Engine oil OEM Toyota or RAVENOL

The car care nut says to do it, so I will trust him. My '24 Corolla SE Hybrid is at 802 miles and there is a 5 quart bottle of Mobil One Advanced Fuel Economy full Synthetic 0W-16 and a Mobil One extended performance high capacity filter waiting for tomorrows early oil change.

First 500-1000 miles is probably a good idea since there are likely metal bits left over from the manufacturing process and, although they get cleaned very well, the oil does a much better job of it and you don't want those bits floating around in yiur oil or in your engine itself.

After that, you can change your oil as often as you want as long as its under ~10k miles. Most people recommend 5k miles bc oil will pick up debris and metal shaving and what not and 10k is a bit long to let it go unless you're using a much higher quality filter like amsoil or Mobil 1. Most full synthetic oils will last longer than 10k miles these days, but I wouldn't push it due to the debris it picks up.

I got my first oil change at 1065 miles following Toyota Master Diagnostic Technician youtube personality The Car Care Nut's advice to do the first one at 1000 miles, and will follow a 5000 mile / 6 month schedule going forwards.

We haven\u2019t done anything but oil changes since buying it.

Even Ravenol, which is pretty expensive since it is made in Germany from Group V base stock. Great stuff.

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

I go with 10w40 Ravenol TSi

For newer vehicles I am in the camp of: if you want the car to last a long time use the 5K change interval with the exception being in the first 10 K. For the first 10K miles I would do 3 changes (not just 2) to be sure any debris/material from the break in process is cleaned/ cleared out quickly before it can potentially metastasize into a bigger issue (much later on);

I mistakenly put 0w20 in ~1000 miles ago, and though my engine hasn't fallen out while I driving I've seen ~5-10% loss in mpgs and it's a little louder than it was with 0w16.
