Oil change interval

[MK5 GR]

I normally change oil on new motors at 1,500 miles but dealer refused to do it. So I told them I wanted it changed when it hits 3,000 and they said no to that as well. They claim the car will let me know when it needs to be changed. I am not real comfortable with this so what is everyone else doing. I can do it myself but exactly what oil and are y’all using Toyota filter or BMW or is there something better? Any additional additives like Molly etc. Thank y’all.

I bought the Supra oil from my Toyota Dealership in case I have to top it off. They have a 5L or 1L version.

As for the oil change, I changed it when the Supra said it was low. I don't remember how many miles but I think it was like 6-7k. My dealer also told me to not change it when I was at like 5k and wait until I was at 10k. However, when I told them the car was signaling it needed a change, they did it without hesitation.

Changed at 1200, 3000 & 5000 miles. Liqui Moly 5W-30. I get my filters from Amazon, don’t mind what the dealership says about intervals.

I used both my free changes done within the first 10K miles... break-in change was a late by my standards, but way early by BMW/Toyota guidance (I think it was at ~2500 miles). Everything after that was done at my local BMW shop, because Toyota sucks.

The dealership initially balked, but I told them they were doing a change regardless - if I had to pay out of pocket, so be it... after that no problem getting my "free" change. Remember when "customer service" meant something? Sigh.

Changed between 1,100 and 1,200 miles and used the same filter as @Loco38SUP and the same oil as @Hexel.

Do you have a link to this oil?

I changed mine at 1800 miles with this:

And I plan to change it every 5k with the same kit from here on out.

You guys need to realize that a dealership has to follow guidelines to get paid on warranty work. So I can understand them not always wanting to go outside service intervals.

You are actively throwing money away. 1,500 miles is absolutely insane for a modern synthetic oil its not 1975 anymore. Even 3000 is insane.

Change once per year or at 10k which ever comes first. If tracking it drain oil after 4-6 days at the track, if you are proper fast you may want to change earlier. Ill also only change the filter once per year even if I drain the oil multiple times due to being at the track.

Test your oil and listen to their recommendations, modern oil of most brands are very capable of going 10k+ miles. Get your oil tested by a lab at 1500 or 3000 if you are that worried but its going to come back as basically brand new at that mileage, keep increasing the mileage and test the oil to determine where it starts to drop and then change it earlier next time.

I dont drive more then 10k miles per year even in my daily. Tacoma gets changed once a year, Supra will get the same + track changes if needed. My race bike got changed every 4th race weekend, oil filter twice per year.

Changing oil and testing after break-in isn't uncommon. A lot of folks do this. After that, it really depends on how you use your car. Which leads me to:

f tracking it drain oil after 4-6 days at the track,

It's not uncommon for racers to change their oil after a few pulls at the track, though it really depends on what your oil is going through. A bunch of back to back 9sec passes and it's getting changed -for sure-. after a single track day.

On modern engines machining tolerances are so tight now that the engine breaks in damn near instantly. The crap in the manual is purely legal talking so you dont drive your new car like an idiot. Modern oil filters are like 99% efficient at 20 microns and 50% efficient at ~5 microns. Its seriously no longer required, a good practice? Depends on the metals used, bearing material chosen, etc. OEM engines? Not required at all. Custom race engine? Listen to your builder, some want break in oil and an oil change after the first pulls, some dont and want you to run normal oil and normal change intervals.

The main reason racers are changing oil after a pass or two is not because the oil is "done" so to speak its because fuel has contaminated the oil due to ring or valve guide blow by, this causes the oil to break down and fail much faster if its not removed. This is less likely during circut racing because the oil is much hotter for longer so it has time to bake off the fuel/water. Drag cars get hot and then cool, over and over again which is horrible for removing water and fuel.

I have more oil tests on several engines then most people will see in a life time. Most of them have been beat to shit on the track living the hardest lives. I change my oil when the labs say to change it. Even on the race track oil will last several hard sessions of driving without issues. The biggest killer of oil is fuel or water getting into it which labs also will test for.

Edit: If you are seriously worried about your engine turn off auto stop start, that is the biggest wear item on the whole car. OEMs are using a new type of bearing material just so the car can be turned off for 30 seconds when you come to a stop and the bearing oil pressure drops.

Modern oil is amazingly capable, no need to throw it out sooner then it needs to be.
