Engine oil VALVOLINE or AMSOIL

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.

Valvoline VR1 for the track car. Valvoline VR-1 is a very highly reviewed oil with a high zinc content to keep race engines running with very minimal wear.

I believe the final takeaway was that Valvoline Max protection was the best

I just switched to Valvoline EP 0w20 after using Mobile 1 all my life, for a very important reason...

...the easy to open top with a built in pour spout. So good.

For this reason I run Valvoline 20W-50 VR1 which has high zinc and phosphorus to deal with the extra loads the flat-tappets put on the camshaft vs roller tappets.

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
