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 -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.

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.

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.

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.

HEALTH & SAFETY

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).

Excellent protection

I purchased this oil for our Quads in an effort to move to "One Brand" of oil, for all of our machines. After very successful use in our diesels, it was a given. AMSOIL-the first in synthetics, work hard in their R&D program, I trust AMSOIL.

Great Stuff

Have heard of Amsoil for a very long time. Just prior to this desert season. I bought a 1 year subscription and purchased a bunch of different products for the quads and Rzr. I have been very pleased. My sons quad always overheats and shuts off usually once a trip. Hasnt happened since I have been using Amsoil. I will renew my subscription and use this stuff every season.
