For engine-oil service, 10W-40 is among the oil grades identified for this model. The oil application is 4-stroke, which is worth checking when selecting an oil made for powersports engines.
The available engine-oil capacity figure is 2.22 quarts. Follow the service procedure and check the final level rather than relying on the quantity alone. Among the synthetic oil choices returned for this application are 10W-40 Synthetic ATV/UTV Engine Oil, Formula 4-Stroke Power Sports Synthetic Motor Oil.
What does 10W-40 mean on an engine-oil label?
The number before W describes the oil’s cold-temperature viscosity classification, while the second number describes its viscosity at operating temperature. The grade does not, by itself, establish whether the oil meets all the requirements for an ATV engine.
