Fuel consumption and emissions of
carbon dioxide
Official fuel consumption figures are based
on a standard driving cycle in accordance
with EU Directive 80/1268 comb. Fuel con-
sumption figures may change if the car is
equipped with extra equipment that affects
the car’s weight. The manner in which the car
is driven, and other non-technical factors can
also affect fuel consumption. Consumption is
higher and power output lower for fuel with
an octane rating of 91 RON.
Petrol
Most engines can be run with octane ratings
of 91, 95 and 98 RON.
•91 RON must not be used for 4-cylinder
engines and should only be used in ex
-
ceptional cases with other engines.
•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 ºC,
fuel with the highest possible octane rating is
recommended for optimum performance and
fuel economy.
Petrol – Norm EN 228.
Diesel
The diesel engine’s fuel system is sensitive to
contaminants, see page 173.
IMPORTANT
Use only unleaded petrol to avoid damag-
ing the catalytic converter. In order for the
Volvo warranty to apply, never mix alcohol
with petrol, the fuel system could be dam-
aged.
