Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page 313.
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
Commercially available high-quality fuels
are suitable (catalytic converter –
see page 203, octane numbers –
see pages 308, 309). Fuel quality has a
decisive influence on the power output,
running behaviour and service life of the
engine. The additives contained in the fuel
play an important role in this regard. 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 neck of vehicles that
operate on unleaded fuel.
The ignition timing adjusts automatically
to the grade of fuel used (octane
number) – see pages 308, 309.
Use of petrol with an octane rating of 95
will ensure economical driving.
For vehicles with Z20 LEH
1)
engine, use
of 95 RON fuel reduces performance
and torque.
