Fuels, refu elling
Fuel c onsum ption
Fuel consump tion is determined und er
specific driv ing cond itions – see page 188.
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.
There is increased friction betw een engine
and transmission parts during the first
600 miles (1000 kilometres). This increases
fuel consum ption.
Fuel for petrol engi nes
Commercially av ailable high-quality fuel
with a max imum ethanol content of 5% as
per DIN EN 228 (cataly tic converter - see
page 115, oc ta ne numbers - see pa ge 186).
Fuel quality has a decisiv e influence on
power output, running behaviour and
service life of the engine. The additives
contained in the fuel play an important role
in this reg ard. Y ou should therefore only
use high-quality fuels conta ining additives.
Fuels with ethanol content greater than 5%
do not comply w ith DI N EN 228 a nd must
not b e used unless the v ehicle ha s b een
specifically develop ed a nd approved for
use of such.
Fuel with too low an octane number can
cause pinking. Vauxhall does not ac cept
lia bility for resulting damage.
Petrol with a higher octane number can
always be used.
The ignition tim ing is a utoma tica lly
adjusted according to the grade of fuel
used (octane number) – see page 186.
Use of petrol w ith a n oc ta ne rating of 95
will ensure economica l driving.
Driving an d Operation
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 upto 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.
