Polaris PS4 Oil Change Kit for RANGER and Sportsman - Full Synthetic

In this review the Polaris PS4 Oil Change Kit is evaluated for owners of specific RANGER, Sportsman, Scrambler, and ACE 500 models with 4-stroke engines who want a single kit to complete a service. The bottom line: it is a practical, OEM-focused kit that includes two quarts of the brand's PS-4 full synthetic 5W-50 oil plus an oil filter and drain washer, and its biggest selling point is that the lubricant is formulated specifically for Polaris powersports engines to help protect and extend engine life in a wide range of temperatures.

Key Features

• Full Synthetic Formula: The PS-4 5W-50 base oil delivers powersports-grade protection designed for high-performance four-cycle engines.
• Custom Additive System: Polaris additives reduce engine deposits and wear while helping control moisture to limit rust and corrosion.
• Wide Viscosity Range: The 5W-50 viscosity covers cold starts and hot running conditions, rated to perform from about -40F to 100F for seasonal versatility.
• Engine-Specific Design: PS-4 is formulated for Polaris engines to maintain peak performance under intense riding conditions.
• Complete Kit: Includes two quarts of PS-4 oil, one oil filter, and one drain plug washer so you can perform a single oil change without sourcing parts separately.

Who It's For

The kit is best for Polaris owners who ride RANGER, Sportsman, Scrambler, or ACE 500 models with a 4-stroke engine and want an OEM-grade oil change solution that matches factory recommendations. It suits owners who value a full synthetic oil tuned to powersports use and prefer buying a ready-to-use package that includes filter and washer.

Those who should look elsewhere include riders with non-Polaris-specific engines or machines that call for a different viscosity, and owners needing multiple oil changes per service interval (the kit contains two quarts and may not cover larger oil capacities). Also check fitment if your model year uses a different filter or washer size.

• Customers report good oil quality and straightforward installation for compatible models.

Cons
