AMSOIL Recommended Oils For Harley Davidson Motorcycles

AMSOIL 20W-50 Synthetic Motorcycle Oil (MCV) is recommended for Harley-Davidson, Buell, Victory, Ducati, BMW, Aprilla and Triumph motorcycles calling for a 15W-50 or 20W-50 viscosity, providing superior protection in engines, transmissions and primary chaincases.

AMSOIL 10W-40 Synthetic Motorcycle Oil (MCF) is recommended for Honda, Kawasaki, Yamaha, Suzuki, BMW, Husqvarna and KTM motorcycles calling for a 10W-40 or 20W-40 viscosity, providing superior protection in engines and transmissions.

Improved Transmission Protection
Our SAE 20W-50 Synthetic Motorcycle Oils provide the full protection to the motorcycles' engines. Moreover, they also give protection for gear that meets to the requirements of API GL-1 gear lube viscosity. In two-cycle transmissions, you can use Synthetic 10W-40 oil.



AMSOIL Synthetic Motorcycle Oils exhibit higher HTHS viscosities than competing conventional and synthetic motorcycle oils. As seen in the graphs, AMSOIL Synthetic 20W-50 and 10W-40 Motorcycle Oils displayed the highest High Temperature/High Shear viscosities in their respective test groups, providing motorcycle engines and transmissions operating in the harshest conditions with superior protection against wear and viscosity loss and eliminating the need for separate gear case oils as recommended by some competitors. Synthetic 10W-40 may also be used in two-cycle transmissions.

Excellent Wet Clutch Performance
We supply the best quality AMSOIL motorcycle Motor oil which doesn't contain any friction modifiers. These oils are best for positive clutch and promoting smooth shifting. They not only control heat, but they also prevent glazing and slippage.

Excellent Corrosion Protection
Our Amsoil 20w50 Motorcycle Oil shows no sign of corrosion and rust as it is formulated with specialized additive technology. These oils not only protect at storage time, but they also protect against acids and corrosion during operation.

Outstanding Heat Resistance
AMSOIL motorcycle oils are very beneficial for hot running air cooled motorcycle engines. These engines have high temperature when they are idle in traffic. In common, they reach temperature up to 240 degrees Fahrenheit.

Foam Control
Our best formulated oils are great for minimizing foaming for providing lubricating protection in the long term with high RPM conditions and high speed.

Robust Additive Levels
Including the anti-wear additive ZDDP, AMSOIL Synthetic Oils are recommended for on-road bikes. ZDDP is a very effective anti-oxidant and anti-wear which minimizes its level results in compromised shortened service and wear control. These oils are overtreated with best additive packages such as high levels of zinc, calcium, phosphorus and other oxidation inhibitors for extending oil life expectancy.

AMSOIL Synthetic Motorcycle Oils are recommended for twice the manufacturer's recommended drain interval for on-road motorcycles.

The Four Ball Wear Test (ASTM D-4172) determines the wear protection properties of a lubricant. The smaller the average wear scar, the better the wear protection provided by the lubricant. AMSOIL Synthetic Motorcycle Oils produce significantly smaller wear scars than competing motorcycle oils, providing unsurpassed protection against engine wear, reducing maintenance costs and extending equipment life.

Cost Effective
We offer top quality AMSOIL Synthetic Motorcycle Oils with cost-effectiveness to competing with other motorcycle oils. These oils provide the best performance and unmatched protection to luxury bikes and custom motorcycles.
