Fuel: Description and Operation







FUEL REQUIREMENTS - DIESEL ENGINE

NOTE: Marine diesel fuel, bio diesel fuel, heating oil or the like must not be used.

Do not blend diesel fuel with marine diesel fuel, bio diesel fuel or heating oil. The use of such non-approved fuels or blending diesel fuel may result in malfunction or cause engine damage. Damage or malfunctions resulting from poor fuel quality or from blending specific fuel additives are not covered by the Sprinter warranty.

WARNING: Under no circumstances should gasoline be mixed with diesel fuel. Due to the high pressure and high temperature in the injection system, there is a risk of fire and explosion. In addition, there is a risk of engine damage. Always follow basic safety rules when working with any combustible material.

Only use commercially available vehicular ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm SULFUR MAXIMUM). Information on diesel quality can normally be found on the fuel pump.
The exhaust after treatment device (DPF) will be seriously damaged if you use.
- LOW SULFUR HIGHWAY DIESEL FUEL (500 ppm SULFUR MAXIMUM)
- any other diesel fuel with a sulfur content of above 15 ppm
- any other diesel fuel with a bio diesel content of above 2 %
Commercially available vehicular ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL may contain up to 2 % bio diesel. This proportion will not have an effect on performance and wear.
For more information on diesel fuels contact your authorized Sprinter Dealer.

DIESEL FUELS FOR USE AT VERY LOW TEMPERATURE

Only use commercially available vehicular ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL (15 ppm SULFUR MAXIMUM).

To prevent malfunctions, diesel fuel with improved cold flow characteristics is offered in the winter months. Check with your fuel retailer.

At very low temperatures the fluidity of No. 2 diesel fuel may become insufficient due to paraffin separation. For this reason the vehicle comes equipped with a fuel preheater. It permits trouble-free engine operation to a temperature of approximately 14 °F (-10 °C).

At temperatures below 14 °F (-10 °C) a certain quantity of fuel flow improver may be added. These substances may only be mixed within the vehicle's fuel tank.

Engine power may drop according to the proportion of fuel flow improver. For this reason, keep the percentage of fuel flow improver to the minimum necessitated by the ambient temperature.
Do not fill the tank with gasoline.
Do not mix diesel fuel with gasoline or kerosene. The fuel system and engine will otherwise be damaged, which is not covered by the Sprinter warranty.

Adding kerosene to diesel fuel is not recommended even at low temperatures.

Do not blend other specific fuel additives with diesel fuel except for fuel flow improver. They only result in unnecessary cost, and may be harmful to the engine operation.
