Feature Thermal and oxidative stability - AMSOIL . synthetic motor oils resist formation of sludge, varnish, acids, deposits and other degradation products.
Benefit Engines stay clean, which helps them perform better, last longer and require fewer repairs.

Feature Consistent viscosity in high and low temperatures.
Benefit Easier cold temperature starting. Better high and low temperature protection, which helps engines last longer and require fewer repairs.

Feature Superior friction reduction.
Benefit Lower wear rate, which helps engines last longer and require fewer repairs. Improves fuel economy.

Feature Low temperature fluidity.
Benefit Easier cold temperature starting. Better wear protection in cold temperatures, which helps engines last longer and require fewer repairs.

Feature Low volatility - AMSOIL synthetic motor oils don't evaporate.
Benefit Reduced oil consumption. Better oil flow gives better fuel economy and better wear protection.

Feature Broad temperature range of application.
Benefit AMSOIL synthetic motor oils work safely and protect at higher and lower temperatures than conventional oils do.

Feature High TBN (diesel oils).
Benefit Reduces rate of engine corrosion, which helps diesel engines last longer and require fewer repairs. Increases oil service life, which reduces maintenance costs.

Feature Extended service life capability.
Benefit AMSOIL synthetic motor oils last longer than conventional oils do, which saves motorists money and reduces the environmental impact of used lubricants.
