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.

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.

[@JR-zw2vb]

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.

[@DeusKDuo]

@@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.

[@lobsterbisque7567]

​@@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.

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.

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).

[@LibertyWlk]

All persons talks of mileage but what about time?

[@FlyingFun.]

@@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.

[@reallifeengineer7214]

​@@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...

[@FlyingFun.]

@@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🤙🏻

[@almizzyracing8004]

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.

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.

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.

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.

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.

[@curt248]

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.

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.

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.

[@DzastinasLTL]

Well, this is a big discussion topic, but keep in mind transmissions are not internal combustion engines (ICE) and the oil inside the transmission does not "work" anywhere near as hard as ICE oil under daily-driven conditions. Also, changing ATF of a high--mileage auto trans can actually lead to undrivable car due to the clutches being worn out to a point where the old ATF has more clutch material in it to keep sufficient "grip" than the clutches themselves and so by changing/flushing ATF you are now removing this clutch material suspended in the old ATF also, thus rendering the transmission to slip.

[@apexseal2811]

Austin That is completely BS. No oil lasts forever (unless manufacturers consider "lifetime" as 100,000mi, and then you must replace your transmission). My father had a C280/C300 2008 (W204) Mercedes-Benz with the 7G-Tronic transmission. When these were first introduced, MB said ATF lasted forever, hence they didn't include any drain plug nor oil dipstick. Later on they begin to notice some transmission wear due to lack of lubrication (oil breaking down), and SUGGESTED the ATF to be replaced every 60,000mi or 5 years if I'm not mistaken. When we took the car to an independent MB shop (the vehicle was dealer services for its entire 10 years of life until then) for a regular service + ATF and filter replacement, the mechanic said that when he removed the oil pan it already smelled funky, and there was no guarantee the transmission would function properly (because, with old oil, the pump works at a lower pressure due to clogging and possibly causing shifting delays although ATF was changed). Transmission flush is NOT recommended in these cases, as the previous comment stated. Car appeared to run perfectly fine then, but was finally sold some while ago.

[@tscook10]

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.

Understanding this video has inspired my question which is: Why don't car engine makers include a ''pre-lubing"/"lube-priming" kind of process where a person turns the ignition key from position-zero through to position-two (battery online) and is prompted by a "lube-protection-system" to "please wait, pre-lubing or lube-priming" in progress, and depending on car make, the person would see a graphic progress bar or clock countdown insicating when it's ok to turn the key to position-three to crank the engine to a start? This process would use electric power from the battery of the car (it may be as much power as used by the starter motor to crank the enginento a start) to power an electric oil pump to pre-spray/pre-circulate just eniugh oil around the engine to coat those sensitive moving parts that are exposed to dryness that welcomes wear during start-ups...before the starter motor is cleared to crank the engine to a start. This idea of mine is inspired by the pre-heating glow wire in diesel engines which must be allowed to get hot enough to warm the air entering the ready-to-fire cylinder...like we all know, this is a must-do process on cars with diesel engines and I thought it would be great for petrol/gasoline engines to have the pre-lubing/pre-oiling/pre-spraying feature. I'm aware that something like this would unfortunately increase complexity, parts-counts, weight and costs to the car featuring the system, but I'm tempted to think that in the long run, start-up wear could be reduced super-significantly.

In fact, many newer cars (made in the last 10 years) supposedly claim you can go 10,000 miles between changes, although I personally still stick with every 5,000 miles or 6 months, whichever occurs first. But it's not the end of the world if you go over by about 2-3k in most cases. The only time it might is if your engine is worn and leaking/burning a lot of oil and it runs low or gets excessively dirty.

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.

I once worked in a materials lab with a clued up motorcycle racer. He did routine oil tests on his Suzuki. After two year of close monitoring he optimised his oil changes to 3000km less than the recommended 10k changes, and replaced his plugs every 5000km. The oil got contaminated by zinc and magnesium beyond 7300km intervals, going exponential at 9500km. Oil brand didn’t make much difference, but synthetic oils showed wet plate clutch contamination (I.e. wear) within 1000km. I had the same model bike: after thrashing it for a decade, using his maintenance schedule. The motor at 570k km still ran sweet, smooth from idle to its rev limit at 13600 rpm with zero rebuilds. Then the bike was stolen and stripped for parts. Five years later I found my engine in another bike still running sweet. Most bikes engines are junk at 300k, so I was very happy with my colleagues advice. But, in off years when injury prevented riding I never bothered changing the oil, I just kept to the 7000km interval. Not bad really for a wet clutch plate bike frequently ridden at its limits averaging 10500 rpm, with frequent clutch less gear changes, and occasionally turfed on its side onto the tarmac with the unloaded engine screaming. Get your oil and plug change intervals optimised and kiss goodbye to engine repairs. Note manufacturer intervals are a compromise between worst case use, and the manufacturers desire to sell you a new engine.

Because we now have so many people driving vehicles but never reading owner manuals or understanding the importance of maintenance, many/most manufacturers have oil change reminders built in to their electronics. The vehicle will tell you by way of a tone and message on your instrument panel display every time you start the vehicle. The actual mileage when the reminder activates varies based on factors such as the type of driving done as well as the miles. Drive a lot of highway miles, you can go longer between changes. Do mostly stop and go driving, your reminder will activate at a lower number of miles. This is all tracked by the powertrain control module (PCM) as well as other computers in the vehicle. So if the average recommended oil change interval is 7500 miles for instance, your reminder could activate at 5000 miles, 7500 miles, 10000 miles, or even higher. Or you could do like me and just change the oil every 5000 miles. As an old retired automotive engineer, I have a lot of first hand experience with this subject. My opinion is use a top quality synthetic oil and don't try to stretch the miles between changes. Your engine will thank you and reward you with many extra miles before it bites the dust.

I just went on a vacation and rent a car the fully synthetic 0w20 have became like 90w140 oil and it's so black the last services was 11000km and now it's 41000km supposed to change every 10000km and I ain't complaining as it isn't my car. Thanks for the information Jason. Love your videos.

[@ClemOnShow]

Thank you for the details. It would have been nice to also cover : 1 the influence of short trips vs long trip on oil wear . 2 an example of lab results for both scenarios. 3 the chemical differences BTW mineral and synthetic. Thanks for the thorough videos !

[@nyplantingsgardendesigners5645]

You can find these in field studies from various companies. Motor oil studies have been performed for decades.

[@Ddog72]

an example of lab results for both scenarios... Theres a few videos on this. On a microscopic level, its not as doom and gloom as the video claims, the oils tested were fine upto 15,000 miles. Only then were trace metals found.

[@TheWilferch]

Pointed question--> multi-viscosity oils are all we use now....and Viscosity Improvers (VI's) are used in the mix to get us there. Also....oil (itself) does not "wear-out"....only the VI's do. So.....it was therefore recommended that multi-viscosity oils with low weight ratios.. ( say....10W-30...a 3:1 weight ratio from the *base* stock 10 weight ....to 30)...use LESS Viscosity improvers than the later 5W-30 oils (6:1 ratio). So the argument goes....the 10W-30 is more forgiving of late oil changes (say every 5000 miles).....than the 5W-30, because it has less VI content to wear out, with less chance that you are ending up with only the core 10 weight oil that it started out with, before the VI's were added that get you to 30 weight. Comments from anyone deep into this topic ?........

[@Taydrum]

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

[@regierse]

I went over the recommended limit by ~500 km on my last 2 oil changes and I was fully expecting Jason to say that my car is basically broken now lol.

[@ChiDraconis]

Far from it you can go quite a ways beyond recommended ~ just do not let it get low → this is an ideal product; I use it with above excellent result;

[@ralphwood8818]

I stipped draining il in 1963 using oil filters that clean oil and adding new makeup oil at filter changes. I use the Jackmaster Classic the Motor Guard and the Gulf Coast filters. I am using Super Tech 20.000 mile oil. Never cared much what the oil changers recommend.

[@rshettle123]

The single most important factor with any oil is its film strength, that which protects against metal to metal contact or shear, anti wear additived. Synthetic base stocks alone only give you a higher resistance to temperature breakdown, which of course is good in itself.

[@anangelshero0410]

I found this video really "judge-y", and all I came for was the "what to do" part. Get my oil analyzed...got it. In the Army we'd send samples out on a schedule and only change the oil when the lab told us to. Reality is the intervals depend on a lot of things that may or may not exist. If you missed one oil change it's not the end of the world.

[@kris.monroe]

A good friend of mine, for years, didn't changer her oil - just added more, keeping it topped off but did occasionally change the filter.. Blew my mind and now I offer to change their oil regularly. XD

[@kstricl]

I have an old truck with a tired chevy 350. The oil self renews like that every 3-5k miles. I can literally just change the filter every 6 months. 😂

[@LachskoenigIV]

What if I told you I did the same on my first car for 4 years and ~60 000km?

"ICE engines" is like saying "VIN number"

[@hugostiglitz8378]

Paul D or ATM machines.

[@MotoCat91]

While true, I often give it a pass when the acronym + redundancy is still less syllables and easy to understand eg: ICE engine is faster than saying internal combustion engine, VIN number is faster than Vehicle Identification Number etc And many people won't immediately know that ICE is referring to an engine type unless they've been watching for a while or are very familiar with the language so saying engine afterward helps with that.

[@cccEngineer]

I say VI-Number lol.

[@MaurizioOiziruam]

or LCD display

[@austinshoupe3003]

Technically correct. However, the redundancy flows better with the redundancy in many cases.

[@Nocturnalzyx]

I saw an oil analysis that claimed a guy’s “spirited driving” BNW had really impressive results at a 7500 mile interval (after an initial 10,000 mile interval) and even encouraged him to experiment with another 10,000 mile interval.

[@TheYehat]

No matter of the many comments simply ignorant, but engine oil is complex matter and VERY important - not only the interval, but the actual oil. And no - not all are equal. Will be very helpful if we see a dedicated lecture on that topic. Thanks.

I generally tend to aim for 4000 mile oil changes, because my car is a 30 year old machine with nearly 200k miles on the odometer and i want to make life as easy as possible for my little engine.

[@ThePolerbearproducts]

My sister's 16 Chrysler Town and Country once went 10,000 Miles on Conventional Oil before I changed it. Wasn't as horrible as I thought it was gonna be, There was a lot of blowby as it reeked of Gas and it was brown but there weren't any head gasket leak symptoms. It's up for changing in a few weeks I'm definitely gonna send a sample to Blackstone labs to make sure nothing bad happened.

[@johannkuhn5685]

Intersting video. But why didn't you mention oil age? Not all cars see a lot of use, and it's commonly known/believed that oil must be changed at least once a year (contaminants breaking it down?).

[@ianwilliams487]

Yep..very true,,Stopped working ,the old ute just trips to the shop,,never really got to operating temp..Lucky to do 5000 ks in 2 year,,left oil too long and now i have a tappet rattle, Even though i had been very good with service,,the fuel by-pass the pistons, when cold did the damage,,Never got to a temp where this fuel would re-burn through PCV, Hence one noisy V8 on start up,,Does go away but damage is done,,and a costly repair,,VY ute 5.7 , 6 speed ,LSD,, less than 170k ks on it,,

[@tacbear]

I have a 2000 Mustang GT with 25K $$$ in modifications that goes about 2000 miles a year. I change the oil every 5000 miles (Mobil 1). This means the oil gets changed every 2.5 years...IT RUNS LIKE A TOP!!!!

Depends how old the oil is. If it isn't badly used, it can sit for THREE years and still have good results from a Blackstone Labs oil analysis.

[@FerralVideo]

I was curious about this myself. '06 Prius, maybe 5k a year. My commute is only 2 miles, and I know that this is bad for an engine, so I usually commute by bicycle. Usually also visit my folks once a week, so a nice 20 minute trip across town to get everything warmed up.

[@redguard153]

I got some pretty strange looks when I brought my Tesla into the shop for an oil change and all they could find under the hood was the wiper fluid fill port.

[@Bob_Lob_Law]

I feel like they would get pissed for you wasting their time, but it also sounds quite hilarious. They should EVs dont have oil.

Hope they changed those electric wire fluids. If you forget to do that in time, it'll cause all kinds of problems with electricity starting to flow too slow and getting too hot, so you'll risk exploding your blinkers!... which need their fluids changed regularly as well!

[@beetleything1864]

coulda changed your rubber wind up band that makes it go.......

[@txmoney]

Change the oil/filter early! If your vehicle has an oil change interval indicator, change it long before the maintenance reminder turns on. And you should change the oil/filter even sooner the older the vehicle gets. My 2018 Civic EX-T has an indicator that tracks the viscosity. The oil indicator adjusts the change interval based on usage (short trips and city driving requires sooner oil changes) rather than just mileage. But generally, it requires an oil/filter change every 5,500 miles using synthetic 0W-20. I change it when the indicator hits 30% or earlier (roughly, every 4,200 miles). I plan on keeping my Civic for well over 250,000 miles.

[@Otto45]

This triggers my OCD being a motorcycle junkie! I usually always change my engine oil after every 950 KM & never really had any issues with sludge or carbon deposits. Its kinda overkill but, better earlier then later LOL
