NEW Engine BREAK-IN: Truth or MYTH?

Back in the day, new engines required a break-in period. With today's modern manufacturing techniques and material technology, do modern vehicles still require a break-in period? In this video, we utilizes the analytical power of used oil analysis to determine the truth.
In a previous video, I changed the oil in my daughter's new Toyota Corolla before it had 1,000 miles on it. Here's the link to that video: • AVOID the ONE MISTAKE ... , but many viewers commented and questioned if that was necessary on a modern vehicle. Since this channel relies on science instead of speculation, I took a second oil sample at at 3,000 miles to compare the wear trend. If the wear rate changes, then the engine is still breaking in, but if the wear rate doesn't change, then the engine was already broken-in. The oil analysis results will reveal the answer. Do modern engines still require break-in? Let find out!

Thanks for all the comments, suggestions and questions. I appreciate them (even though the volume is quite overwhelming). Just a few points to clarify… I didn’t say these new engines are not run at the factory. I know they are started and checked for leaks, etc…, but that is not breaking in the engine. Also, this car was built in Japan. I am not speculating that because it is a Toyota. I know it was built in Japan because all of the paperwork with the car said it was built in Japan. Also, the 0W-8 is an indication it was built in Japan because that is what Toyota recommends in Japan. Here in the US, 0W-8 was still not available when she got the car. I hope that clears up any confusion.

I would still avoid using any 0w8 oil, there is literally zero tolerance to shearing and fuel dilution.

A HUGE debate online is the weight war. One debate in the VB WRX community is the 0w20 vs 5w30 crew. Subaru was recommending 0w20 when the 2022 WRX was released but now Im hearing they are switching back to 5w30. As you probably know Ford switched back to 5w30 from 0w20 a couple years ago. I do all my own oil changes and I changed mine out (2022 WRX) at 1k miles with 5w30.

[@xynostasos9022]

@@chrischarles9218 for Mustang Coyote 5.0L V8, Ford specifies from 5w20 all the way to 5w50 for "track" use. So it's easy to get the point. IIRC, there is a video here that describes the relation of engine oil operating temperature and viscosity. Modern cars lacking oil temp gauge (apart maybe from a few VW/Audi TSI cars) makes this whole thing even more frustrating.

[@chrischarles9218]

@@xynostasos9022 I was actually referring to their Eco Boost engines as Ford found out 0w20 was a little light for a turbo vehicle. Oh Im happy to say my 2022 wrx does come with an oil temp gauge.

[@sunking2001]

I bought a new 2005 Camry 2.4. The dealer had some gimmick of "the first one is on us" oil change at 3500 miles. I asked about the 500 - 700 mile "break-in" oil change. They told me that was "old fashioned technology." I changed the oil myself at 700 miles and when I held my trouble light over the 700 mile oil in the drain pan...there were millions of tiny metal particles floating in the oil. I felt good about getting rid of all that metal at an early life of the engine. I owned the car for 15 years and racked up 218,000 miles before I sold it. The engine ran like it was "brand new" for all those miles. Fast forward to 2020...I bought a new Camry 2.5. I did the same thing but, this time I didn't see millions of metal particles in the oil. Still...I felt good about that first oil change. I totally agree with the first early oil change. BTW...while purchasing my new 2020 Camry the financing clown told me they break in the engines at the factory. I knew it was total bullshit because...how can they have the time and resources to break in millions of engines at the engine factory? Many of these dealership clowns will lie to anyone about anything...even their own mother!

[@jublywubly]

It would be impractically impossible to break in all those engines. They'd need to actually drive the cars for the break-in period. Even if they were able to run the engines for all those hours, it's not the same as the engines being under load.

[@pfcstuck]

I just got a new Ford Maverick (Fx4 and tow package). The dealership did not tell me about break-in. When reading the owners manual I found that a 1,000 mile break-in period with a mix of highway and in-town driving is recommended before off-roading, towing, or "aggressive driving".

Have always believed in break in. Brother bought a brand new Jeep Wrangler in 1993. Drove it home 100 miles and changed the oil. Changed it again at about 1000 miles or so, and then normal after that. Engine lasted forever. Also changed the diff and trans (manual) fluids at 1000 miles with quality synthetic. Really liked that Jeep, and ran surprisingly well for a 4.0, 5 speed and 3.55 limited slip.

[@themotoroilgeek]

[@cj7fun579]

I totally agree! New cars today are not broke in. When I bought a new 2013 Chevy Silverado 5.3, It sayed in the manual not to tow, let the engine idol or drive at steady speeds to much of a length of time, and to gradually accelerate for the first 500 miles, I know it's hard to believe but that's exactly what I did just to see if this was for real, and if it really made difference, and I gotta say, it seemed to have really worked. I've change the engine oil around every 6500 miles using Mobil 1 5w30 and AC Delco filters. So far, I've only had to add less than a half a quart of oil between oil changes and it now has over 214,000 miles now. This Engine has the AFM with Cylinder deactvation also. Early on when I had less than 50,000 miles on the truck, i had discovered that some of these engines had lifter problems, So I decided to get a Power programmer and disable the cylinder deactivation so that it stays in V8 mode and have never had a problem since, and get same MPG,s as before, plus at the same time I added an oil catch can. I think this has made a huge impact on the longevity, and you woulded believe how much contaminated crank case condensation and sludge I have stopped from going into the combustion chambers, and coaking up the intake valves, this Idea about the catch can, I had read about where the Corvettes and Camaros were having problems on the race track at around 20,000 miles on the engines with direct injection and had to have the intake pulled and manually clean the intake ports because there is not gas flowing into the ports to help keep the oil washed down and from sticking to the valve seats and stems causing performace problems. I know this turned into a long winded reply, but I figure it may help since it's oil related and can effect the moving parts of the engine. I really enjoy your videos 👍

The Chevy manuals still recommend you break the car in slowly.I purchased a Malibu Premier last year and did as they recommended.The service rep did think I was a little nuts for getting an oil and filter change at 700 miles though.What is $90 with the cost of engines and transmissions these days.Been doing this since 1973 when I bought my first new car.Never an engine or trans failure.

[@natelorimer8567]

I'm one that's for the changing the oil often sooner when new. But I always run semi hard. That seats the rings. They have to wear in. The bearings I don't worry. If there is wear, then the tolerance was not set for the oil to have a film between the parts.

[@jeffamburgey7485]

This is a pretty confusing issue to me. I hope my version of clarification is correct. In my new LX 600, I did the first oil change at 500 miles and at 5k since then. The dealership thought I'd lost my mind, but I feel better now, although I didn't send it off for analysis.

A little story from an expat living in Spain: I've been here for about 28 years. Back in 2017 I bought a Volvo XC90 AWD D5, which is a four cylinder twin turbo diesel engine (not available in the states AFAIK). I was stunned to see that the manufacturer (and dealer) oil change interval was 15,000km (about 9,300 mi), even the FIRST one! I remember arguing with the gm of the dealership and later, with one of his mechanics that this cannot be true as all engines need a break in period and that IMHO the first oil change should be around 3000km (about 1,800mi) and NOT the freakin 15,000 as stated. I was told that those days are over, and that modern new engines do not require a break-in period as they did back in my days (I grew up messing around with engines in the 70's). I told them that was bs and that I would just have an independent shop change out my oil at 2000 or 3000km to be safe. The dealerhip's retort? If I do that I will void the warranty that came with the vehicle. Geezusfuckingchrist. So stupid me listened to them and have been faithfully completing oil changes every 15.000km (and occasionally changing out the oil about every 10,000km with an independent shop since my warranty period has expired). My Volvo is still running fine today but over the last year or so I've noticed it has begun to consume a little bit of oil between changes. I now have 200,000km (about 124,000mi to my metric challenged brethren :-), almost all of which are highway miles. The bottom line for me personally is that I wish I had just listened to my own common sense and insisted on an oil change interval that I KNEW was the correct one. BTW, this same dealership insisted that my transmission fluid was for the "life of the vehicle" and have refused my requests to change it out. So my fluid now has 200,000km on it, and I'm told by an independent mechanic to leave it alone as changing it out now this late in the game may induce problems to it. I'm so stupid for not listening to myself and not changing it out at least twice now. Sorry for the long post. Love this channel, btw. Thank you!

[@acdii]

Theres no truth that changing the oil early would have prevented any oil burning today. Do you even know where the oil is coming from? Could be a valve guide seal and not the rings. I have a 2007 RV4 with 190K miles on it, nothing special was ever done, just drove it like normal and changed the oil at the recommended intervals, doesn't burn a drop of oil and still runs great, chirping tires.

[@themotoroilgeek]

Thanks for watching and sharing!

[@jpdw7543]

I agree with appalling68, I don't listen to the dealer anymore when buying a new car and do my first oil change myself without informing the dealer, with OM parts purchased by another dealer. Standard oil interval is now 25.000km by the dealer and I do it myself in the middle. I hear the same from automatic gearboxes, once the oil is too long inside like over 150Kkm, they advice it's better just fill up and never change it anymore.

Great information with actual scientific analysis. Next question though is what about lifetime fluids? I have had Toyotas and others and never changed the transmission fluid as they say it is a lifetime fluid and had no issues until the 180k mark when I got rid of it, but am still curious on the matter. Older mechanics will say change it regardless, newer mechanics say never touch it depending who you talk to. Also waterless coolant or lifetime coolant that Toyotas uses etc. Curious on the analysis of this.

[@grungysquash1]

It all depends on what you consider a lifetime to mean. For manufacturers, lifetime is simply the warranty period.

[@robertct06]

That crazy guy Scotty says lifetime of those oils is the warranty period. He claimed that he argued with someone from some company and said he was gonna test the oil and they back tracked and said they’d change it

[@bertblue9683]

The car care nut explains the ATF very well. He wants you to change it every 60k I believe. Unless it's never been changed. Then don't touch it say, around 100k. He says he's seen more damage or trouble after a change. Weird I know. But check him out here on the YT

[@themotoroilgeek]

We are going to change the transmission fluid at 10k as well.

[@bigdog4574]

Mazda cx5 per manufacturer life time fluid is 90k miles!

[@michaelblacktree]

That was pretty conclusive. BTW, here's another good quote, from Grace Hopper: _"One accurate measurement is worth a thousand expert opinions."_ 😎

[@themotoroilgeek]

Good point!

[@Mark-rw3kw]

The only problem with the oil analysis measurement presented in this video is that there appears to be logic problem here. Even if an engine oil has been broken in at the factory, doesn't mean that oil has ever been changed, and any wear metals from factory break-in are likely to still be in the engine oil. So the conclusion about whether or not the engine is broken in a the factory can't be determined by the first oil change at 1000 miles, unless the first oil change is immediately after taking possession of the car, and then the second oil change is sometime later (like maybe 1000 miles), and then the third oil change is about 5,000 miles or so. If the third oil change at 5000 miles (representing 1000-5000 miles on the OD) has significantly less wear metals than the first oil change (taken immediately after possession of the car with about 5 miles on the OD), then it seems reasonable to conclude that some engine break-in occurred at the factory, which showed up in the first oil change taken with 5 or less miles on the OD.

[@JJRossi]

Awesome video, i love that your information is based on scientific analysis. Cold hard facts are beautiful. What im wondering is if the difference in ppm before and after is actually enough to harm an engine. Fyi.. Im absolutely not an expert or a mechanic. Just a curious idiot. U would think that the small difference in "Part per Million" would be negligible. That being said... i certainly would want the lower of the numbers inside my brand new engine lol.

[@bobbygetsbanned6049]

It's abrasive either way so less is always better.

[@themotoroilgeek]

Thanks for the question. In my experience, a higher level of wear leads to an increase in the wear rate, so 40 ppm of copper, if not dealt with, will lead to an even higher level of copper. Unchecked, it could lead to severe damage and/or possible engine failure. The science of used oil analysis was pioneered by the US Navy and Air Force to reduce the number of aircraft failures by catching problems well before they become significant.

[@NeasYellek]

If the thing is sealed and water-tight, then all the salt in the world won't matter.

I grew up working with my stepdad who had a machine shop and was a very good engine builder. He was always very strict about engine break in. When I started rebuilding engines for my own vehicles, I did the first oil change at 100 miles, the next one 500 miles, then another at 1,000 miles. Then every 3,000 after that.

I think modern engines are a different animal altogether. Especially a Toyota or other highly engineered engines.

[@alfredomarquez9777]

​@@Alex-gx5mb Not exactly: Those very "modern" engines have much closer tolerances... so those require thinner viscosity oils, especially for their VVT or variable valve timing mechanisms. BUT, their cylinder walls are machined exactly like previous engines, and undergo the same cylinder wall and piston ring mating (Break-in) process, and require the same metal particle elimination at initial oil changes scheme.

[@peterdarr383]

Yes - 100 miles and throw away the cam lube, larger metal shavings and any machining residues from your "clean" rebuild. Put magnets on your oil filter to collect more iron.

[@eduardonicolas1638]

Very good channel, and very good videos... many thanks for them... Current engines have a quality of machining that no longer requires the long break-in periods that older engines did, but even so, the break-in period exists... we can verify it by seeing how the engine noticeably lowers its fuel consumption after of 5 or 10 thousand km... Some engine rectification workshops advise, in an initial period of about 2000 km, to use the engine without demanding it but at varied regimes... I, on the other hand, am in favor of using it at low and moderate regimes in the first thousands of km...

[@rosewood1]

As someone who has built engines both professionally and privately I know that a new engine will generally be made with tight tolerances in many areas. An engine is made of 100s of parts and these parts will suddenly be expected to move on bearing surfaces at varying temperatures at speed. I always run a brand new engine very gently statically to start. Then check tolerances and change the oil. And I will get particles. I then drive gently at operating temperature retorque and change the oil again. And then check carefully during service. Result is perfect compression and combustion. But I do know many manufacturers are not this fussy. Oil is cheap

[@apexriders_]

I took you advice. Went and changed my oil today at 700 miles. I just bought my 2024 tundra 2 weeks ago. The dealership looked at me like I'm crazy when I asked for an oil change. I also asked for an oil sample. Explaining to them its a new engine. It's breaking in. There will be micro metal particulate in the oil. Long story short. After they changed the oil and inspected the sample of the first 600 miles oil. They found that I was right and gave me a huge discount on that oil change. Anyways I'm glad I changed the oil. Cause regardless of what any manufacturer says I think a new engine needs that 600 miles oil change.

[@themotoroilgeek]

Right on! Thank you for sharing your experience.

[@jamesbosworth4191]

When I rebuild an engine, I let it run at a fast idle for an hour with SAE 10W, drain that and drive the car at fairly low speeds for 500 miles with SAE 10W or 20W depending on time of year, drive at moderate varying speeds, drain that at 1,000 miles, fill with SAE 20@ and drive at moderate varying speeds for the next 1,000 miles, then go to my usually 2,000 mile oil changes. In summer, SAE 30, in winter here in Northern Cal where it doesn't get very cold, SAE 20W. I change the filter at each of these changes. Many say overkill, but I have never had a lubrication-related failure and routinely got well over 100,000 miles on what would now be considered very poor quality oil, so I must have done something right.

[@creiganderson]

1. How much does the testing & analysis of engine oil COST the typical car owner, in addition to all the oil changes being done? 2. When you substitute a lighter weight oil than the ones recommended by the factory, aren’t you doing things that could invalidate your factory warranty?

Believe it or not, most OEM filters are pretty good as they are designed to be fairly restrictive and conservative. Same with air filters. If you want the cleanest engine, you want slightly less airflow and finer filter material. The wear you see in engines run in the desert with those K&N type filters is sometimes quite shocking. I'd rather sacrifice 5hp and have half the junk in my engine and oil (where all the grime and dusts ends up anyways). EDIT - K&N filters were designed originally for people who raced and cared about winning more than engine life as most rebuilt their engines after a few races anyways back in the day ( and often still do ). I really don't recommend them for people who want to keep their cars for decades.

I just bought a new 2024 Mazda 3 and this video was really informative, I''ll be sure to do the first oil change at around 600 miles. From watching your videos I feel like I have enough knowledge to make sure my new car lasts at least 10 years. Also, if you think about it, it makes sense that the engine of a production car wouldn't be broken in at the factory. Sure they fire it up to check it for leaks/issues, but it doesn't really make fiscal sense for a manufacturer that makes hundreds of thousands (if not millions) of engines per year to run each one for 5-10 hours to break it in. I could maybe see a sports car or luxury car engine going through a factory break in, but I really doubt the average production car is.

I have a Briggs and Stratton lawnmower engine where I deliberately have never changed the oil...for 30 years so far. I just tip more in when needed, and it's still going just fine😂 I don't do the same with my car, but on modern synthetics 10k miles is fine between changes. I've never had an engine failure in over 50 years either. Modern engines are built to far closer tolerances, so running in is less crucial, but I think it's still important to go steady on an engine in its early days. Changing the filter is as important as anything.

[@matsudakodo]

​​@@timhancock6626 the key thing you're missing is direct injection which causes more fuel to get into the oil (fuel dilution is the term). This lowers the viscosity of your oil and leads to it needing to be changed sooner. Turbocharging a direct injected motor further increases the need by cooking your oil at higher temperatures. On these motors, change at 5K miles or 12 months, whichever comes first.

I’m not sure about other manufacturers but GM states in the owners manual that the engine needs to go through a break in period and recommends not to drive at single speed for long periods (cruise control) etc. although, they don’t recommend an altered only oil change interval. As the owner of your vehicle I think it’s really up to you to do your own research and be informed on your vehicle. If you’re not sure I would error on the side of caution and change the oil sooner rather than later

I didn't send oil in for an analysis, but I'm sure if I had, the results would have been very similar to the oil in your daughter's car. I subscribed to your channel after watching your first video of this vehicle and will continue watching. I'd be interested in your ideas of running higher viscosity oil in these new engines.

First, GREAT CHANNEL! Very nice to see someone doing it the right way... I'm a big advocate of engine break-in and an early oil change. I've done it on all new vehicles and new replacement engines I've ever owned. Your video prompted a couple of questions. Frankly, I've never heard of nor considered if other motor vehicle systems would benefit from a "break-in", e.g.: transmission (auto/manual), transfer case, and differentials. What do you think? Just as background, I'm not a certified tribologist, but studied lubrication as an undergraduate in mechanical engineering (and in graduate school for other reasons beyond typical lubricants and lubrication applications) and applied that knowledge many times over a 40+ year career in lots of interesting circumstances beyond lubricating machines :). My go to general text/reference book is "Engineering Tribology" by Stachowiak/Batchelor and always Mark's Standard Handbook and the Machinery's Handbook, as well as other text/reference books more specific to my applications.

[@larrycollie5330]

I have always changed the first oil change way early for exactly that reason break in, I remember when they told you to very your speed and not drive over 55 mph for the first 500 miles to break it in better , now they say you don't need to,you just proved that wrong, change early and don't go 10,000 miles between changes.

Lake, you said toward the end that you showed that changing oil early reduces wear. That is certainly intuitive, but could you elaborate on the science that shows that? Where have you done a comparison of engines with and without early oil change intervals? It seems intuitive that getting rid of oil with a lot of little particles in it would be beneficial to the engine over the long term, and I always do an early oil change myself on new engines, but I’m not sure you’ve actually shown long term benefit anywhere. If so, please provide a link. Thanks!

[@Sheepleton]

Many cars come from the factory with full synthetic oil and trans fluid now. Toyota runs 0W-20 in half their stuff and they don't make anything but synthetic 0W-20.

[@WR40036]

Trend is definitely toward full synthetics. Exxon is working on a synthetic gasoline in South America, which should reduce wear. They will use it first in racing. The process involves using water, carbon dioxide and generally wind generated electricity. More details on Exxon website. Not being done in US (at least no plans at this time). Believe initial site is somewhere near Venezuela. Toyota is also working with Exxon on this program. Should make engines last longer (maybe less friction from sulfur and other elements). Much cleaner than the German process used in the 1940s (which used coal). Heard several South American countries use very high levels of ethanol instead of gasoline, even some of the countries that export large amounts of gasoline. I've been using 0w20 full synthetic for about 7.5 years, with a 2k-5k change interval (about 6 months, usually time expires for me before miles). Unsure what prior owner of 3.5 years did. No significant oil use between changes (level ok for full 6 months). People have had trouble with some engines if they use heavier oil (does not always lubricate top of the engine fast enough to prevent wear around the camshaft and valves, I've heard). Brake and transaxle fluid will be changed in 2024 (around 64k miles). Transaxle is "lifetime" according to Toyota. I interpret that as meaning the lifetime expected is decreased if you do not change the fluid around every 10-12 years or 60,000-80,000 miles. Dislike the trend of fewer dipsticks and gauges. Prefer old-school cable driven parking brakes.

[@blademan7671]

3rd reason: cost. Dealer service manager told me in 90s, their German brand had extended oil change interval from 7500 to 15,000 miles, and no parts were changed. It was so the brand could do fewer oil changes under warranty. And 2/3 of that German brand cars are now leased.

Obviously modern engine manufacturing methods are more refined than they were even 30 years ago. But that doesn't mean the engine is 100% fully ready to go right off the show room floor. Yes the engine does still require some break in. Running upwards of 1000 miles then changing the oil will help the remainder of the engine's life to be extended.

when I bought my new truck I changed the engine oil at 500 miles then 1500miles then at 5000 miles and at every 5000miles after, just to flush out the break in particles at 100k it still runs great and uses no oil between changes. I also replaced the differential oil at 5000 miles it came out very black and smelly like you would expect, but then when I changed it again at 20k it looked like new gear oil, and still looks new at every subsequent change, not a lot to spend for the great service life.

Chris, you can touch oil and have no concern. If you feel safer using gloves then use them. I sometimes do and sometimes do not. As far as the 5k goes, sounds about right if you are using synthetic oil. But if your engine noise is changing that's not a good sign. And never, ever, ever go by what the oil monitor says okay? Go by the mileage only.

But after a few thousand miles it all settles down. I change my oil multiple times during this period to give my engine the best chance possible oil is cheap. None of my cars burn any oil and all run perfectly I think it is a worthwhile step to do when the car is new.

I grew up around cars, my dad had a small Fiat dealership in the late 70s then a small Mazda dealership in the 80s when I was a kid. Back then, everyone knew that engine break-in was a thing and buyers were instructed to watch their driving at first and come back for an early oil change, it was just something you’d do with a new car. In the early 2000s I was a new car salesman, I sold Saturn, Saab, Isuzu, then Volkswagen. The majority of new car were leased. I’ve attended manufacturers trainings and asked them all what the break-in period was. All of them said there was no break-in period anymore, that was a thing of the past, modern engines were machined better, used better metallurgy and were broken in on test beds at the factory before being installed in cars on the assembly line. I always suggested to my customer to drive easy at varying RPMs the first 300 km and not go over 3,000 RPMs the first 1,000 km, then follow the manufacturer’s recommended schedule for oil changes as the first couple of oil changes were free. I did that too with my own new cars, but knowing what I know now thanks to this channel, I’d change it earlier and even more regularly. My last non-turbo 2.0L Volkswagen started burning oil quite early.

I was taught to suck the oil sample from the middle of the oil well and not from the drain..

Great video, thank you. Just bought new 24 Corolla hatchback , built in Japan and I love it. Uses 08-w oil. I just don’t get all The arguments with oil, cheapest thing to maintain in your car. I’m actually getting ready to do its first oil change 1k like you said. Then again at 5k miles and 3k miles thereafter. Many will say I’m pissing away money but that’s ok ✅.
