Fuel consumption
Optional equipment (e.g. wide tyres,
towing equipment) increases the
ke rbweigh t a nd, in som e ca se s, also the
permissible Gross Vehicle Weight.
This in turn increases fuel consum ption and
red uces the maxim um speed of the vehicle.
W hen the ve hicle is new, the re is increased
friction b etween the engine and
transm ission components la sting for
several thousand m iles / kilom etres. This
also increases fuel consumption.
Fue l for pe trol engi nes
Commercially av ailable high-quality fuels
are suitable (see pag e 210). Fuel quality
ha s a decis ive influ e nc e o n t h e po wer
output, driv eability and life of the engine.
The additives contained in the fuel play an
important role in this regard. You should
the refore use only high-q uality fuels
containing additives.
Petrol 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.

Use of petrol with an octane rating of 95
will ensure economica l driving
F u el for die s el engi nes
Diesel engines must be operated only on
comm ercially available diesel fuel meeting
the specifications of DIN EN 590.
Since Ja nuary 2004, some oil comp anies
have mixed their diesel fuel with up to 5%
Bio fuel (FAME = Fatty Acid Methyl Esters)
like RME (Rape-Oil Methyl Ester). This is in
accorda nce with the current DIN EN 590
and d oes not ha rm the fuel / injection
system. The characteristics of a diesel fuel
mixed up with 5% Bio fuel (FAME) do not
differ from conventional diesel fuel and do
not influence the vehicle’s driveability.
Important: Diesel fuel mixed with 5% FAME
acc ording to DI N EN 590 m ust not be
confused with 100% Bio Diesel, which is not
to be used in Vauxhall engines.
The flow and filterability of diesel fuel are
temperature-dependent.
Diesel fuels with improved low temperature
prope rtie s are therefore a vailable on the
market during the winter months. Make
sure that you fill the tank with winter fuel
before the start of the cold weather
season.
Additive s can be used with dies el fuels with
winter prop erties that are guaranteed by
the manufacturer 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.
