AMSOIL 10W-40 100% Synthetic Metric Motorcycle Oil
  • Premium wear protection
  • Smooth, confident shifts
  • Cool, clean performance

Reduces Friction, Heat and Wear

In high-heat conditions, AMSOIL Synthetic Metric Motorcycle Oil exceeds the standard for high-temperature film strength to deliver excellent wear protection. It keeps engines running cool by effectively reducing friction and heat, and it contains a heavy treatment of anti-wear additives to reduce wear regardless of operating conditions. AMSOIL Synthetic Metric Motorcycle Oil is thermally (heat) stable and contains maximum levels of oxidation-inhibitor additives. It is extremely resistant to volatility and is engineered to prevent damaging sludge and carbon deposits for superior engine cleanliness.

Smooth, Confident Shifts

AMSOIL Synthetic Metric Motorcycle Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It is engineered to control heat and prevent slippage and glazing, promoting long clutch life.

Controls Foam

High-rpm operation causes some motor oils to foam. When foam bubbles travel between gear teeth or engine components, they collapse, allowing metal surfaces to contact, causing wear. AMSOIL Synthetic Metric Motorcycle Oil contains advanced anti-foam additives that help prevent foam, allowing riders to confidently push their bikes to the limit.

Delivers Superior Rust and Corrosion Protection

Unlike many motorcycle oils, AMSOIL Synthetic Metric Motorcycle Oil contains special anti-rust agents that deliver superior rust protection during storage and long periods of inactivity. With its high 11.6 total base number (TBN), AMSOIL Synthetic Metric Motorcycle Oil provides greater protection from acid corrosion and helps maintain internal engine cleanliness.

The perfect motor oil for my motorcycle

I have a 2005 BMW R1200ST, and I have used AMSOIL in it since it was bought new. It has had the oil condition checked by a lab at every oil change which is approximately 4k miles. The report I get back always states basically no wear on the engine. I also use the required lives in the transmission and final drive with the same reports. The leak down test also show close to 1.6% leak which for a almost 20 year motorrad I think is excellent. I will continue to use the suggested lubes for AMSOIL in all my vehicles like I currently do.
