Racing engines are exposed to conditions far-beyond those found in regular automotive applications. So why use an engine oil designed for daily-drivers?

Long-Lasting Engine Wear Protection

AMSOIL Dominator Racing 10W-40 is designed to withstand the rigors of extreme shock loads, high-heat and extended periods at high-RPM. This product delivers consistent viscosity protection in the face of high-horsepower.

Racing engines can also be prone to fuel dilution. AMSOIL Dominator 10W-40 is designed to withstand fuel dilution without compromising wear protection.

Cooler Operation And Optimum Power Output

AMSOIL Dominator Synthetic 10W-40 Racing Engine Oil is designed to reduce friction. This delivers a two-pronged effect. This friction reduction maximizes power output making this oil an incredibly cost-effective upgrade.

Friction reduction also creates cooler operating temperatures. This allows for consistent performance and longer engine life.

Fast Cold-Start Protection

AMSOIL Dominator’s full-synthetic formula flows instantly at start-up. Your expensive engine will receive immediate oil circulation upon start-up.

A Genuine Professional-Grade Formula

AMSOIL Dominator Synthetic Racing Oil series is exactly the same product that is supplied to AMSOIL-sponsored race teams. Many other oil brands supply exclusive formulas to professional race teams that my not be available to the public.

  • Unleaded or leaded gasoline-powered engines
  • Alcohol-fueled engines

Mixing AMSOIL Dominator 10W-40 Racing Engine Oil With Other Brands

Dominator Synthetic 10W-40 Racing Oil is compatible with all other brands of conventional, semi-synthetic and synthetic motor oils. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL Dominator Racing Oil.
