Product Description

AMSOIL Dominator® Synthetic 5W-20 Racing Oil (RD20) provides superior performance and maximum protection in high-performance and racing applications. Formulated to withstand the elevated RPM, high temperatures and shock-loading common to racing applications, Dominator Synthetic 5W-20 Racing Oil delivers superior performance and maximum protection in extreme conditions. Its shear-stable formulation was engineered to provide maximum horsepower without sacrificing engine protection. Dominator Synthetic 5W-20 Racing Oil 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.

Designed for maximum durability, it ensures critical engine components are protected for the duration of the race.

SUPERIOR PERFORMANCE

Dominator 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

Dominator Synthetic 5W-20 Racing Oil's multi-viscosity design provides maximum protection in temperature extremes. Dominator Racing Oil offers excellent coldstart 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.

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 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 and Brady Smith, are available to everyone.

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).

I like Amsoil prodoucts.

I have a '73 Bronco with a 302 V-8 engine. It has a mild flat tappet cam and a few other goodies. Because of the 'flat tappet cam' the engine needs oil with zinc. The Amsoil Z-ROD Syn. is exactly what the 302 ci. needs as it contains high levels of ZDDP for max. protection.

Great products for my business/shop.

I have been a long time Amsoil user myself for all my racecar/street car applications. When I opened my shop it was only fitting to stick with the best! All my customers cars/builds get Z-rod or Dominator series and with great results.
