Gasoline
Fuel grade
You should only refuel with unleaded premium-grade gasoline as this avoids damaging the catalytic converter.
If engine running problems are apparent, have the cause checked immediately and repaired. Excess unburned fuel can otherwise enter the catalytic converter, leading to overheating and possibly causing a fire.
Use a filter when refueling from a fuel can.
Otherwise, the fuel lines and/or injection system could be blocked by particles from the fuel can.
Only refuel with premium-grade unleaded gasoline with a specified minimum octane number of 91 (average value of 96 RON/ 86 MON).
You will usually find information about the fuel grade on the pump. If you cannot find the label on the pump, ask the staff for assistance.
You can find more information under "Fuel", or by contacting an authorized Mercedes-Benz Service Center or visiting http://www.mbusa.com (USA only).
