Do you need to change the oil in supercharger everytime engine oil?

No, you do not need to change the oil in a supercharger every time you change the engine oil. Superchargers typically have their own dedicated oil reservoir and require less frequent oil changes than the engine itself. The recommended oil change interval for a supercharger will vary depending on the manufacturer and model, but it's usually significantly longer than the engine oil change interval (often measured in years or tens of thousands of miles rather than thousands). Always consult your supercharger's owner's manual for the correct maintenance schedule.
