  • Superior all-weather performance
  • Wet-clutch compatible

Severe-Service Engine Protection

Many enthusiasts modify their ATVs or UTVs with roof and door panels, skid plates, winches, plows and other accessories that add weight and increase the severity of operation. Aggressive riding and tackling tough terrain place additional stress on the engine. Increased heat generated during severe-duty operation causes oils designed for standard service to break down sooner, increasing the risk for wear.

AMSOIL Synthetic ATV/UTV Motor Oil’s synthetic technology delivers reserve protection against heat. It provides reliable wear protection and aids in cooling shrouded engines.

Superior All-Weather Performance

AMSOIL Synthetic ATV/UTV Motor Oil remains fluid in sub-zero temperatures to provide excellent startup protection. It resists thinning due to extreme heat and mechanical shear for superior protection in hot conditions. AMSOIL 0W-50 Synthetic ATV/UTV Motor Oil’s all-season performance makes it ideal as a year-round oil in applications that recommend switching to a 10W-50 in hot weather, helping riders avoid time and money spent on maintenance

Confident Clutch Feel

AMSOIL 10W-40 Synthetic ATV/UTV Motor Oil’s superior friction-durability properties help minimize clutch slippage, fade and chatter, giving riders consistent clutch feel during takeoffs or when maneuvering around obstacles on the trail. It delivers confidence that vehicles will perform consistently in all types of riding conditions.

Wet-Clutch Compatible

AMSOIL Synthetic ATV/UTV Motor Oil contains no friction modifiers and promotes smooth shifting and positive clutch engagement. It controls heat and helps improve clutch life

Protects my Can Am engine.

My UTV works hard in the WV mountains and I depend on the superior protection from wear and tear with Amsoil products.

5W-50 UTV Oil

I use this oil in my Cub Cadet side-by-side. It does a good job of helping stop fuel dilution of the oil (b/c of fuel injection). It allows me have a more normal oil change interval because the oil level increases over the interval and this quality oil has helped remedy that issue. This oil even when contaminated with gasoline still comes out of the engine clean at oil changes.

Great for XC race Quads and Dirtbikes

We run this in our Yamaha YFZ450R GNCC and local race quads. We get better top end life and clutch life than with previous brands. We also run it in our KTM and Yamaha dirt-bikes with the same great results. I highly recommend Amsoil for your 4-stroke powersports needs.
