Wear Defense for 4-Stroke Engines
The four-cycle engines of ATV’s and snowmobiles can often receive quite a thrashing. AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor Oil uses a sophisticated synthetic base oil and powerful anti-wear additives to protect from extreme heat, heavy loads and extended periods of full throttle operation.
Performs in Cold Weather
With a cold-pour-point of -51C (-60F), AMSOIL Formula 4-Stroke 0W-40 cranks easily in any weather and brings instant oil flow for fast start-up protection.
Ideal Oil for Turbocharged Snowmobiles
AMSOIL Formula 4-Stroke withstands extreme heat and resists deposit formation making it is ideal for use in turbocharged engines found on many of today’s 4-stroke snowmobiles. Suitable for models such as Polaris Turbo IQ and Arctic Cat 4-Stroke Turbo.
A Worthy Transmission Performer
Many ATV’s have manual transmissions that require a 4-stroke oil that can withstand the shearing of gears and also be suitable for wet-clutches. AMSOIL AFF 0W-40 is designed withstand transmission service as well as improve shifting by lowering friction. It does not contain friction modifiers, so clutch plate glazing is not a risk.
Off-Season Rust Protection
When your toys are put away for the season, AMSOIL 0W-40 contains powerful anti-rust and corrosion inhibitors to keep your engine internals pristine and free of rust damage.
Lower Oil Consumption
The shear stability and low volatility of AMSOIL AFF 0W-40 means that your oil level will stay steady and not thin out or boil off in hot conditions or under heavy loads.
Shear Stable
AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor Oil offers much stronger resistance to shearing versus 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.
Mixing AMSOIL 4-Stroke Synthetic Oil with Other Brands
AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor Oil is compatible with all other brands of conventional, semi-synthetic and synthetic 4-stroke engine oils. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL oil.
The use of any aftermarket oil additives is definitely NOT recommended.
Service Life for AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor Oil
AMSOIL Formula 4-Stroke 0W-40 Synthetic Motor Oil is recommended for oil change intervals as stated by the vehicle owner’s manual.
