08 Starting and driving

Fuel - petrol

Petrol is used as fuel.
Petrol must fulfil the EN 228 standard. Most
engines can be run with octane ratings of 95
and 98 RON. A lower octane rating such as
91 and 92 RON should only be used in
exceptional cases
•
95 RON can be used for normal driving.
•
98 RON is recommended for optimum
performance and minimum fuel consump-
tion.
When driving in temperatures above +38 °C,
fuel with the highest possible octane rating is
recommended for optimum performance and
fuel economy.
IMPORTANT
•
Use only unleaded petrol to avoid
damaging the catalytic converter.
•
Fuel that contains up to 10 volume-%
ethanol is permitted.
•
Fuel containing metallic additives must
not be used.
•
Do not use any additives which have
not been recommended by Volvo.

approved for use.
•
Ethanol higher than E10
(max 10 percent by volume ethanol) is not
permitted, e.g. E85.

Fuel - diesel

Diesel is used as fuel.
Only use diesel fuel from well-known produc-
ers. Never use fuel of dubious quality. Diesel
fuel must fulfil the EN 590 and/or SS 155435
standards. Diesel engines are sensitive to
contaminants in the fuel, such as excessively
high volumes of sulphur particles for exam-
ple.
At low temperatures (-6 °C to -40 °C), a par-
affin 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 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 deter-
gent and water.
