Two-Stroke Engine Defense

AMSOIL Full Synthetic 2-Stroke Injector Oil withstands all of the abuse that recreational two-strokes can dish out. The low-friction formula and powerful anti-wear additives keep engine internals protected from metal-to-metal contact.

Fights Deposits on Engine Internals and Power Valves

Clean operation is vital to both snowmobile and outboard engines. Snowmobiles are often equipped with variable exhaust power valves that if fouled, can dramatically reduce performance. Outboards can be susceptible to engine deposits that can ultimately lead to engine failure. AMSOIL “AIO” Synthetic 2-Stroke Injector Oil’s clean-burning formula is loaded with detergents to keep snowmobile, personal watercraft or outboard engines running clean and at peak operation.

All-Climate Capable

Like all AMSOIL synthetic oils, temperature extremes are not an obstacle. AMSOIL AIO flows down to -53C (-63F), so there is instant start-up protection in all weather. On the other end of thermometer, AIO is designed to shrug off the extreme heat and heavy loads. Only a good synthetic oil can deliver equal protection in all weather.
