AMSOIL Metric Synthetic Oil for Motorcycles, Designed for Harsh Environments

Modern motorcycle engines today are highly sophisticated and require specially designed lubrication to operate efficiently. For example, engines that rev up to 10,000 RPM or higher can cause oil foaming, reducing the protective capability of the lubricant on engine parts. Motorcycle oil often serves a dual purpose, providing lubrication for the clutch while also enduring shear forces from the transmission, which can further diminish the oil's lubricating ability, resulting in awkward shifting.

Moreover, touring and adventure motorcycles designed for long cross-country trips require longer oil change intervals. The high temperatures from compact, high-performance engines can also cause the oil to break down quickly, forming sludge that diminishes the engine's performance and power.

Superior Protection and Performance

The advanced technology in AMSOIL Synthetic Metric Motorcycle Oil is specifically engineered to prevent oil breakdown under extreme heat and pressure, delivering maximum performance. This lubricant facilitates smooth shifting while simultaneously protecting the engine and transmission from wear, helping the engine run cleaner and cooler, and enabling effortless gear changes.

By optimizing engine responsiveness and performance, you will experience powerful acceleration and exceptional cornering capability. With oil change intervals extended to twice the manufacturer’s recommendation, you can confidently explore remote areas without worry.

Proven on the Road and Dyno-Tested

We installed AMSOIL 5W-40 Synthetic Metric Motorcycle Oil in a BMW R 1250 GS* and operated it vigorously on both paved roads and rough terrain. We then connected it to a dynamometer and pushed the engine to its limits. After 12,000 miles (twice the recommended oil change interval), we disassembled the bike and inspected the engine and transmission components for wear.
