Keeping my race car running high RPMs with confidence. I have been using this for 2 years since engine rebuild. No pinging, oil pressure holding strong.
Because you requested it, we made it!! This is the newest in our racing oil lineup based on requests. It seems it may end up being the most popular because many impressed with the 15W-50 may want to switch to the 10W-40 synthetic racing oil for even better revving speed! I could have used this one quite a while back.
Multi-viscosity, shear-stable synthetic race formula engineered to maximize power while providing outstanding engine protection. Heavily fortified with zinc and phosphorus additives to protect critical surfaces in extreme conditions. Proprietary friction modifier maximizes power and reduces engine temperatures. Durable additive system is excellent for racing and street engines.

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.
DOMINATOR is formulated with proprietary friction modifiers to reduce energy lost to friction. It delivers maximum horsepower and cooler engine temperatures, promoting
improved lap times and longer-lasting components.
DOMINATOR provides maximum protection in temperature extremes. Its low pour point offers excellent startup 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* teams. DOMINATOR 10W-40 Synthetic Racing Oil is already formulated to a high level of performance. It provides maximum performance
and superior protection to all racers, regardless of their competition level. The same DOMINATOR Synthetic Racing Oil that is used in the engines of AMSOIL corporately
sponsored racers, including Bryce Menzies and Brad Lovell, is available to everyone.
Use DOMINATOR 10W-40 Synthetic Racing Oil in domestic and import high-performance racing engines where an SAE 40 viscosity
oil is suitable, including (not limited to):
If you are racing to win AMSOIL Dominator is KEY. If you are performing engine tests you want the engine to squeeze out all the power possible w/o added drag. The differences per Gail Banks is in the magnafluxing tests after the run! It’s that visible and drastic.
