Polaris PS4 Oil Change Kit — PS-4 EXTREME 0W-50 Full Synthetic Oil Kit for RANGER/GENERAL/RZR with OEM Filter & Crush Washer

Polaris PS4 Oil Change Kit (2890057) is a complete maintenance pack containing 2.5 quarts of PS‑4 EXTREME 0W‑50 full synthetic oil, a dedicated oil filter, and a crush washer tailored for RANGER, GENERAL and RZR models.

Keep your Polaris off‑road vehicle running smoothly across wide temperature swings with an oil kit engineered specifically for powersports engines. The PS‑4 EXTREME formula blends PAO and ester base stocks with a Polaris‑designed additive package that reduces deposits, boosts wear protection, and resists oxidation and corrosion during intermittent use. This kit supplies the fluids and hardware you need for a single oil change so you can perform fast, correct service between trail runs or seasons.

How does PS‑4 EXTREME 0W‑50 protect engines in extreme temperatures?

The 0W‑50 viscosity rating gives a broad operating range so the oil flows at very low temperatures while maintaining film strength at high heat. The PAO and ester base oils resist breakdown, and the additive system prevents oxidation and viscosity loss under prolonged stress.

• Usable ambient range from about -45°F up to 130°F+
• PAO and Ester base oils for thermal stability
• Additives that reduce oxidation and deposit formation
• Maintains lubricating film at high rpm and load

What components are included and why do they matter?

This kit includes 2.5 quarts of Polaris PS‑4 EXTREME SAE 0W‑50 oil, one OEM‑spec oil filter, and a crush washer for a proper drain plug seal. Having the correct filter and washer helps ensure a clean change and prevents leaks after service.

• 2.5 quarts of full synthetic 0W‑50 — correct volume for many Polaris models
• OEM oil filter — designed to meet Polaris filtration and bypass standards
• Crush washer — ensures a leak‑free drain plug seal after reassembly
• Packaged for one complete oil change, ready to use

Will this kit improve engine longevity and maintenance intervals?

While maintenance schedules depend on use and conditions, a high‑quality full synthetic and proper filtration reduce wear and deposit accumulation, helping engines run cleaner between services. This kit supports standard oil change procedures and helps maintain designed engine performance.

• Custom additive system reduces internal deposits
• Moly and ZDDP components enhance wear protection in high‑stress areas
• Reduced rust/corrosion risk for intermittent or seasonal storage
• Supports manufacturers' recommended servicing when used as directed

How easy is it to use this kit during routine service?

The kit is arranged for a straightforward oil change: drain, replace filter and washer, refill to spec, and check levels. Packaging and components simplify one maintenance cycle, whether in a home garage or at a shop.

• Sized for a single oil change to minimize waste
• OEM‑matched filter fits Polaris RANGER, GENERAL and RZR applications
• Clear viscosity label simplifies selection for wide temperature ranges
• No need to source separate filter or crush washer

Who is this for: Riders and owners of Polaris RANGER, GENERAL, and RZR models who want a ready‑to‑use, OEM‑aligned oil change solution that covers extreme temperature operation and reduces wear. This kit is aimed at weekend trail riders, seasonal users, and professional technicians who prefer Polaris‑engineered fluids and parts for reliable on‑vehicle service.
