Compatibility indications for fuel:
1 For petrol with maximum 5% ethanol by vol‐
ume
2 For petrol with maximum 10% ethanol by vol‐
ume
The compatibility indications for fuel on the vehi‐
cle according to the European standard EN
16942 can be found on the information label in
the fuel filler flap or on the fuel dispenser or
pump nozzle suitable for your vehicle throughout
Europe.
If the available fuel is not sufficiently low in sul‐
phur, this can produce unpleasant odours.
The recommended octane number can be found
on the information label on the fuel filler flap
(
/
page 178).
If the recommended fuel is not available, you
may also temporarily use regular unleaded petrol
with an octane number of at least 91 RON.
This may reduce engine output and increase fuel
consumption.
Never refuel using petrol with an even lower
RON.
Further information on fuel can be obtained at a
filling station or a qualified specialist workshop.
Information on additives in petrol (vehicles
with petrol engine)
Observe the notes on operating fluids
(

page 461).
* NOTE Damage from use of unsuitable
additives
Even small amounts of the wrong additive
may lead to malfunctions occurring.
#
Only add cleaning additives recommen‐
ded by Mercedes-Benz to the fuel.
Mercedes-Benz recommends that you use
brand-name fuels with additives.
In some countries, the fuel available may not
have sufficient additives. Deposits could build up
in the fuel injection system as a result. In this
case, in consultation with a Mercedes-Benz
service centre, mix the fuel with the cleaning
additive recommended by Mercedes-Benz.
Observe the notes and mixing ratios indicated
on the tank.
