What protection and performance does PS-4 5W-50 deliver?

PS-4 is a powersports-focused full synthetic oil formulated with a custom additive stack to control deposits, limit component wear, and resist oxidation in extreme temperatures. Its 5W-50 viscosity range provides cold-start flow and high-temperature film strength, helping maintain consistent lubrication across wide operating conditions.

• Full synthetic base oils for stable viscosity and shear resistance.
• Custom additives reduce deposits and protect critical parts.
• Wide temperature range (-40°F to 100°F) suitable for varied climates.
• Helps control moisture to reduce rust and corrosion risk.

What do I get in the box and why it matters?

The kit contains 2 quarts of Polaris PS-4 SAE 5W-50 full synthetic oil, one genuine Polaris oil filter, and a drain plug washer. Having the correct quantity of oil and the matching OEM filter ensures accurate oil level fill and proper filtration performance right after the service.

• 2 x 1-quart bottles of PS-4 5W-50 full synthetic oil for exact fill requirements.
• One OEM Polaris oil filter engineered for fit and filtration efficiency.
• New drain plug washer to prevent leaks and ensure proper sealing.
• Everything needed for a single oil change, reducing parts compatibility issues.

How do I install the oil and filter safely?

Perform oil changes on a warm, level engine following Polaris maintenance intervals and torque specs. Drain the warmed oil, replace the drain plug washer, install the new OEM filter lubricated with a light coat of oil on the gasket, then refill with the two quarts and check the level per the owner’s manual.

• Warm engine briefly to thin old oil for complete drain.
• Use the included washer and torque drain plug to factory specs.
• Lubricate filter gasket and hand-tighten to the specified torque.
• Refill and verify oil level on a level surface using the dipstick/inspection method.
