Reduces Friction, Heat and Wear
In high heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.
Smooth, Confident Shifts
AMSOIL Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting longer clutch life.
Controls Foam
High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.
Delivers Superior Rust and Corrosion protection
Motorcycles are prone to rust from storage, humidity and short drives. Rust can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good rust protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection. With its high 11.1 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.

Reduces Heat and Protects Against Wear
Motorcycles are often driven aggressively and in stop-and-go conditions. This scenario increases engine heat, especially during hot weather. Elevated heat breaks down mineral oils, reducing their ability to protect against wear. For maximum performance, motorcycle owners need a motor oil designed to resist extreme heat; guard against wear; and provide smooth, confident shifts. AMSOIL 100% Synthetic 4T Performance Motorcycle Oil is formulated for the high temperatures common to air-cooled V-twins, aggressively driven sport bikes and daily drivers operating in the most severe conditions. It delivers the confidence and security that come with outstanding protection and performance.
Reduces Friction, Heat and Wear
AMSOIL 4T Performance Motorcycle Oil’s high-quality synthetic base oils naturally reduce friction better than mineral oils. Its outstanding high-temperature film strength and anti-wear additives reduce engine and transmission wear regardless of operating conditions. It is thermally (heat) stable and contains oxidation-inhibitor additives that help maintain proper lubrication, even in extreme heat. AMSOIL 4T Performance Motorcycle Oil’s excellent friction-reduction and heat-transfer properties help keep engines running cool.
Smooth, Confident Shifts
AMSOIL 4T Performance Motorcycle Oil promotes smooth shifting and positive wet-clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting long clutch life.
Excellent Engine Cleanliness
High-revving, hot-running motorcycle engines can accumulate performance-robbing engine deposits. AMSOIL 4T Performance Motorcycle Oil contains advanced detergency additives that help clean critical engine components, neutralize harmful acids and reduce deposits for maximum performance.
Helps Reduce Oil Consumption
Volatility refers to a lubricant’s tendency to evaporate when exposed to high heat. Motor oils that volatilize more readily lead to increased oil consumption, which requires motorcycle owners to frequently top-off their oil. Volatility also leads to increased oil viscosity, which negatively affects energy efficiency. AMSOIL 4T Performance Motorcycle Oil features low volatility, meaning it helps reduce oil consumption and maintains its viscosity for optimum performance.
Delivers Superior Corrosion Protection
Motorcycles are prone to corrosion from humidity and short drives. Corrosion can cause major damage, such as uncontrolled wear, compression loss and blow-by. Good corrosion protection, however, comes by design and is not natural to motor oils. Unlike many motorcycle oils, AMSOIL 100% Synthetic 4T Performance Motorcycle Oil contains special anti-corrosion agents that deliver superior corrosion protection. It provides outstanding protection from acid corrosion and helps maintain engine cleanliness.
