20W50 - 4T Performance

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.

  • Cools hot engines
  • Protects against wear
  • Delivers smooth shifts
  • Promotes quiet operation
  • Cleans engine components
  • Provides superior clutch performance

Further Info

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.
