Amsoil Dominator® 5W-20 Synthetic Racing Oil (RD20)

Maximum Horsepower

The excessive friction and heat of racing robs engines of power and longevity. Dominator is formulated with a proprietary friction modifier for 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

Protection From Startup to the Checkered Flag

Dominator provides maximum protection in temperature extremes. Its low pour point offers excellent cold-start 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.

The piston crown contains normal carbon, while the rings remain clean and functional. Note the absence of wear or scuffing on the piston skirt. The camshaft shows little-to-no scoring, bluing or wear after 3,000 miles of high-performance racing.

Commercial Availability

Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. All Amsoil synthetic Racing oils are already formulated to a higher level of performance than competitors' oils, and Amsoil Dominator Synthetic Racing Oil is no exception. It provides maximum performance and superior protection to all racers, regardless of their level of competition. The same Amsoil Dominator Synthetic Racing Oil that is used in the engines of Amsoil corporately sponsored racers, including Scott Douglas, Chad Hord and Brad Lovell are available to everyone.
