DIESEL ENGINES
The car must be refu-
elled only with fuel oil
for motor vehicles, in
conformity with European speci-
fication EN590. The use of other
products or mixtures may dam-
age the engine irreparably re-
sulting in invalidation of the
warranty for the damage caused.
If another type of fuel is acciden-
tally added to the fuel tank do
not start the engine. Drain the
tank. If the engine has been run
even for an extremely brief peri-
od the supply circuit must be
drained together with the tank.
If these precautions are not observed
the engine will suffer serious damage.
Fill the fuel tank before it is completely
empty in order to prevent air from getting
into the circuit.
During cold weather (external tempera-
ture below –10°C) the additive DIESEL
MIX should be used especially if the ve-
hicle is lying inactive for long periods.
This product should be mixed with the
diesel fuel in the quantities specified on
the bottle.
