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.
Extends Drain Intervals
AMSOIL Synthetic 5W-30 Motor Oil can extend drain intervals far beyond those recommended for conventional oils. Its unique synthetic formulation and long drain additive system are very stable, resisting oxidation and neutralizing acids. AMSOIL ASL delivers the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.
Maximizes Fuel Economy
AMSOIL Synthetic 5W-30 Motor Oil is designed to maximize energy efficiency for improved fuel economy. Unlike conventional oils, its uniform molecular structure helps it flow more freely and reduce friction between metal surfaces. Anti-friction additives are included to further improve energy efficiency.
Reduces Engine Wear
AMSOIL Synthetic 5W-30 Motor Oil provides outstanding anti-wear protection. It has excellent viscosity film strength to separate metal surfaces and robust anti-wear additives to further reduce wear in metal-to-metal contact regions for improved engine life.
Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Synthetic 5W-30 Motor Oil has the lowest volatility rate of the oils tested, making it the best at controlling volatility-related oil consumption and emissions (see chart below).
Excels in Extreme Temperatures
AMSOIL Synthetic 5W-30 Motor Oil resists thermal (heat) breakdown better than conventional oils. It is heavily fortified with detergent and dispersant additives to prevent sludge deposits and keep engines clean. And unlike conventional oils, AMSOIL ASL contains no wax. It stays fluid down to -58°F for improved cold temperature oil flow, reduced bearing wear and easier starting.

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.
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.
