Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page 287.
Special equipment increases the weight of
the vehicle. As a result, they can increase
fuel consumption and reduce the specified
maximum speed.
For the first few thousand miles, friction
between the engine and transmission
components is higher. This increases fuel
consumption.
Fuel for petrol 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 193, for
octane numbers see pages 284, 285). 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
reason you must only refuel with high-
quality fuels containing additives.
Fuels with ethanol content greater than 5%
do not comply with DIN EN 228 and must
not be used unless the vehicle has been
specifically developed and approved for
these fuels.
Fuel with too low an octane number can
cause pinking. Vauxhall cannot be held
liable for resulting damage.
Petrol with a higher octane number can
always be used.
The use of 91 octane fuel is not permitted
in vehicles with the Z 22 YH
1)
engine or the
Vectra VXR.
Pump nozzles for leaded fuel cannot be
inserted into the filler neck of vehicles that
operate on unleaded fuel.
The ignition timing adjusts automatically
to the grade of fuel used (octane number)
– see pages 284, 285.
Use of petrol with an octane rating of 95
will ensure economical driving.
Fuel with 95 RON will result in less power
and torque with the Vectra VXR.
