AMSOIL 5W-50 Synthetic ATV/UTV Engine Oil
Product Details
AMSOIL Synthetic ATV/UTV Motor Oil is formulated to deliver upgraded performance for hard-working and performance ATVs and UTVs. Its outstanding severe-service formulation allows riders to confidently and safely push their machines to the limit, whether tackling tough chores around their property or riding aggressively on the trail.
Product Description
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.

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.

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.

Premium, Purpose-Built Alternative
AMSOIL 5W-50 Synthetic ATV/UTV Motor Oil is formulated specifically by AMSOIL for use in Polaris* Ranger*, RZR* and Sportsman* UTVs and ATVs. It offers a cost-effective, high-performance alternative to OEM-branded fluids.

APPLICATIONS
Use AMSOIL 5W-50 Synthetic ATV/UTV Motor Oil in ATVs and UTVs that require a 5W-50 motor oil, including the Polaris Ranger, Polaris RZR and Polaris Sportsman. AMSOIL recommends 5W-50 Synthetic ATV/UTV Motor Oil in place of Polaris PS-4 and PS-4 Extreme Duty. *

SERVICE LIFE

COMPATIBILITY
AMSOIL Synthetic ATV/UTV Motor Oil is compatible with other synthetic and conventional motor oils. Adding other oils, however, will shorten the life expectancy of AMSOIL motor oils and reduce their performance benfits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL Synthetic ATV/UTV Motor Oil.
