General instructions
Diesel fuel must comply with DIN EN 590.
Cetane number not less than 51.
Fuel RME (biodiesel fuel) according to DIN 51 606.
Diesel vehicles can be run on PME fuel (vegetable oil methylester).
If biodiesel is used, fill the tank with PME fuel only.
Note: There may be only a slight deterioration in the traction and dynamic qualities of the vehicle.
PME fuel consumption may be slightly higher.
Using fuel that does not meet the above standard may clog the fuel filter.
Biodiesel fuel is operable up to an outside air temperature of -10°С.
When the outside air temperature is below -10°C, it is recommended to fill the tank with diesel fuel.
Operation in winter conditions
When using summer diesel fuel at an outside air temperature below 0°C, engine malfunctions may occur, as the fuel becomes viscous due to paraffin precipitation.
Therefore, in Germany, during the cold season, winter diesel fuel is used, which, depending on its brand, ensures uninterrupted engine operation at temperatures down to -15°C or down to -22°C.
In countries with different climatic conditions, there are other grades of diesel fuel, which for the most part have different temperature limits for their use from the above.
The vehicle is equipped with a fuel filter heater. Due to this, fuels designed for use at temperatures down to -15°C can be used at temperatures down to approximately -24°C.
If, at an air temperature below -24°C, the fuel has become so thick that the engine does not start, it is enough to let the car stand for some time in a heated room.
Diesel fuel should not be mixed with various additives, gasoline and other additives that increase its fluidity.
