Diesel Fuels for Use at Very Low Temperatures
At 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.
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.
