Winter fuel
At low temperatures, obstructions due to paraffin pre-
cipitations may generate in the fuel system, which can
cause engine anomalies. When the outside temperature
drops below
0 °C ( 32 °F ), it is necessary to use winter
fuel, which can be used up to a temperature of -15 °C
( 5 °F ) and which can be purchased in filling stations
since the beginning of the cold season. Often, fuel with
additives (Superdiesel) is available, and it can be used
approximately up to a temperature of
-20 °C ( -4 °F ).
• At temperatures below
-15 °C ( 5 °F ) or -20 °C ( -4 °F ),
it is necessary to mix it with oil. The necessary mix-
ing percentages can be obtained from the diagram re-
ported here to the side.
In case only summer fuel is available and temperature is
below
0 °C , fuel can be mixed with oil in the percentages
reported in the diagram anyway, in any case up to a max-
imum of
60 % .

Fuel storage
Prolonged storage of fuel can lead to the accumulation of
impurities and condensation in the fuel. Engine trouble
can often be traced to the presence of water in the fuel.
The storage tank must be placed outside and the temper-
ature of the fuel should be kept as low as possible. Drain
off water and impurities regularly.
