STARTING AND DRIVING

Petrol

Petrol is a form of motor fuel.
Only use petrol from well-known producers.
Never use fuel of dubious quality. The petrol must
fulfil the EN 228 standard.
•
95 RON can be used for normal driving.
•
98 RON is recommended for optimum per-
formance and minimum fuel consumption.
When driving in temperatures above +38 °C, fuel
with the highest possible octane rating is recom-
mended for optimum performance and fuel econ-
omy.
IMPORTANT
•
Use only unleaded petrol to avoid damag-
ing the catalytic converter.
•
Fuel containing metallic additives must
not be used.
•
Do not use any additives which have not
been recommended by Volvo.
414
Alcohols-ethanol
IMPORTANT
•
Fuel that contains up to
10 percent by volume ethanol is permit-
ted.
•
EN 228 E10 petrol (max
10 percent by volume ethanol) is
approved for use.
•
Ethanol higher than E10 (max.
10 percent by volume ethanol) is not per-
mitted, e.g. E85 is not permitted.

Diesel

Diesel is a form of motor fuel.
Only use diesel fuel from well-known producers.
Never use fuel of dubious quality. Diesel fuel
must fulfil the EN 590, SS 155435 or
JIS K 2204 standard. Diesel engines are sensi-
tive to contaminants in the fuel, such as exces-
sively high volumes of sulphur particles for exam-
ple.
At low temperatures (lower than 0 °C) a paraffin
precipitate may form in the diesel fuel, which may
lead to ignition problems. The fuel qualities that
are sold must be adapted for season and climate
zone, but for extreme weather conditions, old fuel
or moving between climate zones, paraffin precip-
itate may occur.
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.
