Fuel c onsum ption
Fuel consump tion is determined und er
specific driv ing cond itions – see page 316.
Special equipment increases the weight of
the v ehicle. As a result, they can increase
fuel consump tion and reduce the specified
maximum speed.
For the first few thousand m iles, friction
between the eng ine and transmission
components is higher. This inc reases fuel
consump tion.
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 204, for
octane numbers see page 310). The
quality thereof has considerable effect on
the p erformance, running and serv ice life
of the engine. The additives mixed with the
fuel are extremely im portant. For this
rea son you must only refuel with high-
quality fuels containing additives.
Fuels with ethanol content greater than 5%
do not comply w ith DIN EN 228 a nd must
not b e used unless the v ehicle ha s b een
specifically develop ed a nd approved for
these fuels.
Fuel with too low an octane number can
cause p inking. N o liability can be accepted
for resulting dam age.
Petrol with a higher octane number can
always be used.
The ignition tim ing adjusts automatically
to the grade of fuel used (octane
numb er) – see pa ge 310.
Use of petrol w ith a n oc ta ne rating of 95
will ensure economica l driving.
For vehicles with Z20 LEH
1)
engine, use of
95 RON fuel reduces p erform ance a nd
torque.
Fuel for diesel engines
Diesel engines m ust be operated only on
comm ercially av ailable 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
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
mixed up with 5% Bio fuel (FAME) do not
differ from conventional diesel fuel and do
not influence the vehicle’s driveability.
Importa nt: Diesel fuel m ixed with 5% FAM E
acc ording to DIN 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 you 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.
