    Thank you everyone for your comments. A number of people have asked for a data as a backup - but you have to remember that when it comes to predicting the durability of engines, the best way to do that is to take the engine apart. You will then clearly see the residue of the oil, condition of the inner components etc, and often times the condition of the engine itself does not correlate with the condition of the engine oil. So it is very deceiving - and dangerous - to assume that the engine is in good condition due to the good condition of the oil (through data and analysis). People like AMD from Car Care Nut, myself as an automotive engineer, and Mr. Takumi Kurosawa (Nissan GT-R engine leader) have all taken hundreds of engines apart and correlated the condition to the frequency and type of engine oil used. That's the best type of "data" and most accurate way to predict the engine condition (you can see it). Because I have taken apart hundreds and hundreds of automotive components apart, I know exactly what needs to be done to take care of automobile components and parts (not just engine), and my recommendations are based on these experiences. My two good friends AMD and Mr. Kurosawa will back me and support me as they have the same insights and ideas as in this video. I hope this helps you understand how I came up with my recommendations. At the end of the day, you are free to decide what to do based on your own experience and knowledge. I am simply sharing my insights based on 35 years of working with cars inside and out.

    Criteria A - Maximum Longevity (10 - 20 years) - 400,000 to 800,000 kms - or even longer. Change oil every 3,000 miles / 5,000 kms (6 months or earlier) Criteria B - Good Longevity (4 - 10 years) 160,000 to 400,000 kms Change oil every 5,000 miles / 8,000 kms or once a year or earlier - whichever comes first. Criteria C - Minimum Frequency (1 - 4 years) 40,000 - 160,000 kms People leasing or financing - who don't value longevity are recommended to follow the interval in their owners manual. Oil is able to keep its lubrication properties for a very long time. However, oil does get dirty and air and gas contaminants do get into the mixture Hence, why time is just as important as distance. I have huge respect for David, AMD from The Car Care Nut Channel and every mechanic who offers sensible advice. I live in Alberta, Canada and drive a Corolla Hybrid. I use a 4 month oil change interval. January - April May - August September - December I drive less than 15,000 kms annually (suburban 60% & highway 40%) Car has been rust-proofed and PPF added because the Alberta government has a ton of salt and sand added to the roads during the long winter months. The same applies to much of Canada. Toyota Corolla Sedan owners are advised to use 0W-16 oil... The weight is written on the oil cap. Criteria A - Phenomenal owners Criteria B - Fantastic owners Criteria C - Are not bothered about the longevity of their vehicles and less likely to maintain them - Zero respect. Thank you David & The Car Care Nut

    Are you trying to say that engine oil analysis does not give good information on the condition of the oil? You seem to also be saying you cannot tell how good the oil still is based on these tests? Are you saying this evidence, that you can also 'see' the actual test results, such as amount of contaminants, amount of wear particles, etc., somehow isn't reliable in predicting both whether the oil is still in good condition, or how much longer it will protect your engine? What actual evidence are you basing such a claim on? Long-haul truck companies routinely use these engine oil services to evaluate their oil's condition. Are they wasting their money?

    Thanks for this comment. There is something that has been bugging me with oil analysis. Like it might be missing some important things? I feel like we tripled the oil change mileage and at the same time added direct injection, turbos, and some questionable fuel with ethanol. I don't think oil capacity has increased much at all. Which all points to it being harder on the engine oil. I also feel that longer drain intervals will lead to more oil leaks but I have no proof of this. A major oil leak is almost as bad as an engine failure if it costs me $7000 to take the engine out and fix it. It just seems too easy to keep doing 5K oil changes instead of that. Thanks!

    @@garymaclean6903 Thank you for your comments, I appreciate you've taken the time to reply. However, you've completely misunderstood what I was trying to say. Yes the oil analysis will tell you the exact condition of the oil itself. However, at 3,000 or 5,000 miles, the oil would still be in good condition and would not have deteriorated enough to be a concern. Testing at these mileage would be waste of time. I would say beyond 7,000 miles the actual condition of the oil would matter. But unlike long-haul truck industry, you would not normally need to test the oil to see how long "you can keep driving" while keeping the same oil. You would normally try not to extend that much just to save a few quarts of oil - this might matter to long haul trucks but in automobiles, the cost of oil is cheap enough that you can change them out while the oil is still in good condition. I have taken engine apart, tested oil, tested various parts, and examined data to know this as a fact. You cannot compare long haul truck industry methods to modern consumer oriented automobiles where you don't need to prolong the oil until the oil is almost end of life.

    Great advice on how to make an engine last. Personally I don't care if I'm planning on keeping my vehicles basically forever or if I'm going to get rid of them every 50,000 miles. I'm going to treat every vehicle the same. I want to know when someone purchases something I bought new, broke in, and maintained, that they're going to buy something that could last another quarter million miles. I don't care if that person is a grandkid or some stranger I'll never meet. It's just the right thing to do.

    Agree 100% Much respect to the people who take care of their vehicles. Especially those who change their oil at frequent intervals as outlined by David and AMD from the Car Care Nut channel. Furthermore, the people who change their cars more frequently generally have higher incomes. So an extra oil change per year shouldn't put them in any financial hardships in the first place..

    @@JHKCF Basically every driver have different driving conditions which does not fit the ideal manufacturer oil change interval. You may have short trips like driving to work every day for 5 minutes which does not allow the engine to fully warm up. You may be a driver that does mostly city driving and that effects the engine oil. On the other hand you drive mainly highway driving which is good for the car. Then weather plays a part in which dusty and extreme freezing condition or very hot desert condition will effect engine oil wear. So the 10,000 mile oil change the manufacturer recommended is not ideal for that driver that drives short trips mainly in the city. On the other hand the driver that drives mainly highway for an hour every day the 10,000 mile oil change in mostly warm weather above freezing would be good for the engine.

    Small point of disagreement , The MOST important filter on your engine is NOT the oil filter but rather its the air filter . By a ratio of media filtered ,the air filter works harder that ANY of your filters . Not to diminish the importance of the oil change but rather ADD the air filter onto the list of IMPORTANCE on your maint program! rule of thumb: it takes only ONE oz of dust to destroy 100 Cubic inches of engine displacement

    In a previous job I got to visit the lab where a very well known brand of oil was formulated and tested. The chief engineer told me that if I wanted to have virtually zero engine wear I should take the recommended service interval and halve it. So 12k miles becomes 6k and so on. I followed his advice and my last car was 19 years old when it had to be scrapped due to rust. But the engine still ran like a sewing machine.

The executives go to the engineers and ask what is the MINIMUM oil change distance to get the vehicle *past warranty* - not necessarily what is optimal for an extended life of the vehicle. (In fact, it's in their interests for a car to "fail early" - so you go and buy another one, rather than keep it 25 years!!).

    Engine longevity & wear/tear (as well as carbon sludge accumulation) also depends on how the vehicle was driven, whether top tier fuel was used & even whether or not engine uses at least some partial port-injection instead of 100% direct-injection (aka likely carbon sludge magnet). Lots of long, open highway miles, or mostly short trips and/or city-driving stop/go traffic miles can each have a lot of impact on engine health.

    As a 'European' i love watching this content(and the discussion) as over here, annual maintenance - which is basically an oil/filter change plus look over on a 2 post - is the norm. A lot of European cars have variable servicing which push frequencies up to 2 yearly/20,000 miles. Really! Could this be because 80+% cars here are leased and the first owner will be chopping îr in after 3 years, so who cares about longevity? I would say that that tribology is so much more nuanced than given in this video. API standards require oils to meet minimum ASTM test criteria AFTER many hours of simulated usage: Heat - gross/integrated operating temperature, heat cycling - base oil & additive oxidation; wear rate; dirty carrying capability; lubricity (fuel dilution doesn't help here); water exposure Etc etc So depending on the use case, 100 hours or 1000 hours could see your oil dipping below the minimum requirements and hence not protecting your engine. Are you a fleet, where extending intervals by 3000 miles could save you 10s of thousands? Or is it your one car that gets you to work all day and you can dispose of the oil for free?

    First thing: manufacturers recommendation on severe service schedule is my baseline. I typically do a 5k mile OCF using whatever synthetic OEM spec oil I can get on sale, a high quality filter, and the occasional lab analysis. I also do other fluids at 60k for trans, 90k for coolant, and brake fluid every three years. Service on 4wd transfer case and differential is approximately every 30k - 50k depending on the component. I’m not afraid to go longer on the OCF if on a long over the road trip and have done an 8800 mile change with lab analysis showing the oil still held additives and no degrading wear byproducts. Excellent summary sir. Grease is cheaper than steel.

I added half cup of Seafoam or Marvel Mystery to the crankcase the day before oil change and made sure it was warmed up fully. It is my suspicion that the sludge buildup in/on the piston oil wiper rings are what cause these engines to fail prematurely and start burning oil. As it was mostly highway miles, I usually changed oil at 9k-11k intervals. Call me crazy, but 205,000 miles currently and no oil burning issues.

    I'll second the opinion for a "learn to do it yourself" (IF POSSIBLE). I have permanent partial disability (leg) and I can still do it no problem. I have a 2006 Holden VZ. If I'd KNOWN just how easy it is to do when I bought it, I'd have ALWAYS done it myself!! (For the Holden VZ, you don't even need to raise / jack the vehicle (can reach the sump plug with a socket wrench without ever being truly "under" the car), and the oil filter is easily reached from above (under the bonnet)). It took me 10 mins to watch a 10 minute "how to" video on youtube, and about 10 minutes to do the actual oil & filter change. Now obviously this depends on "your vehicle" / design as to how easy it is (or isn't), but if you CAN do it you'll most certainly be better off. Even if you need to buy any tools for this purpose, you'll soon recoup the cost in savings from dealer charges (hint, wait until auto stores have a "discount / sale" on oil or filters, and buy them CHEAP even before you need to do a change). If none of this is possible, I'd still recommend you locate and MARK the oil filter in your car (so you can be sure it's a different one when you pick your car up) - too many dealers have been caught out NOT doing the work they charge the customers for (and the "quick lube" places are even more shady). My car has "issues" at 220,000 km's (potentially facing a complete engine rebuild), I've been told by multiple mechanics if I'd had the oil changed at HALF the manufacturers recommended 15,000 km, none of those issues would have happened (I went 50,000 km's without a change and now it's "sludged"). Oh, and if you do stick with dealer service (I've had bad experiences), INSIST they change the oil FILTER as well - not "just the oil".

    Having spent 42 years in the automotive industry, 32 of those as a shop owner with employees, I agree with your general service interval assessment. Especially for those who don’t read their owners manual. The whole service interval thing has become such a contentious thing. The automotive manufacturers have fallen into the word game, making up and changing definitions. With the 10 and 15,000 mile service interval Almost No one falls into the normal service interval. The normal intervals consist of starting the vehicle in Temperate conditions, driving a short distance to the freeway. Driving at freeway speeds for an extended period and a short distance to your destination. No cold or hot start conditions, no extended, driving on surface streets to get to the freeway. No stop and go traffic, no heavy loads (including passengers) , no short trips, no mountainous, driving, no towing, etc. All that would be under severe conditions, which applies to most of us, that is a much shorter service interval. Also what people don’t understand is that there are other things in their owners manual that are supposed to be done before that 15,000 mile oil change, brake inspections, tire rotations , fluid checks etc. Having a service done at 5,000 miles intervals rather than 15,000 miles intervals can save you money. If you use 15,000 miles as an interval and your tires or brakes only have 6000 miles left, they will sell you tires and brakes before you need them. Not to mention any other issues like belts, leakage, lights etc. A vehicle is an investment you need to protect. On a different note, I love that guy who was arguing with you about oil analysis. At no point did he say he was taking a sample between oil services or what type of driving he does. I love the guys who say “ I do 15,000 miles between oil services, but I do 15,000 miles in two months. Back to the beginning, it’s not the miles but the type of driving. 😊😊

Changing the oil at HALF the manufacturers recommendation (i.e. twice as often) is still much, MUCH cheaper than a rebuild or new engine - and will typically PREVENT the problems that require a rebuild or new engine. Manufacturers extend the service interval as a sales pitch (looks cheaper and less inconvenient to the buyer), and have NO interest in keeping your car healthy past warranty - if it kept running fine for 25 years, you wouldn't buy another one....

    The 2.4L used in CR-V is one of the worst Honda engine and every mechanic knows they will burn oil if the owner will go more 6000 miles/10,000 km on oil changes. While Toyota fixed the oil consumption issues in their 2.4L, by updating pistons and rings, Honda did pretty much nothing. I changed/rebuild dozens of those engines, at least 3-4 every year. In fact there's a one waiting for us this month - it will get low mileage engine sourced from Japan, since it cost the same head/valve job and installing new rings. The same goes for automatic transmissions - they hold less fluid and require more frequent ATF changes. 50k km is the norm. My recommendation max 5k miles OCI on synthetic oil. And if you live in southern US, 5W-30 since it boiling temp is usually higher than 5w-20 oils and doesn't get baked as easy in your oil control rings.

    except that older cars/engines benefit from MORE frequent oil changes than standard/original. Furthermore, increasingly over past 20 yrs of the lengthened OCI's, mounting evidence has risen of engines becoming damaged before they were expected to. E.g. in toyota or honda engines, not lasting anywhere near as long as other same engines do when oil changed more frequently and closer to original classic intervals of 3-4K if car is daily driver. Out of my dozens of high-caliber mechanics, they also say more frequent is better in most cases, partly bcuz various factors of engine systems in past 25 years, as well as reduced quality of engines vs 35 years ago, warrants more frequent OC's if u want the engine to last the often-possible extremely high mileages or high-years that Honda and Toyota can. It's cheap insurance that's for sure.

Also, for severe usage such as extreme cold starts, racing, lots of hard driving, heavy towing, particularly hilly terrain, or maybe even lots of heavy traffic, using something a bit better than the cheapest oil you can find may be worth it for the added protection. Same is true IMO for boosted engines. Changing the oil on time is most important, but if ultimate longevity is the goal, I do think there is a time and a place for premium oils.

Performance was perfect. I never added a drop of oil. EPA estimate was 27-34 MPG when new, but I was still getting 35-37 MPG. Just how much better off would I be if I changed the oil over three times as often?

    You wouldn't be any better off, kudos to you for doing it right. But someone with that same Acura who lives in a very cold climate, makes mostly short trips, drives with a lead food, uses low quality gas and cheap oil & filters, will probably never need to do oil changes because they'll be constantly topping off with fresh oil as their engine burns through it. This is what people don't get and why this debate continues to rage on. How quickly your oil gets contaminated and breaks down is CONDITIONAL. It's not set in stone.

    Same here, but these rules of thumb are not vehicle, driving or environment specific. Certain cars will do fine with 10,000 oil changes if you live in the right area and drive lets say 50 miles to work each way. I have an Acura myself with around 150k miles on it and it still runs like new, and I change the oil every 10k miles with full synthetic oil. But, that car was driven for hundreds of miles at a time on the highway, and it was in a relatively mild climate. If it was used for a lot of local short trips, the oil change interval would be much better at 5k miles...

    After working in engine development the biggest problem is people put the wrong oil in.... It's the acea number that counts NOT 5w 50 or whatever temperature range your country requires. I use the EXACT oil the manufacturer states and it gets changed ever 2 years or 20000 miles... I don't do that many miles in the car only about 5 or 6000 miles a year. But it's always clean, never burns any and hasn't missed a beat in 10 years.

    Excellent, simple video, thanks. I am a retired mechanical, lubrication, and powertrain engineer. Engine owners must understand the engine is one of the dirtiest oil environments of all oils, and it is the contamination amount that defines when to change oil - not how good the oil itself is. Advertising 25,000 mile engine oils to most engine owners, those that plan to keep their cars, is incorrect. Use a good quality API Group III synthetic oil and change oil and filter every 5,000 miles. There, done.

Gulf Coast juniors and The flat head Ford V8 canister filter on the Ford diesel tractor. The Motor Guard on the old Ford f250 390 is almost 60 years old.

    People, most service centers at dealerships don’t know anything about oil. Seriously. There was once a time where paying more, a lot more, to have a dealership service your vehicle was worth every cent as they hired skilled mechanics and did top quality honest work. That’s no longer the case, hasn’t been for a long time. Today you still pay through the nose at a dealership for service but they give zero F’s about the quality of work they do, zero. Change your own dang oil. Some things can’t be avoided, recalls etc. but otherwise do as much work as you can on your own vehicle that way you know it’s done with pride and done well. It’s 2024, you can figure out how to do most things on your own.

    Yes bypass toilet paper filters. Toilet paper is high quality cellulose. They are trying to hide the fact that they are toilet paper filters. Jackmaster puts a high quality roll of Australian toilet paper in a sock and charges 20 bucks for it. I use Great Value 1000 from Walmart in mine. Most use Scott 1000. People assume toilet paper comes apart in oil. It gets stronger in oil. I started with a Frantz in 1963. Went to the top loaders in the 80s. The Jackmaster needs a firm roll. It has no center tube. They depend on the 1 15/16 core seal at the bottom. All I have used is the classic. Not familiar with the Ultra or the bigger models. I sold Frantz Motor Guard and Gulf Coast filters years ago. Motor Guard only makes compressed air filters now. I think Gulf Coast filters only makes paper towel filters now. When I was selling Frantzs Gulf Coast filters had Frantz 3 stackers all over the Gulf of Mexico. At some point the Frantzs went out of production. We also lost the FAA approved AeroFrantz. In 1963 I was working in a full service Standard station. A Standard oil engineer told me to use a Frantz and Delo. Delo came in 20W and 30W. Couldnt use multi grade in a diesel.

    Almost always keep my vehicles for 10+ years. Growing up in West Texas and New Mexico it was super important to keep the oil and filters fresh. The air filter as well and the box vacuumed out. A follow up on radiator care would be welcomed. Engines seem to have come full circle in their operation. It used to be important to warmup a carbureted engine and then it became less so with direct injection. Now with all the turbochargers it’s back to a warmup stage before pulling out.

    Warming up in the driveway has always been bad for engines. It prolongs the time running cold and a rich mixture washes oil off the bore. It’s best to get it warm as fast as possible and that means driving gently as soon as you start it and back out of your driveway. It needs 5 seconds for oil pressure to stabilise and get to all parts - that’s it. Obviously don’t beat on it until the oil (not coolant) temperature is about 50 degrees Celsius

    The only thing I would add is checking oil levels regularly too. All engines "consume" oil, some more than others. By the time one's low oil indicator comes on one could have already caused damage, .. even in not immediately catastrophic. At a minimum, one should check oil level once a week. If one is going on a long trip, check it before and during the trip. After a while you will understand the catachrestic of your car and can adjust accordingly. And, as long as you're at it, one's weekly oil checking routine should include checking tire air pressure too. Otherwise, everything mentioned and the recommendations are spot on. Changing one's oil regularly is the single best thing one can do for engine longevity.

    If OEM milage intervals in your manual are based on OEM oil, and that OEM oil is already a full synthetic, I'd argue it's best not to grant any sort of leeway just because you're getting full synthetic. I typically hit the 6 months point long before I hit the milage anyway, so I'm saying that with no skin in the game 🤣 Many owners manuals also list a "standard usage" and "heavy usage" maintenance schedule. With standard being in the 10-12k miles/1yr, and heavy being half of that. And it's very easy to fall into the heavy usage category. Trying to convince my family they fully meet the criteria for heavy usage has been an uphill battle, even though they want to keep their cars to infinity and beyond.

    David, Excellent video and your time and effort to make it is most appreciated. I need to ask a question. I recently purchased my 11th Honda, in this case, a 2024 Honda CRV Hybrid Touring model. I live in Saskatoon Saskatchewan and get really cold winters and very hot summers. Having purchased the vehicle at the end of October 2023, we had to endure a brutal December. While I park underground in heated parking, I still need to venture outside in those temperatures, park it, and leave it sit for several hours, before restarting to drive it home. The CRV has active grill shutters that assist with getting the engine up to temperature as quickly as possible, in addition to giving me cabin heat, even though the vehicle operates in battery only mode at times. My question is, should I trust the Honda Maintenance minder or go with my gut and change it more often. My concern is that the number of on/off cycles of the hybrid system means that I am more likely to not have the engine up to operating temperature for long enough periods of time to purge the crankcase of unwanted blowby and contaminants. I would really appreciate your thoughts on this question. As others have said, the cheapest engine is really expensive, however the most expensive engine oil is cheap. Thank you.

My second turbo petrol current car is an i30N Performance Luxury Model, I also change my oil n filter every 5,000kms it never blows any smoke or needs extra oil before oil n filter change. So IMO if you want your ICE to last you for how ever long change your oil n filter every 5,000kms, and Air filter every 20,000 max fuel filter 30,000kms, run some injector cleaner at least once a year and you should have an ICE which will last you for a long time.

    While I can't prove this applies generally, I know I personally would pay more for a used car with a maintenance record showing oil and filter were changed every 3-5k, max 6 months. Just my $0.02.

    Love this topic. Love the categories. Assume we can get a car to 500,000 miles. Assume oil changes are $40 per change. Assume you do it yourself. The differential cost to change it every 3,000 miles vs every 5,000 miles is only $2667 over the 500,000 mile life of that engine. If you drive 25,000 miles a year it will take you 20 years to get to 500,000 miles. It will cost you $11 a month more to change oil at 3,000 vs 5,000 mile intervals. I had a 2017 Ford F150 with the Coyote V8 5.0l engine. I changed oil meticulously trying to maintain 3,000 miles. When I sold it I had a spreadsheet of all maintenance I did on that truck. My mean time between oil changes was 3,400 miles. I had 157,000 miles on that truck. It ran as good as new and I am not exaggerating that. It had the old 6-spd trans and after 75,000 miles I started to suck and fill one quart of trans fluid every two oil changes. This turned out to be very easy to do once I set myself up for a quick “takt time” operation. At 157,000 I sold it and received TOP DOLLAR for the truck of $28,000. It was a basic XLT trim by the way. The guy who bought it now has over 200,000 on it. He is also maintaining it the way I did. We stay in touch and we hope to see that motor at least reach 300,000. I find that to be a very reasonable expectation. My old boss had an F250 with the 6.2l. He drove tons of highway miles. He also loves his truck and maintain 3,000 mile oil change intervals. That truck now has 330,000 miles on it. It is his daily driver. His bird dog owns the back seat and is his constant companion in that truck. David. Thanks for a great video. I hate when people tell me that their book recommends 10k mile oil changes. I try to explain why I shoot for 3,000 but they don’t understand the micro physics of sliding parts separated by an oil film. This I’ll never be able to convince them. That’s ok. I just won’t buy a car from them!

    I’m not arguing that changing oil every 3k is a smart practice. Why not every 2k? Wouldn’t that be even better? Why not every 1k? You don’t know that if you changed every 4k that it wouldn’t have still been running as good as new. We live in an economy where some people have to decide whether to spend their money on food or medicine. Luckily I’m not in that category, but if they go every 6k instead of every 3k, that doesn’t make them a bad person, or an uninformed person or even an unwilling person, maybe that’s all they can practically afford to do. Back in the day it was just the standard to go 3k. So was that interval necessary, or did the oil companies want to sell more oil? It reminds me of Proctor and Gamble way back in the day when they had like 90% of the shampoo market but weren’t satisfied. They decided to just change the instructions on the label to say “rinse and repeat”. So now people that followed the instructions used it twice as fast so they could sell more. Was it necessary? The engineer in this video even said, it’s not that the oil loses its ability to lubricate, it’s cause it gets too dirty. So maybe it would be helpful for the car manufacturers to put a color guide in the owners manual, and recommend a certain stage of oil color rather than a set mileage interval. Just a thought.

    "I hate when people tell me that their book recommends 10k mile oil changes." I hate when people like you think they know better than the manufacturer. I've owned my 2004 Audi S4 since it had 13,000 miles. It now has 161,000 miles. I change the oil and filter every 10,000 mi. as recommended by Audi, with Mobil 1 full synthetic without issue. I'm even on the original timing chain guides and tensioners. Now tell my how I'm wrong.

    This all got pretty personal and if I caused any of that I’m apologizing. Oil gets dirty every time the piston hits TDC on combustion. The piston rings are totally awesome by design at how they help control the cylinder pressure but they CANNOT hold it all back. Dirty combustion byproducts come past the piston rings and make the oil get dirty. That “dirt” is carbon byproducts. That carbon is pretty abrasive. That dirty oil may still have lubricity within spec range but it is still dirty. David did say that Toyota race engineers think very short mean time between oil changes is better. I believe this is the reason. Yes it is still “slippery” but it’s also now dirty with carbon blow by and that means it is also now a bit more abrasive. I shoot a lot. I’ve studied carbon deposits in F-Class Benchrest rifles. Carbon deposits left uncleaned are incredibly tough to remove. Especially the “carbon ring” just forward of the bullet right before the lands. Carbon can build up there enough to not only open up shot groups but also produce excessive (dangerous) pressures. I’m wondering is someone out there can technically describe what an oil filter is capable of filtering out of oil? Does an oil filter reduce carbon in the oil from blow by? Or is it only good for larger particles? It would be awesome to understand pressure gradients across an oil filter at 2k, 3k, 4K, 5k up to 10k or even 15k. I would think that when oil pressure gradient picks up to a certain point that’s the time to change oil. I suppose that kind of pressure gauge could be installed. I just changed my F-350 7.3l gas engine oil today. I have 58,000 miles on that truck and my mean time between oil changes is 4,600 miles at this point. I am going to stick to that. Personal choice.

    When you buy a new car, it normally has about 5 years free servicing anyway. If second hand, check for service history. If none, hope for the best and use synthetic oil and change oil and filter regularly. Don't forget to check air filter too. That's overlooked a lot. 😬

    I agree it would be better to buy new, instead of lease. But I have been buying off lease CPO Toyota and Lexus because of the lower cost and service history. Although only the manufacture's oil change interval was followed (A) early in it's life, I change oil with (B). Both of these vehicles. 2014 Camry (150K miles), 2008 Lexus ES350 (125K miles) consume very little oil and run great.

    I would add a caveat that buying a leased vehicle or or a "program vehicle"/ demo or a used vehicle that is no older than three years can be fine, provided that the Carfax indicated proper oil changes and maintenance. In my life, I have never been stuck with a vehicle that was not cared for properly. Additionally, buying new does NOT guarantee success. As an example, I have experienced a Coyote engine that needed a quart about every 1,500 miles; according to the manufacturer, that usage is normal. I had a second Coyote in a different truck that never used oil during an entire oil change interval. I also had a 305 cu. in. that, after the 12k warranty was up, showed 2 adjacent cylinders with wet spark plugs.

    I can’t remember the last time I saw a vehicle replaced because the engine was worn out. Almost always it’s the car that falls apart around the engine. The transmission fails, all the accessories start failing or the body rusts out, or the cost of repair exceeds the value of the car. Seldomly do I see and engine needing replacement.

    That's the trouble when you buy a used car.You don't know how often the previous owner changed the oil & filter unless you know the previous owner personally. If you're buying a used car check the oil level dip stick & if you see sludge on the stick, don't buy that car! That engine is on borrowed time & ready to blow!!

    Took me about 20 years to put 250.000 miles on a 84 Subaru. Never drained the Mobil 1. Changed the toilet paper filter once a year or about every 12.000 miles and added a quart of new oil. A Caterpillar lab said the oil looks good for that many miles but suggested a filter change and a new quart of Mobil 1 every 6.000 miles. They found some caramelization. I removed the full flow fillter when the car was new. The engine was still running good but both head gaskets were leaking oil when I gave it away at a little less than 300.000 miles.

    127,000 miles. Toyota Avalon is 20 years old. Change every 3,000 miles or once a year, whichever comes first. The family had 3 other units, same model and they each went over 250,000 miles. Change the radiator fluid and drain transmission sooner than Toytoa recommends.
