WARNING
Engine oil
Should prevailing use of the car be under
one of the following specially heavy condi-
tions:
– trailer or caravan towing
– dusty roads
– short distances (less than 7-8 km) re-
peated and with external temperatures be-
low zero.
– frequently idling engines or long distance
low speed driving (e.g. taxis or door-to-door
deliveries) or in case of a long term inac-
tivity.
Replace engine oil more frequently than
required on
SERVICE SCHEDULE
.WARNING
Fuel oil filter
The variety of the degree of purity of the
fuel oil in commerce may make it necessary
to change the fuel oil filter more frequently
than stated in the Scheduled Maintenance
Programme. If the engine is “sobbing” it
is a sign that the filter needs changing.WARNING
Air cleaner
Using the car on dusty roads, change the
air cleaner more frequently than stated in
the Scheduled Maintenance Programme.
For any doubts about the intervals be-
tween engine oil and air cleaner changes
in relation to how the car is used, contact
Alfa Romeo Authorized Services.

The engine oil level should be checked
when the car is standing on a level surface
a few minutes (about 5) after the engine
has been switched off.
Remove the dipstick (A), clean it, put it
back completely, remove it once again and
check that the level is between the MIN
and MAXmarks on the dipstick.
The interval between the MINand MAX
marks corresponds to approximately 1 liter
of oil.If the oil level is near or even below the
MIN, mark, add oil trough the filler neck
(B), until reaching the MAXmark. Never add oil with char-
acteristics (classification,
viscosity) which are differ-
ent from those of the oil already in
the circuit.fig. 7 - T.SPARK versions fig. 8 - 2.0 JTS version

Max. engine oil consumption is usually
400 grams every 1000 km.
During the initial period of use the engine
settles, therefore the engine oil consump-
tion can only be considered stabilised after
the first 5000 ÷ 6000 km.
WARNINGEngine oil consumption de-
pends on the way of driving and the condi-
tions of use of the car.

el surface and with the engine stopped and
cold.
To check the level, proceed as follows:
– turn the ignition key to MAR;
– disconnect the breather tube and re-
move the cap (A) checking that the level
corresponds with the MAXmark on the dip-
stick of the actual cap;
– if the level is below the MAXmark, top
up with oil until reaching the correct level;
– after screwing the cap back on, insert
the breather tube completely on the cap
spout and turn the ignition key to STOP.fig. 13
