AMSOIL Dominator Racing Oil bottle, 10W-30.

AMSOIL DOMINATOR® 10W-30 100% Synthetic Racing Oil

AMSOIL DOMINATOR® 10W-30 Racing Oil is formulated to meet the demanding requirements of racing engines. It provides robust protection against the high stress and extreme conditions of racing, including elevated rpm, high temperatures, and intense wear. The oil’s advanced synthetic formulation ensures maximum horsepower without sacrificing engine protection, featuring a proprietary friction modifier for reduced energy loss due to friction. This leads to maximum power output and cooler engine temperatures, improving lap times and extending component life. The oil is heavily fortified with zinc and phosphorus anti-wear additives, providing additional protection against scuffing and wear in severe racing conditions. It offers straight-grade protection in a multi-grade formulation, making it suitable for a wide range of high-performance racing and street applications, including modified big block, marine, and sprint vehicles. AMSOIL DOMINATOR® 10W-30 is recommended for high-rpm, high-horsepower, turbo/supercharged, gasoline- or alcohol-burning, and nitrous oxide gas-injected applications operated under severe conditions.

DOMINATOR® Synthetic Racing Oil

AMSOIL DOMINATOR® Synthetic Racing Oil is designed to protect high-performance racing applications operating on the ragged edge. DOMINATOR is engineered to withstand the elevated rpm, high temperatures and shock-loading common to racing applications. Its robust formulation is lab-crafted to provide maximum horsepower without sacrificing engine protection and has it been tested and validated by championship-winning race teams. DOMINATOR provides straight grade protection in a multi-grade formulation.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics,® to do the best job protecting your race engines.

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.

Maximizes Horsepower

DOMINATOR is formulated with proprietary friction modifiers 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 startup 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.

Commercial Availability

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 Bryce Menzies and Brad Lovell, is available to everyone.
