The engine-oil viscosity shown for this model is 10W-40. The available oil-product listings include 10W-40 Synthetic ATV/UTV Engine Oil, Formula 4-Stroke Power Sports Synthetic Motor Oil. For a service, choose oil that meets the engine’s actual application requirements, not just a product name.

Engine oils differ in additive packages and friction characteristics. Some powersports engines share oil with a wet clutch or transmission, so matching the manufacturer’s oil requirements matters in addition to viscosity. This listing does not by itself confirm the clutch design.
