  • Formulated to resist viscosity loss
  • Engineered to maximize horsepower and torque
  • Fortified with anti-wear additives for extra protection.

Fights Engine Wear

DOMINATOR Synthetic Racing oil’s durable formulation resists viscosity loss due to mechanical shear to maintain a strong protective oil film. This oil is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe racing conditions.

Maximizes Horsepower

DOMINATOR is formulated with a proprietary friction modifier to reduce energy lost to friction. It delivers maximum horsepower and cooler engine temperatures, promoting improved lap times and long-lasting components.

Superior All-Temperature Performance

DOMINATOR provides maximum protection in temperature extremes its low pour point offers excellent startup protection and provides less drag when the oil has not reached stable operating temperatures. At elevated operating temperatures, it maintains superior film strength. DOMINATIOR thermally stable synthetic chemistry resists the effects of intense heat common to racing engines.
