Fuel consumption,
fuel, refuelling
Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page 221.
Fitting special equipment will increase the
weight of the vehicle. This in turn increases
fuel consumption and reduces the
specified maximum speed of the vehicle.
There is increased friction between engine
and transmission parts during the first
600 miles (1000 kilometres) . This increases
fuel consumption.

Fuel for petrol engines

Commercially available high-quality
fuels are suitable (catalytic converter –
see page 134, octane numbers –
see pages 218, 219). 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 is automatically
adjusted according to the grade of
fuel used (octane number) –
see pages 218, 219.
Use of petrol with an octane rating of 95
will ensure economical driving.

Fuel for diesel engines

Diesel engines must be operated only on
commercially available diesel fuel meeting
the specifications of DIN EN 590. Do not
use marine diesel oils, heating oils or
entirely or partially plant-based diesel
fuels, such as rape seed oil or bio diesel,
Aquazole and similar diesel-water
emulsions.
The flow and filterability of diesel fuel are
temperature-dependent.
Diesel fuels with improved low-
temperature properties are therefore
available 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.
