AMSOIL 15W-60 and 20W-40 Synthetic V-Twin Motorcycle Oils are engineered to deliver maximum performance and protection for Indian* and Victory* motorcycles as a premium alternative to manufacturer-branded oils.

Fight V-Twin Engine Heat

Summer riding can cause engine temperatures to skyrocket, especially in slow-moving rally or parade traffic. The oil plays a vital role in dissipating the immense heat generated by big V-twin engines, especially air-cooled models. High heat can cause pistons to expand, leading to potential cylinder wear and scuffing. Plus, every 18°F increase in temperature doubles the speed your oil breaks down, leading to thinner, less protective oil combined with performance-robbing deposits and sludge.

AMSOIL Synthetic V-Twin Motorcycle Oil is engineered to exceed industry standards for high-temperature stability and deliver superior wear protection for critical engine components during high-heat operation. It is extremely resistant to thermal breakdown to prevent the formation of damaging sludge and carbon deposits that reduce engine performance. This means your bike will continue to perform flawlessly, even in stop-and-go traffic on the hottest summer days.

Easier Shifting

Smooth shifting makes riding easier and more enjoyable. Since most bikes share oil between the engine and transmission, they require a wet-clutch-compatible formulation without friction modifiers that promotes smooth, easy shifts and helps you avoid stalling the engine.

AMSOIL Synthetic V-Twin Motorcycle Oil is shear stable, so it resists thinning from mechanical activity like shifting gears, providing superior wet-clutch performance, while enhancing transmission and engine protection. Its ability to prevent slippage and glazing delivers the confidence of quiet, consistent and smooth shifts with positive clutch engagement, so you can’t blame that missed shift on your bike anymore.

Corrosion Protection

Motorcycles exposed to limited operation and extended period of storage are more likely to experience rust and corrosion that can increase engine wear and cause compression loss that reduces performance. Corrosion resistance is not natural to motor oils, so AMSOIL Synthetic V-Twin Motorcycle Oil is formulated with enhanced anti-rust agents for upgraded protection.

Extended Drain Intervals

When paired with a highly efficient AMSOIL Motorcycle Oil Filter, AMSOIL Synthetic V-Twin Motorcycle Oil protects your bike for up to 2X the manufacturer-recommended drain interval, so you can ride longer and farther between oil changes.


AMSOIL Synthetic V-Twin Motorcycle Oil is backed by the AMSOIL Limited Warranty and is Warranty Secure, keeping your factory warranty intact.
