Polaris PS-4 is a full synthetic 5W-50 engine oil built for Polaris 4-cycle powersports engines: ATVs, Rangers, Generals and RZRs. Its selling point is a Polaris-specific additive package aimed at cold-start wear, oxidation at high temperatures and moisture-driven rust during storage. Off-road engines spin at roughly twice car RPMs and run hotter, so the 5W-50 grade and anti-wear chemistry are tuned for that duty rather than for passenger cars. Owners rate it highly and most treat it as the safe factory-spec choice over automotive or generic powersports oils.

Owners give it very high marks and mostly describe it as the oil their Polaris was designed for. Complaints are rare and tend to be about value rather than performance.
Polaris PS-4 is a full synthetic 5W-50 all-season engine oil made for Polaris 4-cycle powersports engines. It uses a powersports grade full synthetic base oil and a Polaris-engineered additive system. This size is a 1 gallon container.
The additive package is formulated to reduce wear on critical engine components, protect them on startup, and prevent oxidation in extreme temperatures. It also controls moisture inside the engine to help prevent rust and corrosion during intermittent use, periods of non-use or storage. The anti-wear agents and nonfriction modified formula are designed for the high RPMs and temperatures of off-road engines, which average over twice the RPMs of passenger cars.
The oil is developed for Polaris ATV, Ranger, General and RZR engines. Fitment is listed for many General, Ranger, ACE and snowmobile models.
