The Polaris PS4 Oil Change Kit supplies two quarts of PS‑4 5W‑50 full synthetic engine oil, a OEM oil filter, and a drain plug washer sized for select RZR models to complete a proper oil change.

Keep your Polaris RZR running dependably across wide temperature ranges with a kit engineered for powersports engines. This complete service set pairs Polaris’s PS‑4 full synthetic 5W‑50 oil—formulated specifically for their high‑performance machines—with a matching oil filter and a new crush washer so you can change the oil quickly and correctly. The oil’s additive package targets deposit control, corrosion prevention, and wear reduction to help preserve engine components during spirited riding or trail use.

What makes PS‑4 5W‑50 full synthetic oil different for RZR engines?

PS‑4 is a powersports‑grade synthetic blend tailored to the demands of Polaris engines, offering a wide viscosity range for dependable cold starts and high‑temperature protection. The custom additive system reduces deposits and helps control internal moisture and oxidation under severe operating conditions.

• Full synthetic base for consistent film strength and shear resistance.
• Custom additives to limit engine deposits and wear.
• Operational range from -40°F to 100°F for varied climates.

How does this kit simplify routine maintenance?

The kit brings together the exact oil type, the correct replacement filter, and a fresh drain plug washer so you don’t need to source individual parts. That reduces downtime and ensures you use components matched to Polaris specifications for compatibility and fit.

• Includes 2 quarts of PS‑4 SAE 5W‑50 oil sized for many RZR change intervals.
• OEM‑grade oil filter designed to trap contaminants effectively.
• New drain plug washer prevents leaks after reinstallation.

Will PS‑4 5W‑50 protect my engine under heavy use?

While no oil can prevent every failure, PS‑4 emphasizes wear protection, oxidation resistance, and deposit control—attributes important for engines pushed hard or exposed to dusty, wet, or hot conditions. The viscosity range helps the oil stay effective from cold starts to high‑load operation.

• Viscosity stability helps maintain oil pressure during high RPMs.
• Additives guard against rust and corrosion by managing moisture.
• Designed specifically to complement Polaris engine tolerances and performance needs.

How should I use this kit for the best results?

Perform oil changes according to your RZR owner’s manual and local riding conditions. Warm the engine briefly for easier draining, replace the filter and crush washer, then refill to the specified capacity and run the engine to check for leaks and proper oil pressure.

• Warm engine for a few minutes, then drain oil completely.
• Install the included Polaris oil filter hand‑tight plus specified torque if listed.
• Replace the drain plug washer with the included washer to ensure a reliable seal.

Who this is for: This oil change kit is intended for Polaris RZR owners and independent mechanics who want a factory‑matched maintenance solution—ideal for riders who perform regular service at home or fleets needing consistent, OEM‑spec consumables. It’s particularly useful for those who ride across seasonal temperatures and demand durable lubrication under varied trail and performance conditions.
