Engine oil Shell or AMSOIL

Amsoil is top tier oil and you can't go wrong with it.

I’m using Amsoil 0w-30 and am very pleased with it. Getting about 1 mpg better gas mileage and had the Amsoil lab analyzed after 3500 miles and numbers are better than what the factory oil showed. All added up, the Amsoil was better at protecting the engine.

I always buy engine oil from Lotus (Tesco). Shell Helix especially on sale.

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.

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

The same oil goes into all GDI engines at my dealer, which is Shell Helix Ultra SP 0W-20. This is a super expensive, latest spec oil. Oil changes with this oil are done at 9320 miles if turbocharged and 18 640 miles if naturally aspirated.

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 have a buddy that used the Shell Rotella diesel oil that is dirt cheap for his 2009 r1.

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