Engine oil AMSOIL or IDEMITSU

AMSOIL ALL THE WAY!!!

Coyote tick is practically gone and I’ve tried Motorcraft, Penzoil, Mobil, Royal Purple, & Castrol. Amsoil is a little more $ but 100% worth it.

Amsoil 10W-30 Signature Series here. It's on the expensive side but it's 100% synthetic, tests great, and made in the USA.

I have ran Amsoil since day one on my 2016. I change oil once a year currently sitting at 156,000 miles, no issues knock on wood.

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 think Idemitsu is the better option if you have access to it. Mostly because it was developed for the rotary engine.
