2020 Mercedes-Benz C-Class Engine Oil Type & Capacity

What oil does a 2020 Mercedes-Benz C-Class take?

Most Mercedes-Benz C-Class variants from around 2020 use a full-synthetic engine oil matching the manufacturer's API and ACEA specifications. The correct grade (typically 0W-20, 5W-30, or similar) depends on engine variant and climate region. Use the lookup tool below to confirm the correct grade, capacity and filter for your specific build.

Oil change interval

Mercedes-Benz typically recommends an oil and filter change every 10,000 km or 12 months, whichever comes first — though severe-duty conditions (stop-start city driving, towing, dusty environments) warrant shorter intervals around 7,500 km. Always check the service schedule in the 2020 Mercedes-Benz C-Class owner's manual for the authoritative figure.
