Polaris PS4 Oil Change Kit 5W-50 Full Synthetic - Complete Service Kit

In this review of the Polaris PS4 Oil Change Kit the bottom line is simple: this kit is aimed at owners of specific Polaris RANGER, GENERAL, RZR and ACE 900 XC models who want a straightforward, manufacturer-matched oil service in one box. The reviewer found the kit delivers the expected protection because it includes 2.5 quarts of PS-4 full synthetic 5W-50 oil and the correct oil filter and drain washer, which makes routine maintenance faster and keeps the engine running with a lubricant formulated for Polaris powersports engines.

Key Features

• Full synthetic formula: PS-4 5W-50 uses a powersports-grade full synthetic base oil to deliver higher performance and improved engine protection compared with conventional oils.
• Custom additive system: Polaris additive chemistry is designed to reduce deposits and wear on critical engine components for longer engine life.
• Wide temperature range: The 5W-50 viscosity covers cold starts and high ambient conditions, protecting engines from -40F up to 100F.
• Engine-specific advantage: PS-4 is formulated for Polaris powersports engines to help maintain peak performance under intense conditions.
• Complete kit contents: Includes 2.5 quarts of oil, one oil filter and one drain plug washer so owners have everything needed for a single oil change.

Who It's For

This kit suits owners of the listed Polaris UTV and SxS models who prefer OEM-matched fluids and want a quick, reliable oil change with minimal parts hunting. It is especially useful for riders who operate in varied climates and need a single oil that handles cold starts and hot-weather running.

Customers who perform frequent heavy-duty service or need larger service packs should look elsewhere for multi-change kits or bulk oil purchases, and those with models not listed should verify compatibility before buying. This is not intended for non-Polaris engines unless specifications match exactly.

Pros & Cons

Pros

• Packaged as a single service kit so users receive the right oil quantity plus filter and washer in one purchase.
• Full synthetic 5W-50 formulation provides strong protection across a wide temperature range.
• Polaris custom additive system helps reduce deposits and corrosion risk, supporting engine longevity.
• Customers report it is easy to use and correctly fills the motor for the covered models.

Cons

• The kit covers only one oil change amount; owners needing multiple services will need to purchase additional kits or bulk oil.
• Some users have mixed opinions about the included oil filter, so those wanting an upgraded filter option may prefer to swap it.
