Diesel
Fuel grade
Only refuel with ULTRA-LOW SULFUR DIESEL FUEL (ULSD, 15 ppm SULFUR MAXIMUM). Using other diesel fuels could result in increased wear and damage to the engine and/or exhaust system.
Never refuel with marine diesel or heating oil.
Do not mix these fuels with diesel fuels and do not use any special additives, as this may result in damage.
Use a filter when adding fuel from a fuel can. Otherwise, the fuel lines and/or the fuel injection system could be blocked by particles from the fuel can.
Usually, you will find information about the fuel grade on the pump. If you cannot find the label on the gasoline pump, ask the gas station staff.
You can find more information under “Fuel”, or by contacting an authorized Mercedes-Benz Service Center or visiting http://www.mbusa.com (USA only).
Low outside temperatures
Do not use gasoline to refuel vehicles with a diesel engine. Never mix diesel with gasoline or kerosene, as this may result in damage to the engine or fuel system.
Diesel fuel with improved cold flow properties is available during the winter months. Further information on fuel properties can be obtained from oil companies, e.g. at gas stations.
