Diesel
Fuel system
Diesel engines are sensitive to contaminants.
Only use diesel fuel from a well-known oil
company that fulfils the requirements for
recommended fuel grade as described on
page 230. Never use diesel of dubious
quality. Special diesel fuel designed for low
temperatures around freezing point is
available from the major oil companies. This
fuel is less viscous at low temperatures and
reduces the risk of wax building up in the fuel
system.
The risk of condensation building up in the
tank is reduced if the tank is kept well filled.
Make sure that the area around the filler pipe
is clean when refuelling.
Avoid spilling onto the paintwork. Wash off
any spills 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), vegetable
oil.
These fuels do not fulfil the requirements
in accordance with Volvo recommenda-
tions and generate increased wear and
engine damage that is not covered by the
Volvo warranty.
