PRODUCT DESCRIPTION
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 engines.

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
efficien
cy.

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.

Anti-Foam
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.

Special Additives
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®.

Compatibility
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.

Service Life
Follow the equipment manufacturer’s recommended drain intervals.
