PS-4 Advantage: Polaris PS-4 is made specifically for Polaris powersports engines to maintain peak performance longer than automotive and other powersports oils. Our Polaris Proprietary Additive System is formulated using the latest lubricant technology to protect vital engine components on startup, control moisture and deliver maximum engine protection for Polaris off-road vehicles. 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 Formula: PS-4 uses an excellent powersports-grade full synthetic base oil to deliver outstanding performance and engine protection. PS-4 engine oil was developed specifically for Polaris 4-cycle engines with a custom anti-wear 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 typically run at significantly higher engine temperatures.

New Custom Clean Engine Additive System: New Polaris-Exclusive Clean Engine Additive System was formulated to reduce engine deposits to help maintain peak power and performance. Tested against other products, it was proven to keep the engine at least 50% cleaner than all other tested oils. The custom additive system also prevents oxidation in extreme temperatures and prevents rust and corrosion that can form during intermittent use.
