Should I Use AMSOIL V-Twin Primary Oil Or 20W-50 In My Primary Chaincase?

You can use either product with outstanding results. Many Harley-Davidson owners prefer to use AMSOIL 20W-50 Synthetic Motorcycle Oil for the convenience of a single product in the engine, transmission and primary chaincase. AMSOIL V-Twin 20W-50 is designed to provide the utmost performance and protection in all three components, so this is 100% acceptable. Many prefer the idea of using this dedicated primary fluid. The performance and protection of either option is identical so there is really no wrong choice.

Dependable Clutch Engagement

AMSOIL V-Twin Synthetic Primary Chaincase Oil is formulated to optimize clutch operation. Expect improved clutch operation as you ease away from standing starts. This product also prevents clutch slippage during hard acceleration and under exceptionally hot operating temperatures. This product is compatible with aftermarket Kevlar clutch plates.

Protects Against Metal-to-Metal Wear

Powerful wear control ingredients prolong the life of chains, gears and bearings. A shear-stable synthetic base oil maintains consistent viscosity over long mileage and heavy operation. Therefore,  chaincase components last longer.

Provides Cooler Primary Chaincase Temperatures

The hallmark of all AMSOIL V-Twin products is the ability to not only withstand hot operating conditions, but to actually promote cooler operation. This chaincase oil also resists thinning out under hot conditions, so protection is never compromised.

Mixing AMSOIL V-Twin Synthetic Primary Chaincase Oil With Other Brands

AMSOIL V-Twin Synthetic Primary Chaincase Oil is compatible with other brands of conventional, semi-synthetic and synthetic primary chaincase fluid. While you can safely mix AMSOIL Primary Chaincase Oil with other brands, this will reduce the drain interval and performance capabilities of this product.

Service Life of AMSOIL V-Twin Synthetic Primary Chaincase Oil

AMSOIL Synthetic Primary Chaincase Oil should be changed every 10,000 miles (16,000 km) or once per season (whichever comes first).
