Formula 4-Stroke® Power Sports Oil (AFF)

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 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®.

Formula 4-Stroke® 10W-30/SAE 30 (ASE)

AMSOIL Formula 4-Stroke® Small Engine Oil (ASE) is a robust formulation designed for hot temperature, severe service operation of small engines where routine maintenance is often difficult or infrequent. It is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Unlike conventional SAE 30 motor oils, AMSOIL ASE has a naturally high viscosity index and does not contain paraffin (wax). It has a -38°F pour point and qualifies for SAE 10W, making it an “all season,” multigrade lubricant with a wide operating temperature range. As an SAE 30 weight motor oil, AMSOIL ASE provides outstanding protection for hot operating engines. Formula 4-Stroke® Small Engine Oil is a commercial grade lubricant that helps improve productivity and reduce maintenance costs through superior engine protection.

Formula 4-Stroke® 10W-40 Synthetic Scooter Oil (ASO)

AMSOIL Formula 4-Stroke® 10W-40 Synthetic Scooter Oil (ASO) is formulated specifically to meet the special needs of today’s high-tech air- and water-cooled four-stroke motorized scooters, offering unsurpassed wear protection and friction reduction for longer equipment life and cooler operating temperatures. Its exceptional shear stability ensures consistent viscosity protection and provides additional protection for transmissions and gear boxes, while its friction modifier-free formulation ensures wet clutch compatibility and smooth clutch operation. A special anti-corrosion additive package provides long-term protection during periods of inactivity and storage.

SAE 60 Synthetic Racing Oil (AHR)

AMSOIL SAE 60 Synthetic Super Heavy Weight Racing Oil is designed for high horsepower racing engines, typically supercharged and alcohol-burning or nitro-fueled, and requiring a high viscosity oil to resist the thinning effects of fuel dilution.

AMSOIL Synthetic Super Heavy Weight Racing Oil is formulated specifically for wear protection and friction reduction in the extreme service conditions of racing.  It has been proven on-track to bring down high engine oil sump temperatures by 20 degrees F, which speaks directly to its ability to reduce friction, promote power and inhibit wear.
