AMSOIL 15W-50 100% 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 only oil I run in my Ducatis

Running AMSOIL motorcycle oils for about 20 years has given me peace of mind to never worry about engine protection, running one year drain intervals, or any other oil-related issue.

15w50

Good oil for older Triumphs. I do wish Amsoil would offer a 10w50 for street motorcycles. Newer Triumphs specify 10w50 or 10w40, I prefer 10w50.
