AMSOIL Formula 4-Stroke® PowerSports Synthetic Motor Oil (AFF) is specially formulated for ATVs, UTVs, snowmobiles and other power sports applications. Its broad viscosity range and wax-free formulation make it excellent for use in both hot and cold temperature extremes. As an SAE 40 weight motor oil, AMSOIL AFF provides outstanding protection for hot operating engines, while its 0W rating and -60ºF pour point ensure easy cranking, excellent cold weather starting and quick post-startup protection. Formula 4-Stroke® Power Sports is an extreme temperature lubricant that provides outstanding performance in high performance, recreational or work/utility engines.
AMSOIL engineered Formula 4-Stroke® PowerSports Synthetic Motor Oil to withstand the high temperatures of recreational engines. It effectively resists oxidation and oil vaporization to prevent carbon/varnish formation, control oil consumption and minimize exhaust emissions. AMSOIL AFF controls oil thickening for good fuel economy, and it keeps engines clean for peak operating efficiency.
AMSOIL Formula 4-Stroke® PowerSports Oil is wet clutch compatible and contains no friction modifiers, making it ideal for both two- and four-stroke ATV transmissions. The friction modifier-free formulation is designed to prevent clutch slippage, delivering maximum torque and power to the wheels - a critical feature for towing or high-horsepower engines. AMSOIL AFF meets the frictional requirements of JASO MA/MA2.
AMSOIL AFF is formulated with high levels of anti-wear additives that provide excellent protection for pistons, bearings and gears in transmission containing units, while its shear stable, SAE 40 viscosity delivers a thick lubricating film for an extra margin of protection in hard working engines.
Churning occurs in high RPM engines that can cause oil to foam, depleting its lubricating abilities and increasing heat and wear. AMSOIL AFF controls foam, promoting cooler engine operation and reduced wear.
AMSOIL Formula 4-Stroke® PowerSports Synthetic Motor Oil contains robust dispersant/detergent additives that effectively neutralize the high levels of acids and combustion by-products prone to small engines. And it is anti-rust fortified for superior rust prevention, which is especially important in seasonally or infrequently used power sports equipment.
AMSOIL Formula 4-Stroke® PowerSports is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed. Aftermarket oil additives are not recommended for use with AMSOIL motor oils.
Follow the equipment manufacturer's recommended drain intervals.
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

I use this in my Can Am Commander Max. It helped quiet the engine immediately and makes it run smoother. After 100 hours of use, the oil looks like I had just put it in the motor. The engine starts easier and runs smoother. I used Amsoil in every motor I have, including my Indian motorcycle.

oil you can run. Engine sounds better.
Transmission shifts like a dream. Clutch feels amazing. My ATV did not perform like this on reg oil. Even starts easier since the change over
