AMSOIL - The Best Motor Oil

Why is AMSOIL the best motor oil?

Extensive testing against 10 competing conventional, synthetic and synthetic blend motor oils proves AMSOIL 10W-30 Motor Oil outperforms all competitors. Check the following benefits:

Extends oil life

The Thin Film Oxygen Uptake Test (TFOUT) is used to measure the ability of oil to resist breakdown when contaminated with the byproducts of combustion. In testing, AMSOIL Synthetic 10W-30 Motor Oil lasted the longest of all competitors. To the consumer, that means AMSOIL controls sludge deposits and extends oil life dramatically.


Maximizes fuel economy, reduces oil consumption & emissions

The NOACK Volatility Test measures the evaporation of lubricants in high temperature situations. All lubricants evaporate to some degree. Less evaporation is better. AMSOIL 10W-30 Synthetic Motor Oil showed the least evaporation of all the competitors and outperformed its nearest competitor by over 30 percent. AMSOIL is the best motor oil.

Protects against wear

The best motor oil prevents wear. The Four-Ball Wear Test measures the amount of protection oil provides. Testing proved that AMSOIL 10W-30 Synthetic Motor Oil provides better protection against wear than all other oils tested. With AMSOIL Synthetic Motor Oil, engine life can be extended and major repairs are often reduced. AMSOIL is the best motor oil.
Protects hot engines

Viscosity refers to how thick or thin oil is. To prevent wear, it's important for a lubricant to maintain its protective viscosity level under severe operating conditions. The High Temperature/High Shear Test measures a lubricant's viscosity under severe conditions. AMSOIL 10W-30 Synthetic Motor Oil displayed the best viscosity rating of all competitors. AMSOIL oil is the best motor oil.

Helps engines start easier

The Cold Crank Simulator Test determines the thickness (viscosity) of lubricants at low temperatures. The lower a lubricant's cold crank viscosity, the easier an engine will turn over in cold temperatures. AMSOIL Synthetic 10W-30 Motor Oil is one of the two best in the competition. AMSOIL is the best motor oil.


Improves cold weather startupThe Pour Point Test determines the lowest temperature at which a lubricant will flow. The lower a lubricant's pour point, the better protection it provides in low temperature service. AMSOIL 10W-30 Synthetic Motor oil remains fluid down to -58 F. Once again AMSOIL beats every competitor. AMSOIL is the best motor oil.


Reduces corrosive effects of contaminantsTotal Base Number (TBN) measures how well a lubricant can reduce the corrosive effects of acids over an extended period of time. AMSOIL Synthetic 10W-30 Motor Oil has the highest TBN of the tested oils. Once again, AMSOIL is the best motor oil.
