AMSOIL Formula 4-Stroke Power Sports Synthetic Motor Oil is specially formulated for ATVs, UTVs, snowmobiles and other powersports 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 Formula 4-Stroke Power Sports Oil provides outstanding protection for hot-operating engines, while its 0W rating and -60°F pour point ensure easy cranking, excellent cold-weather starting and quick post-startup protection. Formula 4-Stroke Power Sports Oil 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 Power Sports 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 Power Sports 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 Wear Protection
AMSOIL Formula 4-Stroke Power Sports 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 Power Sports Oil controls foam, promoting cooler engine operation and reduced wear.
Special Additives
AMSOIL Formula 4-Stroke Power Sports 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.
APPLICATIONS AND RECOMMENDATIONS
AMSOIL Formula 4-Stroke Power Sports Synthetic Motor Oil is recommended for four-stroke engines. It is also recommended for transmissions in two- or four-stroke 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 powersports equipment. Also recommended as a replacement for Polaris Synthetic PS-4 Plus and Arctic Cat Synthetic ACX. Manufacturers include Polaris®, Honda®, Yamaha®, Ski-Doo®, Can-Am® (Bombardier®), Suzuki®, Kawasaki® and Arctic Cat®.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, The First in Synthetics®, to do the best job protecting your engine.
What does AMSOIL say about the OEM 50WT oils out there Polaris and Arctic Cat recommend?
AMSOIL Magazine: Moving on to ATV applications, why does AMSOIL recommend Formula 4-Stroke® Power Sports
Oil (0W-40) in applications that call for OEM-labeled 50-weight oils?
Len Groom: As the graph shows, while Polaris Synthetic PS-4 Plus and Arctic Cat Synthetic ACX motor oils fall within a 50-weight viscosity range directly from the bottle, both quickly shear down into the 40-weight range. AMSOIL subjected both oils along with Formula 4-Stroke Power Sports Oil to ASTM D-7109
shear stability testing, and after only 30 passes, both OEM labeled oils sheared out of their starting viscosity grades.
After 90 passes, the Polaris oil lost over 33 percent of its viscosity, while the Arctic Cat oil lost over 30 percent. The AMSOIL product, however, lost less than 5 percent. Its exceptional shear stability allows it to protect high-RPM ATV engines as well as or better than both 50-weight OEM oils.

| As mentioned in the above article – Polaris’s Synthetic PS-4 2W50 is nothing more than an effort to confuse and hold customers to the OEM oil. When examined the quality fails to a 40 weight anyway. Choose the real synthetic guaranteed to protect your engine. AMSOIL’s performance will impress. Try us and see why! |
I don’t know where to start but this single product has produced more positive local feedback than any other product I stock other than the PI Fuel additive. It just goes to show the difference in brands.
I have many customers from Texas to South Dakota who comment on the high and low temperature improvements since switching. In Texas especially in Yamaha ATVs the AMSOIL really makes them run smooth when they get hot. No more vibrations. In South Dakota the low temperature properties have people saying their ATVs just feel ready to work right at start-up which has brought us a lot of new customers.
The #1 comment on our synthetic ATV oil is regarding how smooth the engine runs. Almost if they didn’t notice the vibration till it was gone. I sum it up as the engine is really running as it was meant to for the first time. With AMSOIL you enjoy base stocks which really hold the moving parts in suspension. That said, AMSOIL AFF ATV oil may be even better for that engine with high wear – Amsoil will make up for the poor viscosity retention the OEM brands exhibit.
It’s not always about the tests and ratings – I rate the products by the customer feedback – more power and better throttle response is just what AMSOIL does. Trust the company who specializes in “Better than OEM Performance!”
One Honda ATV owner had some severe trouble with shifting until he switched to AMSOIL 0W40.
Some of the other lads in that forum mention their use of Rotella T Synthetic which is a diesel oil. The posts were in 2006, but what they may not realize now that in 2007 the diesel oil anti wear additive packages and detergents is no longer enough for these types of powersports applications. Diesel CJ4 ratings are designed for specific engine changes which were mandated by the EPA that year. ATV engines must have the higher zinc and detergent levels as they operate under different RPM and temperature extremes.
