Usage

Designed for the rigorous demands of powersports, PS-4 excels in a wide temperature range—from sub‑zero winter mornings to scorching summer trails. Whether you are tackling rocky back‑country paths, hauling heavy loads, or simply commuting on a daily basis, this oil maintains optimal viscosity, ensuring smooth lubrication during cold starts and stable film strength under high‑heat conditions. The kit is ideal for owners performing regular maintenance, as well as for service professionals seeking a reliable, brand‑matched oil change solution.

Why Choose Us

Polaris engineers the PS‑4 formula in‑house, meaning the oil is tuned to the exact tolerances and material specifications of Polaris engines. The full synthetic base provides superior thermal stability compared to conventional blends, while the proprietary additive package actively cleans existing deposits and prevents new ones from forming. Each batch undergoes rigorous testing for wear protection, sludge control, and corrosion resistance, delivering a product that meets or exceeds OEM performance criteria. Additionally, the inclusion of a matching filter ensures that contaminants are captured before they can circulate, extending engine life and reducing maintenance intervals.
