Fuel System - Volvo V50 Owner's Manual

Diesel

Fuel system

Diesel engines are sensitive to contaminants.
Only use diesel from a well-known oil
company. Never fill up with diesel if the quality
is dubious. The large oil companies also
produce a special winter-grade diesel for
temperatures around freezing. This fuel is less
viscous at low temperatures and reduces the
risk of wax forming in the fuel system.
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
runs dry.
RME (Rape methyl ester)
A maximum of 5% RME may be mixed with
the diesel.
Important!
There is a risk of engine damage if the
RME concentration is greater than 5%.
Maintenance and service
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.
