Diesel
Fuel system
Diesel engines are very sensitive to contamination. Only use diesel fuel
from a well-known oil company that fulfils the requirements for recom-
mended fuel grade as described on page 174. Never use diesel of
doubtful quality. The major oil companies can also offer a special diesel
fuel for winter use. This fuel is much thinner when the temperature is
low, which reduces the risk of waxing in the fuel system.
The risk of condensation building up in the tank is reduced if the tank is
kept well filled.
During filling you should check that the area around the filler pipe is
clean. If you do the refuelling from a tank of your own, you should filter
the fuel.
Avoid spilling onto the paintwork. Wash off any spills with detergent and
water.
Empty tank
No special procedures are required if the tank runs 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 water from fuel filter
The fuel filter removes condensation, which could otherwise affect engine
function, from the fuel. The fuel filter should be drained as specified in
the Service and Warranty Manuals, and when you suspect that the car has
been filled with contaminated fuel.
Important!
Diesel fuels not to be used:
special additives, Marine Diesel Fuel, fuel oil, RME (Rape Methyl
Ester), vegetable oil.
These fuels do not fulfil the requirements of Volvo’s recommendation
and generate increased wear and engine damage that is not covered by
the Volvo warranty.
