The AMSOIL Online Product Application Guide gives you fast, easy access to more than 20 years of vehicle data.

AMSOIL Formula 4-Stroke Synthetic Motor Oil SAE 0W-40 is specially formulated for four-stroke recreational motors, including ATVs, outboard motors and recreational motorcycles. It may also be used in cars and trucks. Its broad viscosity range makes it excellent for use in both hot and cold temperature extremes.

(Product Code: AFF)

AMSOIL Formula 4-Stroke Synthetic Motor OilSAE 0W-40 may be used in all applications specifying 0W-40, 5W-30, 10W-30 and 10W-40 viscosity grades and is recommended for applications requiring the following specifications:

API SJ, SH, SG, SF, CD, CF
JASO MA

Note: Harley and V-Twin motorcycles require the use of AMSOIL AMV and AMF Synthetic Oils. Click here for additional information.

AMSOIL AFF 0W-40 is ideal for 4-cycle snowmobiles, ATV’s, personal watercraft, 4-stroke boat motors, and lawn equipment.

AMSOIL AFF 0W-40 can be used in in any gasoline 4-stroke automobile engine. Recommended change intervals are at 7500 miles, or 6 months. AMSOIL AFF can also be used in diesel powered cars or trucks, with change intervals as recommended by your vehicle manufacturer.

Product DescriptionAMSOIL Formula 4-Stroke Synthetic Motor Oil SAE 0W-40 is specially formulated for four-stroke recreational motors, including ATVs, outboard motors and motorcycles. It may also be used in cars and trucks. Its broad viscosity range makes it excellent for use in both hot and cold temperature extremes. Resists High Temperature Vaporization Conventional motor oils tend to vaporize and lose weight in high temperature conditions, contributing to poor oil circulation, reduction in fuel efficiency and excessive emissions and engine wear. AMSOIL Formula 4-Stroke Synthetic Motor Oil is highly resistant to evaporation. While conventional petroleum oils thicken due to evaporation, AMSOIL Formula 4-Stroke Synthetic Motor Oil maintains its viscosity in high temperature service. The superior evaporation resistance of AMSOIL Formula 4-Stroke Synthetic Motor Oil keeps engine wear, oil consumption and emissions to a minimum, while keeping oil circulation efficient and fuel economy high. Friction Modifier Free AMSOIL Formula 4-Stroke Synthetic Motor Oil contains no friction modifiers, making it ideal for ATV, outboard motor and motorcycle engines. The friction modifier free formulation of AMSOIL 4-Stroke ensures transmission (manual or automatic) and clutch compatibility and prevents slip. Performance Formulated AMSOIL Formula 4-Stroke Synthetic Motor Oil contains a robust dispersant/detergent package, making it ideal for use in high-stress four-cycle engines. The dispersant/detergent additive package effectively suspends harmful combustion by-products and prevents deposits, keeping AMSOIL Formula 4-Stroke clean and serviceable. High-temperature operations often lead to the thermal degradation and oxidation of conventional oils, leading to the formation of deposits, sludge and varnish. The superior oxidative and thermal stability of AMSOIL Formula 4-Stroke Synthetic Motor Oil inhibits the formation of varnish, deposits and sludge so equipment runs clean in high-stress, high temperature operations. Temperature and Performance AMSOIL Formula 4-Stroke Synthetic Motor Oil SAE 0W-40 has a broad viscosity range, making it excellent for use in both hot and cold temperature extremes. As an SAE 40 weight motor oil, AMSOIL Formula 4-Stroke provides superior protection for hot operating, hard working motors, while its SAE 0W rating ensures easy cranking, excellent cold weather starting and quick post-startup protection. Copper Corrosion, Rust and Foam Inhibition AMSOIL Formula 4-Stroke Synthetic Motor Oil protects equipment from copper corrosion and rust, even during equipment storage. AMSOIL Formula 4-Stroke Synthetic Motor Oil does not foam in service, protecting equipment from the metal-to-metal contact and wear that occurs with use of foam-filled fluids. Applications and Recommendations AMSOIL Formula 4-Stroke Synthetic Motor Oil may be used in all applications specifying 0W-40, 5W-30, 10W-30 and 10W-40 viscosity grades and is recommended for applications specifying the following:

API SJ, SH, SG, SF, CD, CF
JASO MA

Use in Yamaha®, Suzuki®, Honda®, Mercury®, Kawasaki®, Arctic Cat®, Polaris®, Nissan® and Bombardier® motors and transmissions. Safe in wet or dry sumps. Recommended for manual or automatic clutches. Compatibility AMSOIL Formula 4-Stroke Synthetic Motor Oil SAE 0W-40 is compatible with other four-stroke fluids. However, a mixture of AMSOIL Formula 4-Stroke Synthetic Motor Oil and another oil may offer a shorter service life than pure AMSOIL Formula 4-Stroke Synthetic Motor Oil. AMSOIL Formula 4-Stroke Synthetic Motor Oil is compatible with and recommended for use with clutch plates in ATV’s and motorcycle transmissions. Installation Change AMSOIL Formula 4-Stroke Synthetic Motor Oil according to manufacturer’s recommendations, without oil filtration. With oil filtration (AMSOIL SDF Filter), up to 2 times longer than manufacturer’s recommendations or 6 months, whichever comes first. If a Hastings or other filter is used, filter should be changed at manufacturer’s recommendations.
