Diesel fuels at low temperatures
At low outside temperatures, paraffin sepa-
ration may cause the flow properties of the
diesel fuel to be insufficient.
To prevent operating problems, diesel fuel
with improved flow properties is available in
the winter months.
Winter diesel fuels are reliable down to out-
side temperatures of −22
† in Germany and
other Central European countries. You can
normally use winter diesel fuel without prob-
lems at the outside temperatures expected in
the country where it is on sale.
Fuel additives
General notes
Fuel additives used to improve flow charac-
teristics are flow improvers.
Do not add flow improvers to winter diesel
fuel guaranteed to operate down to −22 †.
The
cold flow properties of the fuel may dete-
riorate as a consequence of the flow
improver.
If summer
diesel fuel or winter diesel fuel with
less resistance to low temperatures is in use,
add a quantity of flow improver, depending on
the outside temperatures.
Add the fuel additive to the diesel fuel in good
time, before paraffin separation causes the
diesel fuel's flow properties to be insufficient.
Malfunctions as a result of paraffin separation
can only be rectified by heating up the com-
plete fuel system.
The engine can be equipped with a heated
fuel prefilter with water separator. This also
improves the flow characteristics of the die-
sel fuel by approximately 8 †.
Flow improvers
The effectiveness of flow improvers cannot be
guaranteed with all fuels. Follow the manu-
facturer’s recommendations. Information
about approved flow improvers is available
