Drivin g and Operation
Fuels with ethanol content greaterthan 5%
do not comply w ith DIN EN 228 a nd must
not b e used unless the vehicle ha s b een
specifically developed and approved for
these fuels.
Fuel for diesel engi nes
Fuel consumption
Diesel engines must be operated only on
commercially available diesel fuel meeting
the specifications of DIN EN 590.
Fuel consumption is determined under
specific driving conditions – see page 212.
Special equipment increases the weight of
the vehicle. As a result, they can increase
fuel consumption and reduce the specified
maximum speed.
Since January 2004, some oil companies
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
accordance with the current DIN EN 590
and does not harm 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.
Fuel with too low an octane number can
cause pinking. Vauxhall cannot be held
liable for resulting damage.
For the first few thousand miles /
kilometres,friction between the engine and
transmission components is higher. This
increases fuel consumption.
Petrol with a higher octane number can
always be used.
Do notuse 91 octane petrol in vehicles with
the Z 16 LET1) engine.
Fuel
The ignition timing is automatically
adjusted according to the grade of fuel
used (octane number) – see page 208.
Fuel for petrol engines
Important: Diesel fuelmixed with 5% FAM E
according to DIN EN 590 must not be
confused with 100% Bio Diesel, which is not
to be used in Vauxhall engines.
Normal commercial high-quality fuels with
a maximum ethanol content of 5% in
accordance with DIN EN 228 are suitable
(for catalytic converter see page 145, for
octane numbers see page 208). The
quality thereof has considerable effect on
the performance, running and service life
of the engine. The additives mixed with the
fuel are extremely important. For this
rea son you must only refuel with high-
quality fuels containing additives.
Use of petrol with an octane rating of 95
will ensure economical driving.
For vehicles with Z 16 LET1) engine, use of
95 RON fuel reduces performance and
torque.
The flow and filterability of diesel fuel are
temperature-dependent.
Dieselfuels with improvedlow temperature
properties 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.
Additives can be used with diesel fuels with
winter properties 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 engines.
