Maintenance and service
Diesel
Fuel system
Diesel must fulfil the EN 590 or JIS K2204
standards. Diesel engines are sensitive to
contaminants, such as high volumes of
sulphur particles for example. Only use diesel
fuel from a 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 can lead to ignition problems.
Special diesel fuel designed for low tempera-
tures around freezing point is available from
the major oil companies. This fuel is less
viscous at low temperatures and reduces the
risk of paraffin precipitate
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
detergent and water.
Empty tank
No special procedures are required if the
tank is run dry. The fuel system is bled
automatically if the ignition switch is kept in
position
II for approx. 60 seconds before the
start attempt.
Draining condensation from the
fuel filter
The fuel filter separates condensation from
the fuel. Condensation can disrupt engine
operation.
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!
Diesel type fuels which must not be used:
special additives, Marine Diesel Fuel, fuel
oil, RME (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.
IMPORTANT!
For model year 2006 or later the sulphur
content must be a maximum of 50 ppm.
IMPORTANT!
Certain special additives remove the
water separation in the fuel filter.
