Fuels, refuelling

Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page 272.
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 fuel
with a maximum ethanol content of 5% as
per DIN EN 228 (catalytic converter –
see page 161, octane numbers – see
page 268). Fuel quality has a decisive
influence on 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.
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
use of such.
Fuel with too low an octane number can
cause pinking. Vauxhall does not accept
liability for resulting damage.
Petrol with a higher octane number can
always be used.
The ignition timing is automatically
adjusted according to the grade of fuel
used (octane number) – see page 268.
Use of petrol with an octane rating of 95
will ensure economical driving.

For vehicles with Z 16 LER
95 RON fuel reduces performance and
torque.
