 150+mi./day, and I used my own car('02 camry), and I checked the oil level every morning before starting the car. B/c the camry had to endure so much city driving, I ran a full synthetic, which I changed every 3k mi. And running a flush through the the engine every 5 oil changes. It's been my daily for the last 3yrs, and I left that job 2yrs ago, but It still runs very well, and I still run the High Mileage platinum full synthetic from pennzoil but change the oil every 4k mi. now. And I still check the oil at least once/wk. I love that old camry, and I know it was worth doing all the oil changes myself. Besides, the oil change service was super easy.
@@lobsterbisque7567that’s a testament to your Camry’s robustness!! About 8 months ago, I bought a 2015 Venza, which is based off the Camry platform, and will serve as my retirement car in a few years. It currently has 105K miles, and runs like a top! I’ve done a couple of oil changes on it, and it doesn’t burn any oil. I plan on babying it and who knows? It may last another 200K-300K miles, that’s how tough the Toyotas are. Kudos to you and your Camry!! 😃👍🏼

@Cliff Warren, Lol
I got a 2002 hyundai minivan. Goes great. Because it was A COMPANY CAR and NEVER MISSED an oil change. That's the secret. My family has had a number of company cars (including my latest ford) and they've all been good JUST BECAUSE they never missed any services.

Which is why operator manuals just tell you when by a generally straightforward set of conditions. The average Joe and Josephine just want an easy answer so they can go about their lives. People watching "Engineering Explained" aren't those people.
Hahaha best comment. I actually work as a manager at one. Watching this video to actually expand my knowledge in this.
I was that guy. just didn't have a white board.
Here's a true story no one is going to read:
My ex girlfriend ran her 97 honda civic mb2 almost everyday for over 4 months without oil in the gearbox and waay below the minimum in the engine. One day the second and third gear started making the same noise as the reverse gear does, and first gear wouldn't always click in place. She complained about it and I'm a handy guy so I decided to do the maintenance of her car like a real man. NOTHING had prepared me for the moment I took the drain plugs out just to see *literally* a couple drops of oil from the gearbox, and the equivalent of two cups of water from the engine.
Since that day i've got MAD respect for old Honda drivetrains.
The car still runs great at the date of this comment with the best quality oils I could find for it ..
To this day I have no clue where that oil went .....
maybe they forgot to put the new oil in the last time when they were changing it before to do the maintenance that time so it was never there to begin with hehe
@@raven4k998 yes. Either that or it was stolen. And I know which theory sounds best 🤣👍
@@MasParaQue motor oil thieves you got gotta watch out for them they will strip your car bare in a couple of days if you not careful hehehe that's why you should always have a shotgun ready on standby incase they come for your car
I had a 97 Civic, for over 2 years I would hit rev limiter numerous times daily, even on a cold engine. Drove it 750 miles a week and abused it every mile I could. Also ran it out of manual trans oil, but it killed the input shaft bearing, so I sold it. Engine still ran perfectly, great cars.
Here's one for you I'll never forget- i was a lube tec for 2 years. One late 90s civic came in, running fine. Guy is crowing about how the car is his baby. Pull the drain plug and NOT ONE DROP OF OIL COMES OUT OF THE CRANCASE! Changed the filter, fill up new oil, and he's back on his way.
My dad's secretary came in one day and said her car was making a rattling sound under the hood. My dad went out to take a look. He pulled the dipstick, clean. He asked when she had her oil changed last. "Do what now?!" 49k miles never been touched. LOL.
@Grizzly “smash her”?? Don’t know what the car was. This was over 30 years ago.
@Grizzly oil wasn't as good then but then engines weren't so sensitive back then either.
It depends on how much your cars engine is worth to you on how often you change oil. Problem is that the result of neglect will only show up after years of neglect.
You can't hurt your engine by changing the oil too often.
Well done as always, Jason.
Thats how i deal with for me my car engine is like my heart and im always in serach to increse its life and have fun with it
whereas i also have a scooter which i dont care about much skipped many service but that thing doesnt break
You have no idea how mad I was at my dad once for driving my Corolla nearly 20k miles without an oil change, and doing that for a whole year.

Thank you for the information and excellent explanation. Note: as a fleet & logistics manager for Pepsi cola, we send the used oil's to a lab for testing to determine the proper oil change intervals for various truck types that we own. As a rule of thumb you can go twice the recommended mileage. Since we run hundreds of trucks and vehicles, the sample is adequate to arrive to a conclusion that is valid within our application, vehicle types, and the type of oils we use (none synthetic).
All persons talks of mileage but what about time?
@@LibertyWlk yes, we are low mileage family , our car does 3 to 5 thousand miles per year at most, so we often dont change it every year and never had any problems , we buy 3 year old cars and run them for however long we feel like which is usually 10 years or so.
@@FlyingFun. It also depends on what type of "low mileage" one has.
If all are short trips, these are actually bad for the oil. Cold engine = fuel vapor condense onto cylinder wall & doesn't burn, wipes right into crankcase, dilutes oil, etc...
If each trip is reasonably long, just few trips each week, that's probably the best combination for the vehicle...
@@reallifeengineer7214 I knew short trips were bad but thanks for exact reason why.
Commute is about 20 miles and weekly shop just a few miles away.
I'll defo keep an eye on the oil.
In my previous work I was doing loads of 5 minute journeys with 30 minute between them and oil got pretty black quite quickly.
@@FlyingFun. best way to go about it is to check your oil every weekend. I've found all other advice too general and now I just check oil every Sunday and going good🤙🏻
How can you tell when your subaru is low on oil?
When in stops leaking all over your driveway.
Lol...😂
I thought the answer to “how do you know your suburu is low on oil” is
“Yes. “
Between the leaking and the burning. A friends brand new forrester has burned a qt/1k since it was new off the lot. That’s “normal” according to suburu. 🤷♂️
My 93 Legacy hasn't started leaking oil yet at 237,000 miles. The 84 started leaking oil from both head gaskets at a little over 250,000 miles. Paid 200 dollars for an 80 model Subaru unseen. Went to pick it up. The floor was full of empty oil cans. Oil was all over the engine and the fill cap was missing. I got lucky replaced the cap and changed the PCV valve and hose. It wasn't very old then. Took a kid thru college.
@@ralphwood5114 Hello Ralph. I believe the engineers simply forgot to design in the oil leaks on the earlier models. Something about 80s and 90s Japanese build quality. Speaking of which, what ever happened to that?
I mostly buy old cars. The 84 I bought new. Bought a 2008 Smart car. What a piece of crap. I liked driving it. It was sweating oil when I bought it. It started leaking bad about the time I started having electrical problems and parked it. It was burning out head light bulbs. Voltage seemed OK. Not a do it yourself car. Its a take it to to your Mercedes dealer car. Don't want any more cars that I can't take to any locksmith and have a key made. Its a 5 speed manual. The computer works the clutch and shifting. 150 k miles on it. Not worth much.
I had a Mondeo and went 1000 miles over the oil change and my girlfriend left me and then half my house fell down a sink hole
It was because you drive a Mondeo
If you had have driven a kia you could have gone 7000 miles over the oil change, killed the engine, gone around telling everyone "it's because kias are crap", and they all would have believed you. But just don't tell anyone that the Kia Sedona used as wheelchair taxis here in Australia got about 660 thousand kilometers because they were maintained.....
Maybe she just fell into that sink hole. Feeling better now?
There's yur problem!

As a note, many additives are also dual purpose. ZDDP (commonly referred to as just "zinc") is an excellent anti-oxidant, especially ZDDP that employs primary alkyl groups. MoDTC, a common friction reducer, also aids in oxidation inhibition as well as helps with wear protection in high concentrations. Unfortunately, both of these are severely limited in modern API oils because of "emissions." CaCO3 and MgCO3, the core of calcium and magnesium based detergents, can also have anti-wear capabilities.
*What an informative video! It's so important to understand the impact of something as seemingly simple as an oil change on our cars. Your breakdown of how oil viscosity changes over time and the effects on engine health really sheds light on why regular maintenance is crucial. Keep up the great work, looking forward to more insightful videos!*
Excellent Stuff, there is a reason this channel has been around so long.
Also worth mentioning some of the newer systems on engines like variable valve timing have smaller passages and are more sensitive to oil condition.
They are a lot more particular about the oil weight and condition. Wrong oil or long change intervals will not be good for it.
You are correct. The hydraulic lifters that adjust the valves have tiny holes that need to be filled with oil to function properly. Sludge plugs those holes preventing oil from getting inside. Then you have tapping noise.
And yet manufactures are extending or claiming changes of up too 15k miles. Sounds like a cash cow for the manufactures for repairs.
@@djmjay2 that’s actually exactly what it is
@@djmjay2 You'll notice it's typically the manufacturers that have free maintenance for x number of years that spec these absurd oil change intervals. Take bmw for example, interval used to be around 10k and the year they started doing 3 year free maintenance they upped it to 15k
I own a hotshot trucking company and regularly exceed the recommended oil change reminders on my 3500 ram Cummins. Had several go over 500,000 miles through the years and these trucks work hard pulling loads exceeding 20,000 lbs!
Thank you for your wonderful content. I enjoy learning so much from your videos and explanations.

Oh yeah, it was the oil change, silly me
World hunger has been solved and poverty has been eradicated.
This is genius.
Another note... foam inhibitors. Usually in the form of polymethylsiloxane or methyl acrylates, these additives are the most susceptible to additive clash. Different anti-foaming chemistry can be equally effective on their own but cancel each other out if blended. This is usually a problem with aftermarket oil supplements. It's a common problem in racing engines where people are adding ZDDP supplements to a finished API oil to try to boost the wear protection and end up sacrificing the foaming and aeration control in the process. Then when oil temps start to shoot up, pressure drops, and bearings start overheating, cavitating, and spalling, they usually blame everything except their oil regiment.
interesting
If you send your oil off for testing at Blackstone they will run the viscosity and check the additive package, contaminants, and TBN (total base number). This allows you to see how much life you have left in your oil. TLDR you can often run your oil for a lot longer than the specification (the spec is somewhat arbitrary and factors like driving style -- a straight shot across the country on highway alone will often times leave the oil looking and testing like new). That being said, the cost of an oil test can be quite similar to the cost of an oil change.
Black stone made me about $1000. Long story short, car got totaled. Appraiser said it’s worth next to nothing because of the mileage, saying the motor is shot. We sent the Blackstone report showing it was in great condition. Appraisal came back $1000 higher. Best $45 I ever spent.
@@nasonguy So itll tell you how healthy thew engine in general still is? thats a very good thing to know.
@@dobber43 Blackstone analysis will tell you a few things. The contents of the oil (more wear metals is bad, more detergents/dispersants is generally a good thing, etc), and the physical qualities of the oil (is the viscosity still good? Could you have gone with a longer oil change interval, etc).
@NicholasAndre1...good reply. Blackstone suggested we continue just replacing the filter, suby, and running it to 12K....highway miles mostly. That is double what is supposedly the change interval.
@@darrellborland119 yeah especially if you burn a bit of oil and have to top it off half way through synthetic highway mileage should be fine. Although if you have to rotate the tires might be convenient to just do the oil change and have them inspect brakes etc.
Jason is a great teacher. Never boring. I never yohn when I listen to him. Great videos nice clear voice and no crappy music in the background.
Gonna debate a small point w/ you.
A ‘Great’ teacher makes the un-understandable - understandable.
I opened this video simply wanting to know IF it’s the miles driven? Or the length of time in the engine? We have a low-mileage F150 that hasn’t had the oil changed in 2 years because it sits a lot in the garage. There’s only 950 miles on last oil change. But it’s been sitting in there over 2 years....
OK, so I got a LOT OF INFO from a Master’s level auto genius. In fact, TMI ! And I guess I generally get that it’s bad to run old, dirty oil - and that it hurts an engine. But I didn’t get my simple question answered in a simple understandable way.
@@boomer1954ful 67 years old and your just now trying to figure this out?? . I'm 62, and have known since my early 20s, if you don't drive it much, change it once a year.
Very good video as usual!
I manage the oil analysis for a company that sells lubricants (hydraulic, gear, engine, etc), and I have to say that especially for customers who have many trucks or tractors is extremely useful to perform analisys (it is also valid for other kind of equipment), cause you can avoid to change the lubricant too early or too late, saving money and time, and it happened also to find contaminants that indicate an incombent failure of a specific component, and reporting it, customer can prevent major damages to the equipment.

Been watching him since the early days of RUclips. We were saying the same thing back then.
Most current oils have removed or significantly reduced zinc content, as it raises problems with modern catalytic converters. It is a really important additive for small engines. Some small engine manufacturers like Kohler sell motor oil for their engines with zinc additives.
What's the replacement?
A great video. I. Going to send this to my wife and my 2nd oldest son. Change your oil on time. Stay safe brother 🙏.
Dope work brother
Interestingly, my previous understanding, and experience with diesel engine oil (specifically Rotella), was that the breakdown of viscosity modifiers was a much more important factor in oil degradation than oxidation, at least on time scales relevant to automotive oil changes. I used to do engine testing and have oil samples analyzed every 20 hours of operation or so. We would see substantial decreases in viscosity over the first couple hundred hours, IIRC. At which point it would level out rather a bit lower than the oil's spec'd viscosity. Sure if you put 30k miles on the oil you would expect to see oxidation thickening, but I don't know that that's all that important if you skipped one oil change. And that's the issue, low viscosity is generally a more immediate concern than high viscosity, as this reduces film thicknesses, causing heat, causing lower viscosity, causing reduced film thickness... causing metal-metal contact.
yeah jason is full of it.
Very cool! You should so do a video like this on automatic transmission fluid. I rather enjoy ur videos! And I like that u drive a subi!

Davey Bernard its no different than a manual trans really. Drop the pan to drain. And then there will be a fill bolt somewhere on top or the side along with a level check bolt. Bam job done. “Lifetime” fluid is a weird term. If the trans lasts 30k or 300k ok itself fluid it still was lifetime. That was the tran’s life.

You don’t really need to change oil if your car leaks so much that you’re adding a quart every week amirite?
Need to change your seals at every oil change in that case
Agreed
@Dangerous One
haha.. yeah probably right, if it doesn't build up some sh*t somewhere then you only have to replace oil filter now n then. I always check oil quality by rubbing a small amount between my fingers. You can feel difference from good vs bad lubrication. The color also shows quite clearly when the fluid is bad (=dark brown/black). No need to send to any lab.
As long as it's synthetic
still need to in order to change out the contaminants that formed. they don't just disappear with the oil.
Oil schedules are set for people who load their engines when they drive. Low load long runs are some of the best driving you can do for your engine. Short runs and stopping in between are quite a bit harder on the engine and performance driving even more again. I worry less about my wife’s Yaris service wise than I have any previous vehicle she has owned. Working out the length to which you can run your oil without changing requires an understanding of the load that the car is under most frequently and the general wear factors. If you can then you won’t panic at passing the set change time/distance between ….
Thank You for this thorough explaination. Very Much Appreciated! Regards JB
I notice with my car and a lot of trucks I have driven that when the oil is getting due, it usually needs a top up which adds a bit of fresh additives and of course adds to the volume circulating. Not a metric I would rely on but a handy rule of thumb. The type of driving is also important too. I drive a 70 kilometre round trip for work on expressway driving which is much kinder than stop go driving. Probably could go over the distance but better safe than sorry if you don't get your oil tested to know how much life you really have left.
You have taught me more than my dad has in the past 22 years. I found out about your channel two weeks ago. I love these types of videos.

This concentrates exclusively on time not mileage , a bit dissapointed that real mileage examples with data was not used , so if you have an occaisonal car that does low milage do you change when the milage is up or at a regular interval when its had little work to do ..?
R Warner,
"This concentrates exclusively on time not mileage, ..." Did you mean that the other way around? Seems to me that all of the detrimental effects on oil he describes here are a function of the car being driven (like oil being burned) rather than what makes it go bad over time when not driven much.
The owner's manual for my car says (for "normal" driving) to change the oil after 7,500 mile or 12 months, WHICHEVER COMES FIRST.
Yes I probably didnt state it clearly enough , I think he was describing excess milage but kept saying late changing the oil . I believe that the oil degradation is almost exclusively a function of mileage not the duration its been in the sump 1, but would havr been good to cover both .
He usually has data to back it up but not this time ..how far beyond recommended mileage before those effects become significant and what about long life oils ?
When I was flying, the adage was “gasoline and oil are the cheapest things you put into an engine”.
Bear in mind that a typical Aircraft Engine rebuild is north of $25,000.
Bram Moerman - Yes, true, but that is just a small 4 cylinder motor. Bigger = way bigger bucks...
Yes, inflation is everywhere.
still cheaper than porsche ;
Remember about 50 years ago saw some AeroFrantz filters on crop dusters. They were FAA approved and used 2 ply facial quality bathroom tissue. Don't know anything about aircraft engines but know clean oil is better than dirty oil.
Thats the low end. I went to an engine overhaul shop near lunken in Cincinnati and 25k was easily spent on the little 4-cyl lycoming and continental engines.
I work in an aviation engine shop and can confirm the prices are excessive. To just get a replacement camshaft for a 8 cyl Lycoming 720 costs about $8,000 our price (some markup for customer).
Sir... you are the future! Thank you!
Thank you for your explanation & informative videos!
Went about 2000km over my scheduled oil change interval (15000km) due to mechanics being booked out leading up to xmas and then closed for 2 weeks, just as I had overseas visitors and had to do a lot of driving. The engine was noticeably louder during idle as well as under load, and when the oil was changed, the quietness then uncovered diff noise (diff oil not changed in 93000km). Significant noise reduction now that the diff oil has been changed, however I wouldn't have said the car was noisy before. The change in sound just creeps up on you.
I have always doubled the oil change recommendations and never had an issue on any vehicle I have had .
Glenna Barry I never had issue with my vehicles by sticking to manufacturer’s recommendation of oil change and I am not polluting environment by doing unnecessary oil changes.
@@olasek7972 if I am reading the comment correctly doubled means two times i.e. if the manufacturer says 5,000 miles he goes 10,000 miles. But I agree, my motorcycle has oil change intervals of 7,500 miles and some folks change every 3,000 and it is so unnecessary.
Stephen Smith you could be right, “double” could have two different meanings here, now I am not even sure what he meant.
Excellent explanation. As always...
Amazing analysis, thank you!
I usually change now when recommended, however when I was younger and had little money, I had a 1985 Nissan minitruck. I used synthetic oil, (Mobil 1) and only changed the oil when it went down a quart (liter). That was about every 40,000kms. At around 350,000kms, I had to change a valve cover gasket, and when I took the cover off, I expected to to see a bunch of sludge, but it was clean as a new engine. The compression was also still very high, around 180 psi. I ended up giving it to my ex, and she drove it to 460,000 kms, and then got a newer vehicle, but the engine was still running like a top at even with all that mileage.. The point I am making, is that if you are using a quality oil, especially synthetic, I really don't think that running a couple thousand kms or miles over the recommended interval will make all that much of a difference in the long term.
It most likely won't as long as the extra distance is within reasonable limits. Also how it's been run matters.
Interesting. I wonder what kind of driving did you do. Motorway or urban? Probably mostly long drives from the high mileage
Same experience here, I kept postponing the oil change on a Corolla because the oil remained clear. At 40,000 km it was darker than new but not all that much. Synthetic oil doesn't break down and deteriorate like conventional oil.
Michael Walsh : I was commuting to Toronto, so it was a mix of highway and.a lot of jammed up stop and go. The worst kind to an engine. 1 hour 40 minutes each way.
Even much more. Reinforced filter is important.
Just a heads up, the winter SAE number on the oil is not the cold viscosity, but rather the flow characteristics in cold weather. A 5w-30 oil flows like a 5w oil when cold, but may have a higher viscosity than 30
Great show as always
Wanted to know what time it was...was taught how to build a watch. Thank you. Great video as always.
Jason I would like to have you talk about the new line of. Engine oil coming out for Di engines that the SAE is testing
Those oils have been out for many years. There's nothing trick to it. Calcium and sodium based additives increase low speed pre-ignition (LSPI) in DI engines so oils formulated with DI engines in mind (API SN Plus rating and/or Dexos 1 Gen 2 rating) have no sodium detergents, less calcium detergents, and (typically) more magnesium detergents since magnesium is found to be LSPI neutral. Other than that, the formulas aren't much different.
Hello EE, thanks for the great videos! What are your feelings on oil additives such as BG MOA and others? Are they necessary, do they actually benefit the engine in some way? Are they worth it?
If your car runs well, absolutely not. Use a nice oil filter preferably OE, the proper spec and the proper intervals and that's it! Additive packages already exist in the fresh oil
I love this guy str8 to the point rite off the bat no hesitation …. 💯 good video bro thanks for the info !!!!
I like the new computer calculated service intervals, basically the more you rendline your car more sooner your service will be. I have a MB Vito Furgon, the new one from 2018 and it has that system. Super cool
You can have your oil analyzed and decide if your oil change intervals are adequate. I use synthetic oil and change the oil every 10k or so. My car has 227k, and the engine is running just fine.
Most people are on the WIGATI (when I get around to it) maintenance program!
Excellent! Thanks Jason!
Very informative and great presentation.... knowledge is power and thank you for sharing your knowledge with us...
Thanks for the useful content. What about cars that are parked most of the time and used for short intervals. The Oil is recommended to change after 10,000KM but actually, this car makes this distance in about 2-3 years. Is there also a time interval after which the oil and other parts should be replaced no matter the mileage?
What's recommended in that case for the Oil, filter, and other spare parts replacement.
Great question 3k mi or 3 months witch ever comes first I herd
Unless you are 'abusing' the oil (high temps for example) it's more important to change filters and keep the oil level up. Yes oxidized oil should be changed, but today's high quality synthetic oils hold up really well to typical driving. More often than not, oil still capable of protecting an engine is drained out and replaced.
Would be interested in seeing actual oil analysis at recommended oil change intervals
You do a great job with great info
Just consider how some trucking companies and me do oil service; use the best synthetic and change the filter at 8k and top off when necessary. You do a good job for those who do not know.
I got a 2001 Toyota Camry with 300k miles, does not burn a drop of oil.
I use cheapest oil, but religiously change it every 3k miles or 3 months.
Parked and changes on the same spot on my driveway by myself for the past 10 years. All fluid changes according to the owners manual.
I think most issues are either lack of maintenance or neglect. The other 10% is bad luck lol
You should do a video on aftermarket air filters like K&N and AFE. A lot of people are convinced that even with lower surface area and bigger pores to make up for it, they still filter just as well as OEM paper filters.
Why does Jason have to do all the work making videos? Are you not already convinced which are the best oil filters?
Very informative & helpful video 👍🏻👍🏻
Keep up the good job!
A mechanic in Houston, TX posted a video of what an engine looks like when the oil hasn't been changed. Back in the late '90s and early 2000s, Toyota did have a problem of oil sludge. This is another important reason to change your oil regularly. If you have low mileage - driving your car less then 5000 miles a year, then changing your oil once a year will suffice.
I have a 1998 Explorer that I drive about 1,000-2,000mi per year and only change my oil once in each year. Seems to be ok but considering how my timing chain cassettes were already going out I couldn't tell if I was hurting the motor or not....
Great info, thanks. Two questions:
1. Does the oil level matter, as long as it's within the normal range, or is it best to keep it at the high point?
2. Is there a significant benefit to replacing oil sooner than what is recommended? At what point do you change yours?
Always keep it to the Full Mark .
No
No
Above minimum mark is fine, whenever mine hits the minimum I just refill it to full
And going shorter than the normal interval is pointless, the oil is designed to last a certain amount of time, just not too long. Check your owners manual, but general rule of thumb is 5-7k for synthetic and 3k for conventional. Newer cars can go longer though.
Great video. I love all your videos. Perfect intro for that person looking for an excuse not to change the oil 😅
I've certainly watched many of your videos, thanks for all your hard work. I thot of a topic you could investigate, emissions. Both gas and diesel, why, whats good and whats bad... etc.
Me, at 1:01 AM: "Ahhh, finally! I've been waiting for so long another video of EE with a whiteboard and a lot of math involved"
Customer: I need an oil change, my oil change light is coming on again when I go around corners and hit the brakes hard. Me 🙄
Is that low oil? Or am i taking this wrong?
Potatoe Salech yes potato that’s low oil
@@jeffclark5024 or it the oil presser sensor didn't read
That's how my friend used to check his oil on his Dodge Stealth. Needles to say, he had to replace the engine. He had better luck with a Nissan Maxima.
But he still used his method. Car went 300k.
i was changing my engine in my 03 civic, i had a blown connecting rod, so right before doing the job, i redlined it to have fun and eventually the oil light came on, when it did i stoped and checked the oil, their was none left, then i made research, on civics, it only turns on when theirs only but a few drops left
Very thorough!
Nice explanation as usual.. thanks
Love your videos. Please cover DEF, DPF, and emissions in Semies. I used to be an Owner Operator
I love this video, it's like Blue's Clues for automotive technology. 😂
You know what we need! Our handy dandy notebook!
My 2010 Kia 2.0 has been on fully syn Shell 5w40 helix ultra from Day 1, now at 240000km still clean running with zero leaks.. Zero topup needed, i change the oil every 9 months or 15000km and the used oil comes out clean. Manufacturer recommendation Is every 10000km 6 months. I'm in tropical Malaysia
Have you done, or would you be able to do a video on CVTs? What makes them different? Do you recommend changing the fluid? If so how often? Etc.
I use used oil to light my BBQ grill. Gives my burgers an unique flavor that I like (adds carbon and iron). I live for the day (probably not many left). ;-)
This made me feel uncomfortable in a new way.
Thanks, this helped. I suggest a subtitle: "Why you're thinking about getting an EV"
people who think EVs dont need maintenance should take the bus or stay away from the road
@@anon9019 They need considerably LESS maintenance, but yes, not none.
Very detailed info. Thank you so much, translated to be understood even on nerds like me.
Very informative. I have stopped using conventional oils, full synthetic only. I seem to see less sludge in the valve cover when I am adding or changing oil. I thought the issue with conventional oils was change-scission (viscosity reduction) due to shearing. (Regularly get 200k miles on my cars. One is over 300k miles...still in the family.) I seem to remember that Consumer Reports did a big test on motor oils in the '80s that utilized a diesel injector to spray hot oil under test to causing shearing. It was illuminating, as almost every oil did not stay in viscosity range. Can't recall if Mobil1 was the winner.
Also, if you get your oil tested, as fleet operators do, they return a result called "TBN" (Total Base Number) which measures the oil's remaining ability to neutralize organic acids produced by combustion (Carboxylic Acid typically). At issue would be excessive idling experienced in many petrel fleet engines and also diesel OTR trucks that idle all night long. This operation is considered severe duty for that reason. Low oil temp does not allow the off-gassing of the water that is trapped in the oil (remembering that water is one of the main products of combustion :)) Comments regarding TBN?
In the 1990's Motor Trend magazine did a oil study involving New York City taxi's, vehicles that put a lot of miles on quick, so the results came in quick. They change oil on one set of cabs at 3,000 mile, another set of cabs at 6,000 miles, and then 9,000 miles, and lastly, 12,000 miles. At 100,000 miles they tore these engines down, and found less that 5% wear difference across all examples. Results were clear, oil changes at 3-6,000 miles was a big waste of money. 9-12,000 miles seemed to work just as well.
Yea i was gonna say. The high oil changes was made because they wanted to sell more oil. But I've ran cars without oil change for a year and half. I dont let the oil run low of course but I have realized changing oil very early your wasting your oil
This was a great study they did. Yes there May be a benefit of changing more often theoretically, but what is the real world effect? If a significant real world affect isn’t seen until 3 million miles, then it doesn’t matter much cause the car has other parts that won’t last that long. Or if the effect is 1mpg then you can see if the cost outweighs the benefit by doing some simple math.
Here in the EU vehicles are on 10,000+, some as high as 18,000-20,000 and we're getting 150,000-200,000 miles without issue and usually it is the bodywork that fails before the engine.
@@conorturton 10,000 km is roughly 6,250 mi, so more or less the same.
@@anonymousinc6330 they ment 10 000 miles. Otherwise here it starts from 15 000km to 30 000km. From 12 to 24 months whatever goes first. This depends on manufacturers, models, model year, etc.
Very informative, as always EE. A question in related vein: I drive my car very, very rarely. It usually sits for a week, very often two, sometimes more. It still runs very well (it's 7 yo) and oil changes come every 5-6k but I often wondered if sitting in the parking lot for 2 weeks, do I have any lubrication left at startup. So would it be a good idea to have it run for a few minutes every few days.
Waiting about 15-30 seconds is enough to get oil to circulate in the engine. If you can drive it up to operating temperature every few days that is good, but just turning the ignition on and letting it idle for a few minutes will actually cause more damage (more time spent with cold oil, idling doesn't effectively warm up the engine and you will get condensation which will contribute to oil oxidisation).
@@stephensmith2027 that's why we don't have to let the car idle to get to operation temperature, that's overkill. What we HAVE to do is drive it. Also, driving a car at least 30 minutes per week is enough to maintain the engine correctly.
Great explanation.
Another brilliant demonstration and use of white board to explain a motor engine inner workings..
