Reduces Friction, Heat and Wear
The high-quality synthetic base oils in AMSOIL 4T Performance Motorcycle Oil reduce friction better than mineral oils. It is also thermally stable and contains antioxidant additives that help maintain proper lubrication, even in extreme heat. Its outstanding high-temperature film strength and anti-wear properties help minimize engine and transmission wear and keep engines running cool, regardless of operating conditions.
Promotes Smooth, Confident Shifts
AMSOIL 4T Performance Motorcycle Oil controls heat to help prevent clutch plate glazing and slippage, promoting positive engagement for smooth, confident shifts and extended clutch life.
Improves 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 neutralize harmful acids and reduce deposits for cleaner engine components and maximum performance.
Inhibits Corrosion
Environmental exposure can accelerate corrosive wear leading to compression loss and blow-by. AMSOIL 100% Synthetic 4T Performance Motorcycle Oil contains special anti-corrosion agents to inhibit corrosion and maintain maximum engine performance.
Reduces Oil Consumption
Volatility is a lubricant’s tendency to evaporate, leading to increased oil consumption and requiring additional oil between regular service intervals. Volatility also leads to increased oil viscosity, which negatively affects engine efficiency. AMSOIL 4T Performance Motorcycle Oil features low volatility and maintains its viscosity to reduce oil consumption and maximize performance.
