PRODUCT DESCRIPTION

AMSOIL Formula 4-Stroke® Power Sports Synthetic Motor Oil (AFF) is specially formulated for ATVs, 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-start-up 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® Power Sports 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® Power Sports 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.

Shear Stable

AMSOIL AFF offers much stronger resistance to shearing than Polaris Synthetic PS-4 Plus and Arctic Cat Synthetic ACX. Both are 50-weight oils when new, but ASTM-7109 Shear Stability Testing shows that they lose over 30% of their viscosity very quickly. AMSOIL AFF is a better alternative as it resists shearing by losing just 5%, offering superior long-term wear control.

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® Power Sports 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® Power Sports 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, 10W-40 and some 50-weight oils for ATVs, snowmobiles and other power sports equipment. Manufacturers include Polaris®, Honda®, Yamaha®, Bombardier®, Suzuki®, Kawasaki® and Arctic Cat®.

Compatibility

AMSOIL Formula 4-Stroke® Power Sports 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.
