What can happen if an ATV engine is overfilled with oil?
Excess oil can be churned or aerated by moving parts in some engines, which may interfere with lubrication and cause leaks or other problems. Oil capacity is useful for planning a service, but the final level should be checked using the engine’s specified procedure.
Does using synthetic oil change the viscosity grade an ATV needs?
No. Synthetic describes how the oil is formulated; it is separate from the SAE viscosity grade. A synthetic oil still needs the appropriate grade and engine-application specifications.
