5W-50 Synthetic ATV/UTV Engine Oil

AMSOIL Synthetic Engine Oil for ATVs and UTVs is specially formulated to deliver maximum performance for hard-working vehicles. Designed for both demanding off-road use and general riding, this oil gives riders confidence and helps protect engines when pushed to the limit. AMSOIL’s advanced synthetic technology reduces engine heat and wear during intense operation. It is Warranty Secure™, meaning it won’t void your ATV/UTV’s warranty. This oil is a cost-effective, high-performance solution recognized and accepted by original equipment manufacturers (OEMs).

Benefits

Engine Protection Under Heavy Loads
Many ATV/UTV owners modify their vehicles with accessories such as roofs, doors, skid plates, winches, plows, and other add-ons that increase weight. These modifications, combined with aggressive riding or challenging terrain, place extra demands on the engine. The heat generated under these conditions can quickly degrade conventional oils and lead to increased wear. AMSOIL’s full synthetic technology for ATV/UTV applications helps protect engines from heat and offers superior durability under stress.

All-Weather High Performance
AMSOIL 5W-50 Synthetic Engine Oil remains fluid even in sub-zero temperatures to ensure excellent cold-start protection. It also withstands high temperatures and extreme shear forces, making it a high-performance, all-season synthetic oil. It performs well year-round, eliminating the need to switch to a 10W-50 oil in summer—saving time and maintenance costs for riders.

Wet-Clutch Compatibility
AMSOIL ATV/UTV Synthetic Engine Oil contains no friction modifiers, allowing smoother gear shifts, reduced clutch heat, and extended clutch life. It is fully compatible with wet-clutch systems.

Proven in Competition
This oil has been tested in extreme race conditions by AMSOIL-sponsored professional riders in the AMSOIL GNCC Series. It is finely tuned to deliver superior wear protection and consistent clutch performance, even in the toughest racing environments.

Compatibility with Other Oils
