PRODUCT DESCRIPTION
AMSOIL Dominator® Synthetic 15W-50 Racing Oil (RD50) 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 15W-50 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 15W-50 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 Racing Oil’s superior
additive technology provides unmatched durability in extreme
conditions. In addition, its high levels of zinc and phosphorus
additives make it ideal for street rods, muscle cars and other
vehicles with flat-tappet cams.

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 15W-50 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 15W-50 Racing Oil is recommended for
high-rpm, high-horsepower, turbo/supercharged, gasoline- or
alcohol-burning, nitro-fueled or nitrous oxide gas-injected
applications operated under severe conditions.
Applications include, but are not limited to,
the following:
• Asphalt Late Model • Dirt Late Model • Modified
Big Block • Ford Crate Late Model • Dodge Crate Late
Model • Endurance • Rally • Sprint •
