AMSOIL DOMINATOR 5W-20 Fully Synthetic Engine Oil

AMSOIL DOMINATOR 5W-20 is a fully synthetic racing engine oil engineered to maximize power while providing outstanding protection in high-rpm, high-heat and shock-loading conditions. Its shear-stable formulation resists viscosity loss, while high levels of zinc and phosphorus help protect critical surfaces in severe racing use. A proprietary friction modifier helps reduce friction for maximum horsepower and cooler engine temperatures.

Key Benefits

• Durable formulation resists viscosity loss due to mechanical shear to maintain a strong protective oil film

• Heavily fortified with zinc and phosphorus anti-wear additives for added protection against scuffing and wear in severe racing conditions

• Proprietary friction modifier helps maximize horsepower and torque while reducing engine temperatures

• Excellent all-temperature performance with strong film strength in extreme heat and strong start-up protection in cold conditions

Applications (Specifications / Approvals)

• Compatible with leaded and unleaded gasoline, diesel, alcohol, nitromethane and nitrous oxide

• Use in domestic and import high-performance racing engines where an SAE 20 viscosity oil is suitable, including (not limited to):

  • Modified small-block

  • Bracket

  • Asphalt late model

  • Midget

Change / Drain Interval (Service Life)

• Consider the event, application and viscosity needs. When competing, the vehicle owner is responsible for determining an appropriate oil service interval.

• Not intended for long-term use in passenger cars/light trucks.

Note: Always confirm the required viscosity and specifications in your owner’s manual or with your engine builder before use.
