Features and Benefits to Using AMSOIL synthetic oils Feature- Cooler operation. Benefit- Cooler engines resist stress and wear. They last longer, perform better and require fewer repairs. 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.
