Engineered to outperform all conventional gasoline engine motor oils. Reduce heat, friction and wear for maximum power, performance and fuel efficiency. Clean engine formula. Resists high temperature break down that forms sludge and varnish. Lasts longer and offers better protection. Ideal for hot and cold climates.
AMSOIL 100% Synthetic motor oil delivers extraordinary lubrication in all types of automotive gasoline engines. By combining the industry-premier synthetic technology with AMSOIL premium additives, AMSOIL ASL exceeds the higher performance demands of modern engines. It withstands the stress of higher horsepower, higher heat and complicated emission control systems. AMSOIL Synthetic Motor Oil is engineered to outperform competitive conventional and synthetic motor oils. It delivers long-lasting performance and protection.
AMSOIL SYNTHETICS, 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.
AMSOIL Extends Drain Intervals
AMSOIL Synthetic 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 Motor Oil is designed to deliver the best possible engine protection, cleanliness and performance over extended drain intervals, reducing vehicle maintenance and waste oil disposal costs.
AMSOIL Maximizes Fuel Economy
AMSOIL Synthetic 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.
AMSOIL Reduces Engine Wear
AMSOIL Synthetic 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.
AMSOIL Reduces Oil Consumption and Emissions
Volatility (burn-off) occurs when oil gets hot, causing high oil consumption and emissions. AMSOIL Synthetic 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).
AMSOIL Excels in Extreme Temperatures
AMSOIL Synthetic 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 Motor Oil contains no wax. It stays fluid down to -58°F for improved cold temperature oil flow, reduced bearing wear and easier starting
