Engine oil PENNZOIL or AMSOIL

Dominator is a excellent oil

Dominator is great in saws. The only issue is that I'm small saws especially, and at thicker ratios, like more oil than 40:1, some bike oils will not burn completely and will gum up mufflers, screens, piston tops. Mostly high performance racing oils.

Tie between Royal Purple or Pennzoil, choice usually based on availability or sales. I might slightly favor Pennzoil due to its connection with Shell as I exclusively use Shell 93 fuel for the additives.

Amsoil Z-rod. You need zddp or you can kiss your cam lobes good-bye.

My engine is happy with Pennzoil Platinum. No leaks and minimal oil consumption.

While any oil can work for your car, the current best option in the market is Pennzoil Ultra.

I run Amsoil in my 100% in my vehicles and lawn equipment. It’s synthetic, uniform, and has low volatility unlike petroleum based products. Less frequent oil changes.

I combine that with Pennzoil Platinum as there’s almost always a rebate for it. I paid $12 a jug after rebates for my last batch.

Amsoil did pretty good, it beat out everyone else from that project farm oil series.

I use Amsoil 0W-20 508/509.
