Diesel Fuels for Use at Very Low TemperaturesAt very low temperatures the fluidity of No. 2 diesel
fuel may become insufficient due to parraffin
separation. For this reason the vehicle comes equipped
with a fuel preheater. It permits a troublefree engine
operation to a temperature of approximately 14 °F (–
10 °C) when using No. 2 diesel fuel.
To avoid malfunctions, No. 2 diesel fuel of a lowered
cloud point is marketed during the cold season.
At temperatures below 14 °F (–10 °C) use winterized or
No. 1 diesel fuel only. If not available, a certain
quantity of kerosene or fuel flow improver may be
added. Mixing only to be done within the vehicle’s fuel
tank. Kerosene has to be filled in before the diesel fuel.
Engine power may drop according to the proportion of
kerosene. For this reason, keep percentage of kerosene
added to the minimum necessitated by the ambient
temperature.
The following information can be used as a reference,
if adding of kerosene becomes necessary. The mixing
ratios shown refer to the total mixture.Ambient temperature:
14 °F to –4 °F (–10 °C to –20 °C)
No. 2 Diesel Fuel: 70%
Kersosene: 30%
Ambient temperature:
below –4 °F to (–20 °C)
No. 2 Diesel Fuel: 50 %
Kersosene: 50 %
Even in extreme climatic conditions, the maximum
mixture ratio should not exeed 50 %.
Adding of kerosene to No. 1 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.
Damage or malfunctions resulting from poor fuel
quality or from blending specific fuel additives are not
covered by the Sprinter Warranty.Freightliner-all.book Pag e 171 Monday, December 1, 2003 2:54 PM
