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. Trust the extensive experience of AMSOIL The First in Synthetics®
to do the best job protecting your engine.
MAXIMUM DURABILITY,
MAXIMUM WEAR PROTECTION
AMSOIL Dominator Synthetic Racing Oil features
an additive package heavily fortified with zinc and phosphorus
for superior long-term wear protection. Designed for maximum durability, it ensures critical
engine components are protected for the duration of the race.
Dominator Synthetic 5W-20 Racing Oil’s superior additive technology provides unmatched
durability in extreme conditions. In addition, its light viscosity makes
it ideal for high-performance tuner cars and sub-compact vehicles.

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.
APPLICATIONS
AMSOIL Dominator
Synthetic 5W-20 Racing Oil is recommended for high-rpm, high-horsepower, turbo/supercharged,
gasoline- or alcohol-burning and nitrous oxide gas-injected applications
operated under severe conditions.
