Fuel c onsum ption
O ptional equipment (e.g. wide tyres,
towing equipm ent) increases the
kerbweight a nd, in som e ca ses, also the
permissible Gross Vehicle Weight.
This in turn increases fuel consum ption and
red uces the max im um speed of the vehicle.
When the vehicle is new, there is increased
friction b etween the engine and
transm ission com ponents la sting for
several thousand m iles / kilom etres. This
also increases fuel consum ption.
Fuel for petrol engi nes
Commercially av ailable high-quality fuels
are suitable (see pag e 212). Fuel quality
ha s a decisive influenc e on the power
output, d riv eability and life of the engine.
The additives contained in the fuel play an
important role in this regard. You should
therefore use only high-q uality fuels
containing add itiv es.
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.
A dispensing p um p for leaded fuel c annot
be inserted in the fuel tank of a vehic le tha t
must b e operated on unlea ded fuel only .
Use of petrol w ith a n oc ta ne rating of 95
will ensure economica l driving
Fuel for diesel engi nes
Diesel engines m ust be operated only on
comm ercially av ailable diesel fuel meeting
the specifications of DIN EN 590.
S ince Ja nuary 2004, some oil comp anies
have mix ed their diesel fuel with up to 5%
Bio fuel (FAME = Fatty Acid Methyl Esters)
like RME (Rape-Oil Methyl Ester). This is in
acc orda nce with the current DIN EN 590
and d oes not ha rm the fuel / injection
system. The characteristics of a diesel fuel
mix ed up with 5% Bio fuel (FAME) do not
differ from conventional diesel fuel and do
not influence the vehicle's driveability.
I mporta nt: Diesel fuel m ixed with 5% FAM E
acc ording to DI N EN 590 m ust not be
confused with 100% Bio Diesel, which is not
to be used in Vauxhall eng ines.
The flow and filterability of diesel fuel a re
temperature-dependent.
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.
