AMSOIL DOMINATOR® Synthetic 5W-20 Racing Oil (RD20)
provides superior performance
and maximum protection in high-performance and racing
applications. DOMINATOR is engineered from advanced synthetic technology to better withstand the elevated rpm, high temperatures
and shock-loading common to racing applications. Its robust formulation,
tested and validated by championship race teams, is designed to
provide maximum horsepower without sacrificing engine protection.
DOMINATOR provides straight-grade protection in a multi-grade
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
Racing and high-performance engines are typically modified to deliver maximum
horsepower and speed. Their powerful designs create shearing forces that can cause
lesser oils to lose viscosity, leaving bearings, pistons and other components vulnerable
to wear and failure. DOMINATOR Synthetic Racing Oil's durable formulation resists viscosity
loss due to mechanical shear to maintain a strong protective oil film. It is heavily
fortified with zinc and phosphorus anti-wear additives to provide additional protection
against scuffing and wear in severe racing conditions (see results below).
|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.|
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
- 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
Racing is Research™
The AMSOIL Offshore Racing Team
has claimed many national and world
championship titles in several different
categories of racing, and AMSOIL
DOMINATOR Synthetic Racing Oil has
been key to its success. After a full racing
season covering 3,000 miles of extreme
driving, a teardown of one of the team's Mercury® 525 EFI V-8 engines revealed
clean, virtually wear-free components.
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.
Many oil companies produce specialty racing oils for elite
groups and do not offer them to the general public. For example,
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, Bob Teague and Erik
Buell Racing are available to everyone.
DOMINATOR 5W-20 Synthetic Racing Oil is recommended for modified small block, asphalt late model, bracket, midget and other domestic and import high-performance racing and street applications that require a 20-weight oil.
AMSOIL Ea® Racing Air Filters (EAAR) are specially designed
for racing and street rod enthusiasts who desire AMSOIL Ea
protection in carbureted applications. AMSOIL Ea Racing Air
Filters are constructed with the same synthetic nanofiber media
as other AMSOIL Ea Air Filters, providing maximum protection
and extended filter life.
AMSOIL offers WIX Racing Oil Filters for racing applications.
