“A top seller of our AMSOIL Inventory! Amazing results for ATV and UTV riders in all temperature extremes.”
AMSOIL Formula 4-Stroke Synthetic ATV 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.
The 0W-40 is often selected as an upgrade from the other two ATV oils (10W-40 and 5W-50). Check our lookup guide which uses OEM owners manuals to match products for you, to see if that choice is available for your ATV or UTV
In addition to the information below, the throttling nature of ATV riders cause specific issues addressed by this oil. Also be sure to purchase our SEMA product of the year – QUICKSHOT to restore the intake system to a like new condition. Using Quickshot in a 1/2 dose also stabilizes fuel for up to 3-month storage.
AMSOIL 0W-40 ATV OIL
Resists Heat and Thermal Breakdown
AMSOIL engineered Formula 4-Stroke Power Sports Synthetic Motor Oil to withstand the high temperatures of recreational engines. ATV’s and UTV’s often have smaller sumps which cause the oil life to be significantly shortened. Thus why this product is unique! 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 ATV 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. This is where you will notice the performance over the life of the oil interval. Others sheer out early in their life which effects the overall feel and decrease in oil pressure.
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.
It’s easy for other oil companies to go real cheap here as these additives to make this blend work for the duration are costly. When performance and protection matter, AMSOIL is your only choice.
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.

Here are some testimonials from AMSOIL’s site:
We use it in our 4wheeler YFZ450 with exceptional results, no wear whatsoever.
I started using this product in my 2003 Polaris 330 Magnum.
Reduces heat and provides the startup lubrication I wanted.
I recently switched to Amsoil i use it on everything i have that uses oil and would never use anything without Amsoil name on it!! i just recently purchesedFormula 4-Stroke Power Sports Synthetic Motor Oil
for my 700 Yamaha Grizzly and am highly impressed so far, you barely can read the dipstick after some serious riding for the money and if your looking for Quality first rated oil look no further than Amsoil!
I use this 0-40 oil in my turbo snowmobile.
Knowing it’s excellent protective properties, I never concern myself with engine issues. Sled now has 11000 miles on it and runs as good as the day I bought it.
In the winter, I put this in my 2014 BMW K1600GTL. BMW recommended their 5-40w which is good too, however this Amsoil has a better rating and the lower viscosity allows for quicker pick up and I can actually hear the difference in the followers. In the summer I’ll run Amsoil’s Metric Motorcycle.
