AMSOIL synthetic technology protects hot, high-revving engines against wear. AMSOIL Synthetic ATV/UTV Motor Oil is Warranty Secure™ and will not void your ATV or UTV warranty. It is a cost-effective, high-performance alternative to original equipment manufacturer (OEM) fluids.
Severe-Service Engine Protection
Many enthusiasts modify their ATVs or UTVs with roof and door panels, skid plates, a winch, a plow or 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 5W-50 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. Its 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.
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.
RACING IS RESEARCH™
AMSOIL Synthetic ATV/UTV Motor Oil underwent on-track testing in the ATVs and UTVs of AMSOIL-sponsored professional riders in the AMSOIL GNCC Series. It is fine-tuned for outstanding wear protection and consistent clutch feel.
