Diesel fuels at low temperatures
At low outside temperatures paraffin sepa-
ration may reduce the diesel fuel's free-
flowing properties.
To prevent operating problems, use diesel
fuel with improved flow properties in the
winter months.
In Germany, winter-grade diesel fuels are
sold which remain reliable in operation
down to approximately –20 °C. Winter-
grade diesel fuel can normally be used
without risk of malfunctioning at the out-
side temperatures expected in the country
where it is on sale.
Fuel additives
If summer-grade diesel fuel or winter-
grade fuel with less resistance to low tem-
peratures is in use, add a quantity of flow
improver or kerosene, depending on the
outside temperatures.
Add the additives to the diesel fuel at the
appropriate time, before paraffin separa-
tion reduces the diesel's flow properties.
Malfunctions resulting from paraffin sepa-
ration can only be removed by heating the
entire fuel system, e.g. by stopping the en-
gine in a heated area.
The vehicle is equipped with a fuel preheat-
ing system. This improves the flow proper-
ties of the diesel fuel by approximately
8 °C.
i
Do not use additives in winter diesel fu-
els. The fuel's flow properties could be
impaired by any such fuel additive.
Risk of fire and explosion
G
Adding petrol lowers the flash point of the
diesel fuel. This adds to the risk of handling
this fuel mixture.
Do not add petrol to diesel fuel.
