Mercedes-Benz GLE 2022 Operator's Manual page 791

Compatibility indications for fuel:
1 For petrol with maximum of 5% ethanol by vol-
ume
2 For petrol with maximum of 10% ethanol by
volume
According to European standard EN 16942, the
compatibility indications for fuel on the vehicle
can be found on the information label on 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, it may produce unpleasant odours.
The recommended octane number can be found
on the information label on the fuel filler flap
( page 21).
/
For maximum engine output: refuel using only
super unleaded petrol of at least 98 RON. Alterna-
tively, you can also refuel using premium-grade
unleaded petrol of at least 95 RON.
In exceptional cases, if the recommended 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 of an even lower RON.
Further information on fuel can be obtained at a
filling station or a qualified specialist workshop.

* 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 qualified specialist workshop
(e.g. 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.
