B7 stands for diesel fuel with a maxi-
mum RME content of 7%.

Synthetic diesel fuels
Synthetic diesel fuels.
XTL stands for X - To - Liquid and is the
designation for synthetic diesel fuels.
Diesel fuels that are manufactured syn-
thetically are referred to as XTL fuels.
These synthetic diesel fuels include, for ex-
ample, GTL (Gas To Liquid), BTL (Biomass
To Liquid) and HVO (Hydrotreated Vegeta-
ble Oils), where natural gas or biomass is
used as the primary energy carrier.

NOTICE
Refuelling with fuels that do not comply
with the standards and tha
t are not ap-
proved can result in a reduction in perform-
ance and considerable damage to the en-
gine and fuel system.
·
Before refuelling, check whether the fuel
identification specified on the fuel pump
meets the vehicle’s requirements.
·
To avoid damage to the fuel system and
engine failure, always refuel only with
fuels in accordance with the specified
standard and identification.
Petrol
T
he petrol types dier in their research oc-
tane number (RON). The vehicle may be fil-
led with petrol that has a higher RON than
the engine requires. However, this does not
provide any advantage in terms of fuel
ec
onomy or engine output.
The fuel information label on the inside of
the tank flap may show several types of
petrol, e.g. 95/92/97/93 RON. The high-
lighted petrol grades, 95/92 in the exam-
ple, are the preferred petrol grades for the
vehicle. The other listed petrol grades may
only be filled if the highlighted ones are not
available. In this case, choose the petrol
grade with the higher RON, e.g. 97 instead
of 93 RON.
Fill vehicles with a petrol engine only with
unleaded petrol or petrol with a maximum
ethanol content of 10 % (E10) →

ties, performance and service life of the en-
gine. Refuel with fuel that already contains
suitable additives →

NOTICE
Errors during refuelling or unsuitable fuel
a
dditives may cause damage to the vehi-
cle.
·
Before refuelling, check whether the fuel
standard specified on the pump meets
the vehicle’s requirements.
·
Use only additives that have been ap-
proved by the manufacturer in the ap-
proved quantity.
·
Refuel only with petrol that has the
specified or a higher Research Octane
Number (RON). If, in an emergency, you
have to use petrol with an octane num-
ber lower than the recommended num-
ber, drive at medium engine speeds and
avoid high engine loading. Avoid high en-
gine speeds and heavy engine loads. Re-
fuel with petrol with the correct octane
number as soon as possible.
Diesel
A
lways refuel diesel with a low sulphur
content or with sulphur-free diesel in order
to avoid damage to the engine and particu-
late filter.
Fill vehicles with a diesel engine only with
diesel or diesel with a maximum RME fuel
content of 7 % →
