Engine Oil – AMSOIL 20W50 100% Synthetic V-Twin Motorcycle Oil (3.78L)

AMSOIL 20W50 100% Synthetic V-Twin Motorcycle Oil is a premium, fully synthetic oil specifically engineered for those who demand the absolute maximum from their machines. This oil is specified for V-Twin engines, transmissions, and primary chaincases, providing comprehensive protection in a single product.
 

Key Features and Benefits:

• "Three-in-One" Solution: This oil is unique because it performs exceptionally well in all three systems—engine, transmission, and primary chaincase. You no longer need to purchase three different products.

• Exceptional Heat Resistance: V-Twin engines (especially air-cooled models) reach extremely high temperatures. AMSOIL’s synthetic formula is designed to maintain viscosity stability even under extreme conditions—such as traffic jams, parades, or riding in intense heat.

• Maximum Wear Protection: A robust anti-wear formula and oxidation inhibitors protect cylinders, pistons, and transmission gears, extending the service life of your components.

• Wet-Clutch Compatible: The oil is fully compatible with wet clutches. It contains no friction modifiers that could cause clutch slippage, ensuring smooth and precise gear shifts.

• Storage Protection: Specialized additives protect the engine's internals from rust and corrosion during the wet season or long periods of storage.
