110 Driving and Operation

Fuel, refuelling

Fuel consumption
Fuel consumption is determined under
specific driving conditions 3 172.
Special equipment increases the weight of
the vehicle. As a result, they can increase
fuel consumption and reduce the specified
maximum speed.
There is increased friction between engine
and transmission parts during the first
600 miles (1000 kilometres). This increases
fuel consumption.
Fuel for petrol engines
Only use unleaded fuel that complies
with DIN EN 228.
Fuels with ethanol content greater than 5%
may only be used if the vehicle has been
specifically developed and approved for
these fuels.
Use fuel with the recommended octane
rating (value in bold 3 170). Use of fuel
with too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption.
Caution
Use of fuel with too low an octane rating
could lead to uncontrolled combustion
and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies with
DIN EN 590. The fuel must have low
sulphur content (maximum 50 ppm).
Since January 2004, some oil companies
have mixed their diesel fuel with upto 5%
Bio fuel (FAME = Fatty Acid Methyl Esters)
like RME (Rape-Oil Methyl Ester). This is in
accordance with the current DIN EN 590
and does not harm the fuel/injection
system. The characteristics of a diesel fuel
mixed up with 5% Bio fuel (FAME) do not
differ from conventional diesel fuel and do
not influence the vehicle's driveability.
Important: Diesel fuel mixed with 5% FAME
according to DIN EN 590 must not be
confused with 100% Bio Diesel, which is not
to be used in Vauxhall engines.
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.
Diesel fuels must not be diluted with fuels
that are intended for petrol engines.
