PS-4 Extreme Duty Advantage: Polaris PS-4 Extreme Duty is made specifically for Polaris ORV’s that operate in high heat conditions such as extreme ambient temps, slow speed high load or sustained high RPM conditions. PS-4 Extreme Duty protects vital engine components, controls the harmful effects of oil oxidation and delivers maximum performance needed to protect the hardest working ORVs.
Only Polaris lubricants are specially developed with our engines to handle the intense conditions and high-performance requirements demanded by Polaris ATV, Ranger, General and RZR riders worldwide.
Full Synthetic High Temp Formula: PS-4 Extreme Duty uses the ultimate full synthetic base oil to deliver maximum performance and the highest temp engine protection. PS-4 Extreme Duty engine oil was developed specifically for Polaris 4-cycle engines with a custom antiwear additive system to let riders confidently and safely push their machines to the limit. Off-road engines average over twice the RPMs of passenger cars and run at significantly higher engine temperatures.
Custom Additive System: The Polaris-engineered additive system was formulated to reduce engine component wear, prevent oxidation in extreme temperatures and prevent rust and corrosion by controlling moisture within the engine. Proprietary anti-wear agents offer engine wear protection and performance not found in aftermarket or automotive oils. PS-4 Extreme Duty is designed to resist shear or oil thinning longer than leading aftermarket powersport oils.
