How much oil does a 2026 Mercedes-Benz GLS need?

• Always verify the precise capacity in the owner’s manual or let our technicians measure and fill to the factory-specified level during service.
• Proper fill level is important for oil pressure, lubrication and turbocharger protection—our certified technicians confirm level and condition before returning the vehicle to you.
