IMPORTANT
Mixtures of various fuel types or use of
fuels which are not recommended will
invalidate Volvo's guarantees and any sup-
plementary service agreements; this is
applicable to all engines.
NOTE
Extreme weather conditions, driving with a
trailer or driving at high altitudes in combi-
nation with fuel grade are factors that
could affect the car's performance.

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. Only in exceptional cases
should 91 RON be used.
•
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.
•
Do not use any additives which have
not been recommended by Volvo.

Fuel - diesel

Diesel is used as fuel.
Only use diesel fuel from well-known produc-
ers. Never use diesel of dubious quality. Die-
sel should fulfil the EN 590 or JIS K2204
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.
IMPORTANT
Only ever use fuel that fulfils the European
diesel standard.
The sulphur content must be a maximum
of 50 ppm.
