Will Annual Oil Change Damage Your Car? Let's find out!
HTML-код
- Опубликовано: 5 фев 2025
- Does waiting a full year to change motor oil damage your car if it has not yet reached the oil change interval for miles or hours? Do you need to change oil sooner than a year if your car has not yet reached the recommended miles for an oil change? Two engines with oil over one year in the crankcase tested to determine if the oil was still good or if it had become corrosive. Oil tested by Project Farm and by an independent oil testing lab for moisture content, total base number, contamination, acidity, and overall condition. The oil in both engines had not yet reached the oil change interval for miles/hours. Recommend following the manufacturers oil change interval guidelines for miles and length of time for your car.

Hey Todd! love the videos! I was wondering if you could test Kirkland Signatures new 15W40 Diesel engine oil! See how it compares to Rotella T4!
Can you test semi synthetic oils
T6 vs Schaefers please. Which is better ?
I wonder if you can do a test for PERTUA Engine oil and metal treatment and check the claims of what Pertua do to the engine.

Great test! My dealership was having me change oil every 3k, but new dealership says once a year. Im a recent widow (my husband got 439,000 out of his 95 Dakota and did all the maintenance and repairs on our vehicles) and have to rely on yt and research. I appreciate your work and attention to detail.
Thanks and you are welcome! I extend to you my deepest sympathy on the loss of your husband.
You should still change it every 3,000 miles if it is conventional oil, or 5,000 if synthetic, but you don’t need to change it every 3-6 months. Still change it based on operating miles. Dealerships will tell you more miles, but more than about 5,000 can cause damage, longer term.
@@Tir220 THANK YOU! PREACH!!!!!! IM TIRED OF THE ONCE PER YEAR RECOMMENDATIONS
I do agree on determining the oil change based on the driven miles. The only thing more accurate would be to have an hour meter! I think that the 1 year thing is probably a fairly good estimate on the milage on a regular daily driver in a year being close to the 5000km mark. Just guessing at stuff!
jenny I am a mechanic, it will not hurt your car to do it at 3,000 but if it is a newer car it is wasteful cars, like people need more care as they age, an average car will be ok with 7,000 miles until you hit about 70,000 miles then you should shorten it, over 100,000, 3,000 miles will keep it going, also the more miles you have, go up on the viscosity
Thank you. The unbiased information that you provide is extremely rare. I really appreciate everything you do.

@@ProjectFarm interesting facts about leading oils, must see!!! ruclips.net/video/g7Tc-YkJRxk/видео.html
@@ProjectFarm Could you do a video comparing 0w20 to 5w30 oils? The Toyota 3UR-FE V8 specs anywhere from 0w20 to 20w50 depending on country. The US specs only 0w20 while the Middle East and Australia can use 5w30.
@@Joe333x Maybe the variation is due to ambient temperature? I understand parts of the U.S. sees temperatures below freezing. In Australia, thats very rare. However we often have high temperatures, so we have to deal with that.
I' ve always believed the " once a year regardless of milage" oil change was a way just to sell more oil. I change the oil based on mileage or operating hours on my vehicles and tractors. All have had long lives with no wear problems. So many people are throwing away good oil thinking they are prolonging the life of their vehicles. You proved them wrong. Thanks for the test.
Thanks for the feedback
My car manual says that but I think that's to make you check your oil and to cover the car manufacturer's butt.
@@LiveType Not really , it tends to clump after some time.
Left my Shell Rotella T6 eight years and came back to find the crank had filled with gas, displacing the oil. Crap. Stuff like this happens when operating over the year too, so it really depends.
Changing your oil only once per year is okay if you don't drive a vehicle. For those of us who do, please don't let what this person thinks dictate your oil change schedule. You change it when the oil is spent. You can see by the color, viscosity and texture. Dark brown, non-see through, slight smell. Change it. Don't need to look at the odometer. That oil will stay tan and see through for a few decades if left in the garage, so the amount of time matters little. Each engine is different. Oil types are different. Some have older seals that allow blow by and burning of oil will require more frequent oil changes due to the amount of particulate in the oil. Once that particulate count gets too high, the viscosity decreases, and that same amount of oil is not as effective. It's easy to tell in 2 steps. 1. Find oil dipstick 2. if oil is black, change it.
I really like your testing style... no assumptions, no personal years of experience, no nonsense...
Like always no beating around a bush... pure a simple hard core testing....
Glad to hear! Thanks for watching.
I have been a member since the near begging of this channel. Love the genuine honestly in all the tests. Great channel.
Thanks and you are welcome!
It's been a year video, but still helps unanswered question for many. Totally respect your effort and time doing this experiment. Hands down the best auto tester channel
Good to know that for retired people like me that don't drive much (under 4000 miles a year), that using high quality full synthetic oil, the annual oil change is good enough. Also good to know that if you go 13 months, say, vs. 12 on occasion between oil changes, no big deal with low mileage.
Thanks for the energetic testing efforts you do. Subscribing and thumbs up.
You are welcome! Thanks for watching and subscribing!
My wife's car(Synthetic) has 5000km in a year, that's 3,125mi. Do you think it's time to have oil changed?
@@JesseMgala it's generally a good idea but it depends if you are in a humid climate, if the humidity wasn't terrible in the last year just check to see if the oil level dropped. If it dropped I'd just change it but if nothing was lost you could go a bit longer I think. I usually change one of my vehicles I dont drive much yearly due to the high humidity even though its parked in a garage just to be on the safe side and because I'm picky.
@@VintageCars999 We're in Toronto, Canada.
Do a Blackstone oil test. It's cheap. The report comes back with advice about if going longer is better. You might find that 2-year changes are safe.
Someone actually analyzed a collection of anonymized Blackstone data and found that frequent oil changes actually produced more wear than than infrequent (until you reach the point the oil is so degraded that it begins to cause wear). The person doing this analysis wasn't sure why that pattern of new-oil wear was in the data. It could have been new oil dislodging contaminants which caused wear before being trapped in the filter? It was interesting that "more" isn't better that way. Changing every 3 months (which some "severe" schedules call for even when low miles) was worse than going a full year.
A car's warranty is one thing to keep in mind. If it calls short-trip driving "severe," and you find through your own oil analysis that you can go 12-18 months between changes without any signs of degradation... you could find yourself in a tough spot if you have a warranty claim. You'd think the analysis reports would stand as proof. But, some car makers will use anything to get out of a claim. So, saving a little on oil changes might not be worth the fight, and voiding a warranty.
Absolutely fantastic testing! Hard to dispute the lab results. That truck is in great shape for its age! I like that oil filter cutting tool.
Thank you very much! The truck is my baby, although I do work the truck hard when its time to go to work. By the way, you've got amazing content on your channel!
I think the tool could have been a pipe cutter
@@levivaughan3434 it’s a special filer cutting tool.
I use Airwolf Filter Corp cutter every 50hr on aircraft filters.
Open filter media and run a magnet across the folds while doing a close visual.
That and trending a spent oil lab analysis will give you a good idea how things are functioning.
This was such good news to hear about oils being good after 12 months. My fiancé drives a 2004 Toyota Camry only about 3000 miles every year. It is driven at least once or twice a month so the oil gets up to temp periodically. We keep the battery charged with a CTEK charger as well. I didn't do the oil change for nearly 21 months when we hit 5000 miles and the maintenance required light came on. This tells me the oil will be good for the time that we drive between oil changes. We haven't experienced any adverse issues so far and use high quality synthetic oil. Thank you Project Farm for putting out an incredible and informative video.
Thanks and you are welcome!
I have a Mustang V8 that's rarely driven. I change the motor oil once every other year. No problems.
I still own a Toyota Tacoma 2004 with 300 thousand miles on its and still running around, no problem with engine yet, I always take it to the dealer and the dealer put a new chassis on it for free,

Todd, I couldn't believe my eyes when I saw this video today, because this is the question I asked you in the comments of a previous video! Thank you so much you made this video.
This is Exactly like my case at the moment - my car oil is full synthetic at 1900 miles (3000 km) and is like yours - 17 months old. I change my oil myself because I find it satisfying experience and planned to change it in the spring when it is warmer. One day I spent a day researching the Internet whether I should change my oil around the one year mark but I could not find anything - everybody said that it should be changed once a year (for the synthetic) because it was written on the bottle... Also in the car forums was popular the opinion that the oil no longer has the lubrication properties, that it contains water/moisture, fuel and it is bad for the engine. However these were all peoples assumptions and absolutely zero tests, experiments, or facts, only opinions or writings from oil bottles. So knowing this rumors and legends I started to avoid driving my car because I false knew the engine oil is bad and I am going to damage the engine life.
I drive the car couple of times a month and reaching operating temperature every time. Yes, I knew that the engine oil is not good as new, that the oil condition depends whether is city or highway driven and on other conditions. However until now I haven't seen any tests to show whether such low mile oil will ruin the engine if passed the annual change mark.
So thank you so much Todd, that you myth busted this the one year mark for a low miles oil and brought light to this topic! With hand on my heart I am saying that this is one of the Best channels on youtube! Thank you and Merry Christmas!
Thank you very much! Merry Christmas!
... you've confirmed what I've thought for many years... 'change your car oil every year regardless'... what a load of old tosh... PF, you really are providing an excellent service for all of us with these in great in depth tests... keep up the good work, cheers!
if you have a paper end cap filter you want to change it at lest twice a year other wise you will have old filter sludge in your oil system..
First time I have watched one of your videos and have to say I'm impressed by the level of thoroughness you install in your tests. Very informative. Thank you
Thanks and you are welcome!
This video was years in the making... thats why PF is awesome!

I have over a dozen cars, many that see less than 1k miles a year and always go back and forth how often the oil needs changed. I’ve been looking for a test like this for years. Excellent video and very informative. Thanks for the great video!
Thank you for the feedback
Same with me, I'll change every two years regardless of miles on oil.
I think I’m going to start going every two years now. When I go to do my annual oil change, the oil always looks new and feels like a waste
@@mikedubasak5280 Thats BS, fresh oil will change its color from honey-yellow to brownish in a couple 100 miles. You can see it in the video, when he cooked the oils. So dont tell us, your oil looks like new... Youve probably never seen it yourself...
That seemed like a dicky and unnecessary comment, especially on Christmas...
He cooked the oil at 400 degrees to replicate extreme conditions, oil in a motor is typically right around 250 degrees. Color is a little subjective, especially when your looking at it on a dipstick. The only oil that is black right away (at least in my experience) is in an old ford 7.3 diesel truck I have. In a well maintained good running motor, oil doesn’t change very quick, especially in newer cars. Again, in my situation, oil I’m looking at oil less than 1000 miles in a car that is sitting in a garage. Maybe if a motor is really tired, it would be black pretty quick. Again, just sharing my experiences as a mechanic of 15 years.
I bought a new Ford Ranger in '03. 3.0 V-6 engine. When the warranty was up, I put it on an annual oil change. Mobil 1 High Mileage 5W/30 and Motorcraft filter. I would average 10 to 12 K. per year when it was my daily driver to work. The truck has 196K on it now. I recently replaced a leaking valve cover gasket and the valve springs, head, and valve cover were spotless. I have been retired for years and the yearly mileage has declined. But still once a year on everything I own. I love your videos! Very good unbiased and useful info.
Thanks! Thanks for sharing.
I don't know how you have time to do all of these amazing videos but I'm glad you do. Keep them coming. I've learned so much from you. Thank you!

As a 25+ year mechanic, I really appreciate your comment about letting your engine come up to operating temp once a month to disperse any moisture. I have long believed that "time intervals" for oil changes were a joke/propaganda. I have always advised my family & customers to go by hours/mileage as long as the engine was operated at normal operating temp every 4 to 5 weeks.
Thank you very much and great advice!
I can not understand the term "normal operating temp" i have a new VW PASSAT that have an oil temp reading (not the water coolent temp) in the instrument cluster. If i drive gently for long distances it average 97 in summser and 92 in winter. If driven (reved) little harder in sport mode it reach 102 in summer. So my question is: should I bring the oil temp above 100 centigrade (boiling temp) or just the max temp of a gentle long run? They are way different temp from each other. Thank you
@@TubesWidener oil does not boil at 100 C. Water does at sea level and under certain barometric pressure.your oil should be fine upto an even higher C. Check oil manufacturer data.

@@TubesWidener ...then normal operating temp. for your car is approx. 95 Celsius on the instrument gauge (obviously the sensor's position is the reason why it is so low) so use that value.
@@solkim133 But it's water that must evaporate from the oil. Obviously the oil in his Passat gets much hotter than 100 Celsius, I don't know where the "German Engineers" placed the oil temp. sensor to read that low. I drove an Audi years back and the oil temp. gauge was at over 150 Celsius.

I am a retired Heavy Mechanic, Used to work for Greyhound Bus lines in The Calgary Alberta shop [500 buses] we began testing synthetic oils on
Select Buses in 1978, the wintertime in Calgary would require the Buses to be running 24hours a day, even when parked, due to extreme freezing temps., as you can imagine, these buses would go through Extreme duty most of their service life.
What we found through much testing and Laboratory back up, The Oil did not break down at service intervals. The Filtration was the Issue.
We found that Changing the filters [oil and Air} on a more frequent basis, e.g. Skip every other oil change but change out Filters, was giving Satisfactory results. Whether it was Natural or Synthetic did not matter.
End result: Change your filters more often, and don't worry about the Oil as much, since filtration is the key.
I have always run my vehicles on this method ever since and have never suffered any negative consequences.
Kinda makes you think, Why the service manuals instruct us to change the oil every XXX Miles or Klms.
So save your Money on Oil, and Change your Filters Often. Thanks for all your Vids, And i wish you and yours, the very best of the season.

Amsoil does not have brand specs codes on it's packaging, why not.

Back in the early 70s a buddy had an old Chevy van from the early 60s and that is exactly what he used to do.
Fun story. I work as a parts salesman and an old timer would make the trip to the store every 6 months or so to pick up parts and a lot of oil for his shop and haul it back up north in his late 90s f150. He overheard us talking about needing an oil change and mentioned that hes never changed his oil in his truck for the last 15 years. I asked him to elaborate and he said that he drills small holes in the bottom of the oil filter to slowly drain out oil and he tops it up every few days so he always has fresh oil. I laughed thinking it was a joke and the other guy working with me has known the older gentleman for 30+ years assured me that hes telling the truth. So after the old guy pays up and left i took a look where he was parked and sure enough there was a little bit of fresh oil on the ground. seems crazy to me but that truck has made thousands of kilometers in terrible northern road conditions and weather without ever changing the filter or oil.

Thank you! I'm putting less than 10K miles on my truck per year as I work from home. I was wondering about the 1 year limit for oil that I've heard about. Glad to see it is a myth. I always use pure synthetic. Mileage is another issue, but with modern metallurgy and lubricants I believe it safe to say that the 3K mileage limit is a myth.
Thanks for the feedback.
3K mi. oil changes are from decades ago, before synthetic oils were available. Synthetics go 10K mi.
@@joevarga5982 highly depends on the car and driver. No oil is going to last long in a small turbo engine with a 3.5 liter capacity you redline all the time
@@gigel99324 "No oil is going to last long in a small turbo engine with a 3.5 liter capacity you redline all the time"
Sooo... you cherry-pick a severe-duty application to prove that I'm wrong? Lol.
The traditional 3,000 oil change interval was STANDARD, GENERAL-PURPOSE advice for EVERYDAY typical use for AVERAGE people from back in the day. OF COURSE you'd have change more frequently for severe duty applications.
@@joevarga5982 I'm beginning to agree. Scotty says change every 3k, but I've got 5k on my oil now and it's still clean. Not spotless, but can clearly see the dipstick. Do you personally go 10k on synthetic?
You have the most interesting and informative channel on RUclips. Thank you!

@@captainamericaamerica8090 well deserved!!!!
My dad was a truck driver for 55 years before he retired a few years ago. He had driven just about every truck, engine combination you can imagine. The last truck he drove he was an owner operator and he would only put Rotella in it. I remember him saying that of all the oils he ever used it held the best oil pressure right up until the time it was time to change it. The truck had a 60 series Detroit in it and at the time of retirement it had 2,400,000 miles on it with two in frames one each at 1,000,000 miles. The truck was new when he purchased it so the engine had only ever seen Rotella.
Thank you for sharing!
2.4 million miles, thats insane.
@@lunathecutest6652 Little bit. Feel for the guy.
Really good to know, since retirement, I only put 1,000 - 2,000 miles per year on my vehicles and now I can change the oil once every two years with a premium oil filter installed. Thanks again for your great videos !!!
You are welcome!
I'm doing my 67 Nova 283 oil and filter change after 4 yrs of use :) I drive it like 20 times a yr around my area.
@@williamcrazylacyfurmage9953 I left oil in a parked Integra for 5 years. Ran great.
@@edwil111 quality of oil has nothing to do with how a vehicle runs.
I change oil on my four small engines every other year. They range in age from 30 to 40 years old and still run well when needed. I’ve had issues but not with parts contacting oil. Thanks for your good work!
You are welcome!
Sounds like thats more of a testament to the build quality of the engines, rather than the oil. That or they have extremely low hours and light use. Ask an actual professional landscaper, builder, etc. NOTHING lasts that long under regular heavy use.
@@Doomzdayxx I'm not a profession so you raise a good point. My use is limited to less than 200 hours per year for the most used engine.
So straightforward, no BS, gosh this channel is gold!
Keep up the good work!
Thank you for the feedback!
Definitely gotta be one of the greatest RUclips channels here. Thanks again for sharing this fantastic information!
Thanks so much!
Just changed the Honda Accord V6 after 2 years and 5,000 miles. The maintenance minder said it still had 40% life. I only changed it because of always hearing about it has to be changed every 6 months even if you don't reach the mileage limit. I never believed that but was getting paranoid with it goin on 2 years. Now I know better. Thanks for confirming what I always suspected. Didn't know about the running at least once/month to get it up to operating temp. Good to know!
Thanks!
Your dodge is a gem! Low miles 12v cummins are very difficult to find.
Thank you
Rust free are less common. I see 5 yr old dodges with rotten out rockers.
Most of them are beet all the Hell by high school kids
Man that thing is a beaut!! 12v 5.9L, legendary engine.
The cummins engines are the best quality part of those trucks. The rest ... is Dodge.
I used T6 in my 2004 jeep grand cherokee for the first time a month ago, based on recommendations from a jeep forum, I guess they were right and you proved it! It actually increased my gas mileage by 3 miles per gallon and is a quieter motor. Merry Christmas, Sir, may your next year be fun and good. Amen.
Thank you for the feedback
So what oil were you running before? Same viscosity? Thanks.
@@melrobinson6919 10w30, castroil.
@@gristlevonraben Thanks. I'm going to try T6 in my 01 7.3 Powerstroke next oil change since this vid indicates it is slightly superior to the Chev Delo Full Syn I've been using.
@@melrobinson6919 awesome, just remember, they come only by the gallon, unless you are lucky enough to find a few quarts somewhere, so basically, you have to buy two gallons. They can be really cheap if you look around, though.
I've always followed once a year or every 7,500 miles, whichever is first. Part of it is doing your research and learning which cars/engines have known oil issues like sludging or oil burning. Those you want to change more often.
Thanks for the feedback.
When I was working in a highly stressful environment, I could not find the time/energy to change my oil for 2-1/2 years.
I drove my 1999, 6cyl, 4.0L Jeep XJ for 25,000 miles over that span of time on conventional oil. (If I remember correctly, I did add a couple of quarts during that run). Years later it's still running great, but I'm back on an annual conventional oil & filter change schedule.
Time is not relevant
@@hhjhj393 5k mile changes, and full synthetic Valvoline and a synthetic oil filter for me. From what I've heard, 5k is the most commonly recommended oil change interval, but 3k is if you do conventional oil, tow heavy objects, or drive the car very hard. (Also you're probably doing the smarter thing, because the more frequently the better! Lol.)
That's it guys. He said end of discussion. Lol. What a waste. Especially if you're using full synthetic .
When I was a young guy I worked for Shell Oil. There was an area in the operation where they would make engine oil and near by there was a container filling area. Since I was moved around quite a bit I got to see many aspects of the operation. In the filling area I saw the same product poured into different containers from 1 qt size to 55 gal drum size. The names of those products were SHELL, AGWAY, PENZOIL, QUAKER STATE, and a few others I can't remember just now.
Thanks for sharing.
I, too, have worked for a lubricant oil factory, and it's pretty amazing how much the different oils are the same.
Four different 5W-30s, but basically all of them identical. They might use one adative or the other, but the bases are the same. Speaking with the chemists there (QA chemists, not development chemists), they shrugged when I asked why I should choose the one oil over the other. All of the measured data were basically within each others' tolerances. They didn't want to say that they guarantee that they're the same, but they couldn't understand why an engine would suffer or last longer using the one 5W-30 over the other.
OEM-labels were also fun. They didn't claim to do something different than the base-label, but they always used more "creative" language to upsell you on their oil.... that's exactly identical to the other.
"Duff vs Duff Lite" moment
Bullshit....
@@joeybuddy96 don't forget duff dry! 😆
🏍Please do a Motorcycle/ATV engine oil showdown. You have done a lot of other things on this channel and was great but I really believe that this would be a popular topic in the RUclips community. Thanks and Merry Christmas!!👍🏻👍🏻👍🏻
Just run Rotella T6 and call it a day. That's literally what everyone else in this comment section does, including myself. You won't find a better oil for small engines with wet clutches.
Thank you for the video idea!
Project Farm Please include the Motul 7100 fully synthetic 10W40, for egoistic reasons :p
But really with all this positive feedback on rotella id really want to see wether a change of brand would be worth it!
@@JeremySchoeder Just as an fyi, a couple of years ago, Shell changed the formula for the Rotella line of oil, and added in some additional friction modifiers. This is not a good thing for motorcycle wet clutches. I only noticed this when my clutch started to slip, and I called my clutch company (Rekluse). They were the ones who used to say use the Rotella oil. They no longer recommend it due the the added friction modifiers. Still a great oil, just not for bike anymore.
Absolutely
Great video! This channels answers all the questions Google can't.
Thank you!
Awesome video ,Mr. Todd. No one seems to tackle the one year, low mileage situation. You did so and backed up what you said. I am satisfied now i can quit worrying about drawing out perfectly clean oil based on time, not miles Thanks. Enjoy watching you.
Thanks 👍
I've always done every other year. No issues so far. Every car has lasted forever.
I'm going to start changing my gas guzzlers at mileage instead of time since I don't drive them very often. Thanks, Todd!
Thanks for the feedback. You are welcome!
Changing your oil based on time is like a carpenter using his hands as a tape measure ..... it doesn't make much sense.
@@danaoberlander5754 I changed them both annually as I only average between 2k and 3k per vehicle. Knowing this, I can postpone the interval a bit longer and save a little money and elbow grease.
Just be careful about Moisture and age.
Yeah, I think as long as you're getting up to normal operating temps for several miles at a time, then you should be ok.
Your reviews and analysis segments are second to none sir. Thank you so much for so many comprehensive installments shared.
You are welcome!
My speculation has been confirmed! That clarification is invaluable! Many thanks and Merry Christmas to you and yours!
I'm always impressed by your incredible attention to detail. Your preparation, research, and choice of tests must take months !
It does take quite a few hours.
You've really done a great job of improving and expanding your videos over the last year.
Thank you very much!
I could watch these oil tests for hours. Nice to know when I still had my diesel trucks that the T6 was more than adequate.
Thank you very much!
I would love to see this kind of test about new vs old coolant! It's great how in depth your analysis always is.
Great suggestion!
Great video and suggestion. GM had some bad head gaskets on older models. Curious if acidic old antifreeze could have caused additional corrosion beyond the 5 year mark. Tough to establish a control across this time period, and compare head gasket corrosion.
They had Intake gasket problems maybe that's what u ment !!
Oil and steel are one thing, water and steel another. Then there is aluminum which has some wild reactions with chemicals. I would not keep antifreeze in there much beyond the recommended. I did that and the impeller on the water pump in my 85 Toyota pickup completed rotted out causing overheating.
I would like to see that too, I am a pro mechanic, I am advising people with cars that have a sealed cooling system that a coolant flush is not needed, would like to know if I am right
I'm going to stop at 0:34 and say what I should have said on another video of yours: that Dodge is sharp. I had an 02 just like that, 2500, Cummins, white, extended cab, long bed, bought new. Yours is in way cleaner shape than mine ever was after about 5 years.
Thanks!
There is no reason to dislike these videos. Thanks for the videos man.

Thank you!!
@@ProjectFarm Don't change a thing how you make these videos,very detailed and informative.Much appreciated.
Thanks a lot for this kind of testing! Trying to make sense of what is a good extended period before the next oil change and asking in forums is like asking them about their religion or politics. They already made their minds and sometimes not even facts based. After watching this I can confidently say is not going to be a problem to extend my oil change and car maintenance for 1 year, or even 2, given that I barely drive (less than 2000 miles per year) given my working from home situation and I don't have any money to burn. Thanks immensely for such a good job you do man!
You are welcome!
Damn, most comprehensive testing for the everyday consumer to understand without all that “sales” talk from these Oil Companies….
A most excellent dude…

Thank you! Thanks for the video idea.
Thanks for busting that myth. It never made sense to change the oil after a year when the shelf life of the oil is many many years.
Since you brought up oil bath air cleaners in the video: I've heard a LOT of old timers tell me oil bath was better at filtration than foam or paper media filters. Even heard one go as far to say that air filter companies launched a conspiracy to end oil baths just to sell more filters to farmers. Would be a cool test to see air flow and filtration efficiency between oil bath and other types of air filters.
Johndeere167 TV
Oil bath very good
paper air filters are very good at filtration and low restriction. oil filter baths are good at filtration but have much higher restriction. at least thats what i heard. i have seen many aftermarket air filters with dirt past the filter so i dont trust them (there are better ones out there however)
My john deere tractors I have from the 40s and 50s with no over hauls to my knowledge run good yet so oil bath has to be pretty good
Oil baths are great at catching coarse to moderate sized particulate, but not finer stuff. Older engines could deal with this, modern ones can't. The other big factor: turbochargers. Not a good idea to be sending oil vapour through them!
Oil bath filters are extremely good at keeping particulate out of your engine, especially for dust and dirt, which is a lot more common on farms than it is for your car to experience most likely.
I’ve never believed that there is something magical about a year’s time. In fact I’d love to see a 2.5 year test.
How does that make any sense ? Old engines that use would Explode way before 21/2 years! ,DUH !.
I change my truck's oil once a year. 4000 miles +/-. My RV only gets 1200 miles per year + 20 minute start and warm up monthly, so I change that every 3 years. Hasn't been a problem.
the collection of iron filings would start cutting into the internals of the engine.
@@bigfoot14eee99 start up and warming without driving is actually worse than not. Engine oil will take forever to warm up by idling and the amount of moisture is created gets in the exhaust and oil is scary. Just let the engine sit if you know you will not be driving the vehicle for at least 20-30 minutes.
@@Hathrandir Wrong, anything damaging will be collected by the engine filter. Plus we are talking about low hour low mile engine oil that sits not your daily short trip engine oil.
Every time I have a conversation with my friend he says that project farm has u well informed you bet keep up man
Nice! Thank you!
The most comprehensive answer to this question that I've seen. Excellent!
Thanks!
Fun Fact: You can clearly see in the video that the freezer is not set to -40degF but to -40degC.
Does not matter, as -40 is the only temperature where Degree C = Degree F
... agree. The race track was room temperature though which kinda screwed up the experiment...
@@f.d.6667 not really since the oils were all subjected to the same conditions.
@You Wish Would be okay with me.
@You Wish Because Rankine exists, clearly superior.
That's absolutely correct! At -40, Fahrenheit is the same as Centigrade.(Celsius) It's the only point of crossover on the thermometer.
Thank you for taking the time to put together these videos
Thank you and hope you enjoy the video!
Another fantastic video PF!! I’ll say it again, you have the best “man’s” channel on RUclips! Thanks for your work.
I got 210.000 mile on my 07 Ford freestyle with 3 oil changes. It don't leak it don't smoke and it hasn't turned thick. Never added any. I figured it would blow up 150.000 ago but. What a great car
Thanks for sharing.
I ran T6 in my 2006 CBR1000RR sport bike for years. It met the JASO MA rating as required by Honda. I had ZERO issues out of it and it was WAY cheaper than buying “motorcycle oil” by the Qt/L.
How many miles or kilometers on your CBR1000RR ?
Bang on buddy!
I have 47K, and I beat the shit of out it
What a crazy idea
Haplo59 i had like 27,000 mi when I got rid of it. It never smoked or used any oil at all.
2 hours watching your videos is perhaps more valuable than 2 years at MIT!
Thanks!
Todd, I really appreciate you sending the oils in this project out for official analysis, really makes things official. Nice review
Thanks!
If this guys' videos aren't the best thing on RUclips then I don't know what is.
And...often times I don't even understand half of what he's talking about.
Thanks!
Nice to see Shell oil products are still the top of the quality scale. My engineering class in 1994 did all of those tests, in our fuel chemistry course, including the ones you sent samples out to the lab to do, and came to the same results. Though we tested 10 different oil brands. Shell oils came out on top back then as well. (automotive, and aviation oils)
Good to know.
