What kind of engine oil should be used for CFMOTO SR?

[StSpencer]

CFMOTO SR should use semi-synthetic engine oil. Smell of engine oil: Qualified engine oil has no special smell, with a slight fragrance, and the gasoline performance is relatively mild. If there is a pungent smell, especially a strong fuel smell, it is likely to be recycled engine oil. Method for observing engine oil: Check through oil drops. Drop a drop of oil from the oil pan onto white paper and observe the oil drop. If the black spot in the center of the oil drop is large, dark brown, uniform, and without particles, and the surrounding yellow infiltration is small, it indicates that the engine oil has deteriorated and should be replaced. If the black spot in the center is small and light in color, and the surrounding yellow infiltration trace is large, it indicates that the engine oil can still be used.
