Fuel c onsum ption
Fuel consump tion is determined und er
specific driv ing cond itions – see page 287.
Special equipment increases the weight of
the v ehicle. As a result, they can increase
fuel consump tion and reduce the specified
max imum speed.
For the first few thousand m iles /
kilometres, friction between the engine and
transm ission com ponents is higher. This
increases fuel consumption.
Fuel for petrol engines
Normal c om mercial high-quality fuels with
a m aximum ethanol content of 5% in
accordance with DIN EN 228 are suitable
(for catalytic converter see pag e 190, for
octane numbers - see pages 284, 285). The
quality thereof has considerable effect on
the p erformance, running and serv ice life
of the engine. The additives mix ed with the
fuel are extremely im portant. For this
rea son you must only refuel with high-
quality fuels containing additives.
Fuels with ethanol c ontent greater than 5%
do not comply with DIN EN 228 and must
not be used unless the vehicle has been
specifically dev eloped and app rov ed for
these fuels.
Fuel with too low an octane number can
cause pinking. Vauxhall cannot be held
lia ble for resulting dama ge.
Petrol with a higher octane number can
always be used.
The use of 91 octane fuel is not permitted
1 )
in v ehicles with the Z 22 YH
Vectra VXR.
The ignition tim ing adjusts automatically
to the grade of fuel used (octane
numb er) – see pa ges 284, 285.
Use of petrol w ith a n oc ta ne rating of 95
will ensure economica l driving.
Fuel with 95 RO N w ill result in less power
and torque with the Vectra VXR.
Fuel for di esel engines
Diesel engines must be operated only on
commerc ia lly available diesel fuel meeting
the specifications of DIN EN 590.
Since J anuary 2004, some oil companies
ha ve m ixed their diesel fuel with up to 5%
Bio fuel (FAME = Fatty Acid Methy l Esters)
lik e RM E (Rape-Oil Methyl Ester). This is in
accordance with the current DIN EN 590
and does not harm the fuel/injec tion
sy stem. The characteristic s of a diesel fuel
mixed up with 5% Bio fuel (FAME) do not
differ from conv entional d iesel fuel and do
not influence the vehicle's driveability.

engine or the Diesel fuels w ith improved low temp erature
properties are therefore a vailable on the
ma rk et during the winter months. Make
sure that y ou fill the tank with winter fuel
before the start of the cold weather
season.
Additives can be used with diesel fuels with
winter prop erties that are guaranteed by
the manufa cturer and when using diesel
fuel filters that are heated depending on
the outside temperature.
Diesel fuels must not be diluted with fuels
that are intended for petrol eng ines.
Fuel filler cap
When replacing the fuel filler cap, be sure
to use a genuine fuel filler cap for y our
model to ensure full functionality. Diesel-
eng ined vehicles have special fuel filler
cap s.
