Diesel
Diesel must meet the EN 590 or JIS K2204
standards.
IMPORTANT
Only ever use fuel that fulfils the European
diesel standard.
IMPORTANT
Diesel type fuels which must not be used:
special additives, Marine Diesel Fuel, fuel
oil, RME
1
(Rape Methyl Ester) and vegetable
oil. These fuels do not fulfil the requirements
in accordance with Volvo recommendations
and generate increased wear and engine
damage that is not covered by the Volvo
warranty.
Diesel engines are sensitive to contaminants,
such as excessively high volumes of sulphur
particles for example. Only use diesel fuel from
well-known producers. Never use diesel of
dubious quality.
At low temperatures (-40 °C to -6 °C), a paraffin
precipitate may form in the diesel fuel, which
may lead to ignition problems. Special diesel
fuel designed for low temperatures around
freezing point is available from the major oil
companies. This fuel is less viscous at low tem-
peratures and reduces the risk of paraffin pre-
cipitate.
IMPORTANT
Use special winter grade fuel during cold
months.
The risk of condensation in the fuel tank is
reduced if the tank is kept well filled. When
refuelling, check that the area around the fuel
filler pipe is clean. Avoid spilling fuel onto the
paintwork. Wash off any spillage with deter-
gent and water.
IMPORTANT
The sulphur content must be a maximum of
50 ppm.
Empty tank
The design of the fuel system in a diesel engine
means that if the vehicle runs out of fuel, the
tank may need to be vented in the workshop in
order to restart the engine after fuelling.
Once the engine has stopped due to fuel star-
vation, the fuel system needs a few moments
to carry out a check. Do this before starting the
engine, once the fuel tank has been filled with
diesel:
1. Insert the remote control key in the ignition
switch and turn to key position
II (see
page 150).
2. Wait approx. 1 minute.
3. To start the engine: Depress the brake and/
or clutch pedal, and turn the remote control
key to start position
III .
Draining condensation from the fuel filter
The fuel filter separates condensation from the
fuel. Condensation can disrupt engine opera-
tion.
The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet
or if you suspect that the car has been filled
with contaminated fuel.
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.
Diesel particle filter (DPF)
Diesel cars may be equipped with a particle fil-
ter, which results in more efficient emission
control. The particles in the exhaust gases are
collected in the filter during normal driving. So-
1 Diesel fuel may contain a certain amount of RME, but further amounts must not be added.
