At The Filling Station - Alfa Romeo 159 Owner's Manual

AT THE FILLING
STATION
IMPORTANT Refuelling shall always
be performed with engine off. Failing to
observe this precaution could cause the
gauge to provide wrong indications.
Should this occur, to restore proper in-
dication just have next refuelling with
the engine off. Otherwise contact Alfa
Romeo Authorized Services.
PETROL ENGINES
Use only unleaded petrol. To prevent er-
rors, the diameter of the fuel tank filler
is too small to introduce a lead petrol
pump filler. Use petrol with a rated oc-
tane number (R.O.N.) not lower than
95.
IMPORTANT An inefficient catalyst
leads to harmful exhaust emissions, thus
contributing to air pollution.
IMPORTANT Never use leaded
petrol, even in small amount or in an
emergency, as this would damage the
catalyst beyond repair.
DIESEL ENGINES
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffins and could clog the diesel fu-
el filter.
In order to avoid these problems, dif-
ferent types of diesel are distributed ac-
cording to the season: summer type,
winter type arctic type (mountains/cold
areas).
If refuelling with diesel fuel not suitable
for the current temperature, mix diesel
fuel with TUTELA DIESEL ART ad-
ditive in the proportions stated on the
can, putting first the antifreeze in the
tank and then the diesel fuel.
If driving or parking the vehicle for a long
period in cold areas/mountains, refuel
with the diesel fuel available at local fill-
ing stations. In this situation you are al-
so recommended to have in the tank an
amount of fuel 50% higher than usable
capacity.
