Engine oil OEM Toyota or AMSOIL

Been using amsoil for a little over a year now and it's really quiet.

Amsoil. My s2k burned just about every oil when I beat on it until I started using Amsoil.

Any major brand of the correct rating and viscosity will work.

That being said, I have an 05 that was used as a DD for 12 years. Short trips, 3 days a week. After 12 years and 47K miles, I added a aftermarket supercharger. Put another 20K on it, including trips to the drag strip and track days.

I then had it rebuilt with forged internals because I wanted higher boost and more power. When the engine was pulled apart and measured. There was no wear. The cylinders were still within factory specs as was the crank.

I had used Amsoil SS 0W-20 the whole time.

Amsoil in everything I ever owned. My 2017 RAV4 hybrid is sitting on 350k miles and still running strong.

I run amsoil in the engine and primary and redline in the tranny. No issues, my glide runs better on the amsoil then when I the syn3 in it

Here I am just dumping in Amsoil 5W-50 SSO because all I care about is shear wear protection and something content with high temp operation. 20,000 miles and not even a single psi drop in compression the whole time, don't even premix.

I've been using AMSoil 5W30 in my WRX since it was new (2003). Turbo is still good, and head gaskets lasted 17 years. I think it's worth the price.

I use Amsoil 0W20 but I’m a dealer. I have access to the test they run comparing it to Mobil and AC Delco stuff. The Amsoil is supposed to be better longer, but to me that comes down to your filter more than your oil.

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);

Just do it every 5,000 miles. It’s the standard for most vehicles. Unless it burns oil often, then maybe 3000miles. I have a 2019 camry se and I’ve done it every 5k miles. It’s currently at 96k miles, oil still looks golden and brand new before I change the oil after every 5k miles.
