Engine break in.
- Thread starter JeepJKU85
- Start date
People quote cars from the 80s 90s saying change the oil at 500 miles. Oil was crap back then. Haven't really seen any info proving doing that does anything really except get rid of the assembly lube. GM still says you have to do it in the Corvette so maybe yes, so says GM.
I would let it go 2000 or so myself
Another 2,000 miles for me also,,,,,

A small smattering of the topic already covered ...
Keep or change filter-new car, changing out break-in oil?
Brand new '21 Mazda CX-5 non-turbo. Changing the oil at about 600 miles to get the metal sparkles out. As the factory Japanese filter is well regarded, should I keep it on until I change the next time (at 3500-4000 miles)? It's said that a partially used filter works better than new.

Break-in gasoline (or diesel)
We hear plenty about speciql break-in oils and driving procedures. But is there anything we can do to optimize the procedure with the fuel used in our engines?

should break in oil be thick or thin?
i think its thin but not sure, does anyone know and why.

Ok I posted it, then tried to delete it. I wasn't sure if it should stay bc this has been posted before. Couldn't find it though. http://www.mototuneusa.com/break_in_secrets.htm [ December 06, 2004, 06:45 PM: Message edited by: buster ]

Break-in oil myth or truth..............
First off I was referred to this site and it's a great site...........TONS of info and opinions. lol! I recently bought a new F-150, it has 2,000 miles on it. I have not changed my oil for the first time yet. I questioned someone about first oil change mileage and I was told that it didnt...

Watch this, then make your decision.
I'm kind of in the same boat. I have a 2024 Chevy Trax with 500 miles. My gut tells me to change it early, but I probably won't. I'll probably hit 3,000 to 4,000 miles in 6 months so that will be my interval. The vast majority of vehicles never get an early oil change and I doubt there is any proof doing an early oil change extends engine life. If I were interested in tracking wear metals I'd do a series of uoa's starting early, but I'm not so I won't.
I doubt very many Toyota Corollas get a first oil change at 500 miles and I seriously doubt it would make any difference in a Toyota 4 cylinder in terms of engine life.

What's the difference between doubt and seriously doubt?
To get your point across try SERIOUSLY DOUBT.
Or; WRITE THE WHOLE SENTENCE IN CAPS!!!! complete with exclamation marks.
I know of two 2013 Toyota Matrix and one 2010 Yaris that all got their first oil change(s) before 1,000 kms.
Add to that several other new vehicles, lawnmowers, garden tractors, snow blowers, pressure washers etc.
The new oil drained from these engines always have glitter and a metallic color, leaving behind metal flakes in the drain pan.
A break-in oil is one that has elevated anti wear additives to quickly coat the engine parts that contact each other.
Those break-in oils may increase friction and reduce power and fuel economy, so it may be beneficial to drain them early.
No need to change oil at 500 miles unless specifically stated by the manufacturer. Adhere to the owner’s manual if there is anything regarding driving speeds and RPM for the first xxx miles. Most of the world’s population drive a new car like they drive when its got 60k miles to include oil change intervals without issue. It’s the .00001 percent like BITOG group that even give it a second thought.
no break in oil just some assembly lube lol.
I was always a 1,000 mile changer on a new vehicle.

Oil is cheap, I think if you can get any machining junk out by doing an early oil change of 1K it is a good thing.

I generally will do my first oil change at around 800-1,200 miles. And then my next is around 4,000...after that I settle into my usual regimen.
But that doesn’t mean I’m doing it right, no one I think really knows. I’ve run into techs that say to let it go till 3,000 to let the factory oil really work into the camshaft lobes (high moly). And I’ve heard people say to get it out of there right at the 500 mile mark to rid the engine if the break-in metals. I choose the happy medium.

kia told my father to come in at 5k for an inspection and tire rotation, told him see you at 10k for the oil change. 
Leave it until the first OCI. Assume you bought the vehicle used with 20K miles and it received 5K OCI’s but not the break-in early dump… would you truly care?
If the manufacture states to change oil at 5,000 mi for sever service then I change the FF at 2,500 and again at 5,000 and every 5,000 after that. I try to not over think and complicate things for no good reasons. Ed
Just a note on pre filling oil filters. His video shows the oil filter slanted. If your new car has electronic throttle you can depress the accelerator past 80% when turning over the engine. That will prime the oil filter without starting the car.
