How often do you change the oil in as MB C300?

For a Mercedes-Benz C300, it's generally recommended to change the oil every 10,000 miles or once a year, whichever comes first, if using synthetic oil. However, if you frequently drive in severe conditions—such as extreme temperatures, stop-and-go traffic, or towing—you may need to change it more often. Always refer to the owner's manual for the most accurate maintenance schedule specific to your model year.
