Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page 237.
Spe cial equipm ent increases the weight of
the vehicle. As a result, they can increase
fuel consumption and reduce the specified
maximum speed .
There is increased friction b etween eng ine
and transmission parts during the first
600 miles (1000 kilometres). This increases
fuel consumption.
Fuel for petrol engines
Com mercially available high-quality
fuels are suitable (catalytic conv erter –
see page 145, oc ta ne numbers – see
pag es 234, 235). Fuel quality has a d ecisive
influence on the power output, running
behaviour and service life of the engine.
The additives conta ined in the fuel play an
important role in this reg ard. You should
therefore only use high-quality fuels
containing additives.
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 .
Pump nozzles for leaded fuel cannot be
inserted into the filler nec k of vehicles tha t
ope rate on unlead ed fuel.
The ignition timing adjusts autom atic ally
to the grade of fuel used (octane number)
– see pages 234, 235.
Use of petrol with an octane rating of 95
will ensure economical driv ing.
