Product Description

AMSOIL DOMINATOR® Synthetic Racing Oil provides superior performance and maximum protection in high-performance and racing applications. DOMINATOR is engineered to better withstand the elevated rpm, high temperatures and shock-loading common to racing applications. Its robust formulation, tested and validated by championship race teams, is designed to provide maximum horsepower without sacrificing engine protection. DOMINATOR provides straight-grade protection in a multi-grade formulation.

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 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.

• Formulated specifically for racing & high-performance engines
• Robust formulation resists viscosity loss
• Proprietary friction modifier maximizes horsepower & torque
• Fortified with anti-wear additives for extra protection

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.

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 Scott Douglas and Brad Lovell, is available to everyone.

Service Life

Consider the event, application and viscosity needs. When competing, the vehicle owner is responsible for determining an appropriate oil service interval. DOMINATOR is not intended for long-term use in passenger cars/light trucks.

HEALTH & SAFETY

This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

T/A using synthetic oil

I use it in a 1979 Trans Am with the Pontiac 400 CI engine with 53K miles. Seems to hold great oil pressure from idle to high rpms. I have not noticed the leakage of oil associated with the change from conventional oil to synthetic oil.

I will continue using this oil..

I use this product in my street rod, a 1930 ford with a 466 inch ford motor. I believe the oil is dewing its job but when I been submitting the oil for testing I am getting results that do not make sense. Other wise I will continue using this oil..

Nothing But the Best

I wouldn't use anything else in our racing engine. This engine had 300,000 miles on it when we put it in our racecar. Now, in the racecar, it's lasted 2 full seasons and still going strong.
