Formula 4-Stroke® Powersports 0W-40 Synthetic Motor Oil

Formulated for Top ATV/UTV and Snowmobile Performance

AMSOIL Formula 4-Stroke Powersports Synthetic Motor Oil’s 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 Formula 4-Stroke Powersports Oil provides outstanding protection for hot-operating engines, while its 0W rating and -58°F (-50°C) pour point ensure easy cranking, excellent cold-weather starting and quick post-startup protection. Formula 4-Stroke Powersports Oil is an extreme-temperature lubricant that provides outstanding performance in high-performance, recreational or work/utility engines.

AMSOIL Formula 4-Stroke® Powersports 0W-40 Synthetic Motor Oil
  • Quick startup protection
  • Helps prevent carbon/varnish formation
  • Easy cold-weather starts

Resists Heat and Thermal Breakdown

We engineered Formula 4-Stroke Powersports Synthetic Motor Oil to withstand the high temperatures of recreational engines. It effectively resists oxidation and oil vaporization to help prevent carbon/varnish formation, control oil consumption and minimize exhaust emissions. It also controls oil thickening, promoting improved fuel economy, and it helps keep 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, helping deliver maximum torque and power to the wheels – a critical feature for towing or high-horsepower engines. It meets the frictional requirements of JASO MA/MA2 and ISO-L-EMA2.

Superior Rust Protection

Formula 4-Stroke Powersports Oil is formulated with high levels of anti-wear additives that provide excellent protection for pistons, bearings and gears in transmission containing units. 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 Formula 4-Stroke Powersports Oil controls foam, promoting cooler engine operation and reduced wear.

Special Additives

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. It is anti-rust fortified for superior rust prevention, which is especially important in seasonally or infrequently used powersports equipment.
