Fights Engine Wear
DOMINATOR Synthetic Racing Oil's durable formulation resists viscosity loss due to mechanical shear to maintain a strong protective oil film. It is heavily fortified with zinc and phosphorus anti-wear additives to provide additional protection against scuffing and wear in severe racing conditions.
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 longer-lasting components.

Excellent All-Temperature Performance
DOMINATOR provides maximum protection in temperature extremes. Its low pour point offers excellent start-up protection and provides less drag when the oil has not reached stable operating temperatures. At elevated operating temperatures, it maintains superior film strength. DOMINATOR's thermally stable synthetic chemistry resists the effects of intense heat common to racing engines to provide reliable protection for the duration of the race.
Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. For example, several popular oil manufacturers produce racing oils offered only to NASCAR teams. DOMINATOR Synthetic Racing Oil is already formulated to a high level of performance. It provides maximum performance and superior protection to all racers, regardless of their competition level. The same DOMINATOR Synthetic Racing Oil that is used in the engines of AMSOIL corporately sponsored racers, including Scott Douglas and Brad Lovell, is available to everyone.
DOMINATOR Synthetic Racing Oil is compatible with leaded and unleaded gasoline, diesel, alcohol, nitromethane and nitrous oxide.
