Vehicles with petrol engine M256: when using
95 RON, there may be slight limitations in per-
formance that have no further consequences.
All models: if you wish to achieve maximum
engine output, refuel using only super unleaded
petrol with an octane number of at least 98 RON.
Alternatively, you can also refuel using premium-
grade petrol with an octane number of at least
95 RON.
All models: as a temporary measure, if the recom-
mended fuel is not available, you may also 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 a 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

Observe the notes on operating fluids

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 rec-
ommended by Mercedes-Benz. Observe the notes
and mixing ratios indicated on the tank.
