Superior-Quality Oils, No Discrimination

Many oil companies produce specialty racing oils for elite groups and do not offer them to the general public. For instance, several popular oil manufacturers produce racing oils offered only to NASCAR racers. All AMSOIL synthetic motor oils are already formulated to a higher level of performance than competitors' oils, and AMSOIL Dominator 15w50 Synthetic Racing Oil is no exception, as proven in the Four Ball Test (see chart above). 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 and Brady Smith, are available to everyone.

Ideal for Street Rods, Muscle Cars and Other Vehicles with Flat-Tappet Cams

The high levels of zinc and phosphorus additives make AMSOIL Dominator 15w50 Synthetic Racing Oil ideal for street rods, muscle cars and other vehicles with flat-tappet cams.

Improved Lap Times and Longer-Lasting Equipment

AMSOIL Dominator 15w50 Synthetic Racing Oil's proprietary friction modifier provides reduced friction for maximum power and cooler engine temperatures, resulting in improved lap times and longer lasting equipment.

Protection from Startup to the Checkered Flag

AMSOIL Dominator 15w50 Synthetic Racing Oil's multi-viscosity design provides maximum protection in temperature extremes. AMSOIL Dominator 15w50 Racing Oil offers excellent cold-start protection and provides less drag when engine oil has not reached stable operating temperatures. It maintains superior film strength during high-temperature operation on the track.

Service Life

Extended oil drain intervals are not recommended for engines modified from the original manufacturers' design. Change oil at appropriate intervals in racing engines and where fuel dilution is a concern. Otherwise in stock, non-modified engines, follow original equipment manufacturers' drain interval recommendations or extend drain intervals when monitored by oil analysis*.
