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 -60°F 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
Resists Heat and Thermal Breakdown
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.
Excellent For Transmissions
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.
Superior Wear Protection
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.
Applications and Recommendations
AMSOIL Formula 4-Stroke® PowerSports Synthetic Motor Oil is recommended for four-stroke engines and transmissions
on two- or four-stroke powered applications. It is an all climate/all season oil that replaces 0W-30, 0W-40, 5W-30,
10W-30 and 10W-40 oils for ATVs, UTVs, snowmobiles and other power sports equipment. Manufacturers include
Polaris®, Honda®, Yamaha®, Ski-Doo®, Can-Am® (Bombardier®), Suzuki®, Kawasaki® and Arctic Cat®.

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.
