Fuels, refuelling

Fuel consumption
Fuel consumption is determined under
specific driving conditions – see page
3 256.
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 kilometres,
friction between the engine and
transmission components is higher. 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 3 254). Use of fuel
with too low an octane rating can reduce
engine power and torque and will slightly
increase 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).
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. Diesel fuels must not be diluted
with fuels for petrol engines.
The flow and filterability of diesel fuel are
temperature-dependent. When
temperatures are low, refuel with diesel fuel
with guaranteed winter properties.

Refuelling

Follow the operating and safety instruc-
tions of the filling station when refueling.
