Engine oil Shell or AMSOIL

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.

Using rotella t4 btw.

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.

Shell rotella t5 its valvetrain runs much smoother and quieter with a thicker diesel oil.

I only use Rotella T6 in all 6 of the cars at my house.

I've used Rotella T6 in literally all of my bikes since 2017 because it is cheap and has JASO MA2, it is deisel oil.

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.
