Engineered with carefully selected, higher-viscosity synthetic base oils to withstand the high heat and pressure common to high-performance and racing applications.
Anti-friction chemistry is race-proven to provide an extra measure of protection against piston scuffing and bearing wear.
OUTSTANDING CLEANLINESS

Optimized for maximum performance despite severe service.
Best 2 stroke oil on market in my opinion. Burns clean and doesn't gum up power valve.

Great quality 2 stroke racing oil. Besides the good quality oil the red color is beneficial when mixing gas/oil, you can tell that it’s mixed gas when it’s in a fuel can ready to go.
This stuffs great. Dosent goop a lover my bike at 50:1. Clean burning. Low piston wear. I’ve used AMS oil 2 cycle oil back in the lste ‘70’s at 100:1 ratio. Good stuff
Bottom Line

Thank you for the honest pricing. Since BelRay discontinued the MC1, AMSOIL Dominator 2stroke Racing Oil has been my premix oil of choice. When retailers and web sellers are jacking up the prices, I can count on you guys to sell my favorite product at an honest price. Thanks again, James Duncan
Been using dominator for 20 years. I ran and still run it in my 03 kx250. This was has been run from 200' to 11000' and i ran that bike on the same piston from the rebuild in 96 to the rebuild in 23/24. The cylinder still had some cross hatching and the crank was in excellent condition. Power valves had minimal carbon build up.
100% recommend dominator to everyone!
Bottom Line
Yes, I would recommend this to a friend.
