Amsoil MC4 4-Stroke 10W-40 Motorcycle Oil MC4

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.

AMSOIL Synthetic Lubricants

AMSOIL specialises in premium synthetic lubricants, filtration products and vehicle maintenance fluids for automotive, motorcycle, four-wheel drive, marine, racing and industrial applications. Founded in 1972 with the introduction of the first API-qualified synthetic motor oil, AMSOIL has continued to develop high-performance products designed to provide exceptional wear protection, resist heat and oxidation and maintain performance under demanding operating conditions. The AMSOIL range includes engine oils, transmission and gear lubricants, greases, fuel additives, filters and specialised fluids for enthusiasts who demand more from their vehicles and equipment.
