Polaris PS-4 Full Synthetic 5W-50 All-Season Engine Oil, 4-Stroke Engines, 2876245, 1 Gallon

PS-4 Advantage: Polaris PS-4 is made specifically for Polaris powersports engines to maintain peak performance longer than automotive and other aftermarket 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 a superior powersports grade full synthetic base oil to deliver better performance and engine protection. PS-4 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 typically run at significantly higher engine temperatures.

Custom Additive System: The Polaris-engineered additive package was formulated to reduce critical engine component wear, prevent oxidation in extreme temperatures and prevent rust and corrosion by controlling moisture within the engine that can form during intermittent use, periods of non-use or storage. The anti-wear agents and nonfriction modified full synthetic formula offers engine wear protection and performance not found in other aftermarket or automotive oils.
