Do not use the following:
R E85 (petrol with 85% ethanol)
R E100 (100% ethanol)
R M15 (petrol with 15% methanol)
R M30 (petrol with 30% methanol)
R M85 (petrol with 85% methanol)
R M100 (100% methanol)
R petrol with additives containing metal
R diesel
Do not mix such fuels with the fuel recom-
mended for your vehicle.
You will usually find information about the fuel
grade on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
CLA 200, CLA 250, CLA 250 4MATIC,
CLA 250 Sport, CLA 250 Sport 4MATIC: as a
temporary measure, if the recommended fuel is
not available, you may also use regular unleaded petrol with an octane rating of 93 RON.
All other models: as a temporary measure, if
the recommended fuel is not available, you may
also use regular unleaded petrol with an octane
rating of 91 RON. This may reduce engine per-
formance and increase fuel consumption. Avoid driving at full throttle and sudden acceleration.
Never refuel using fuel with a lower RON.
i In some countries, the available petrol may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
Information on refuelling (Y page 153).
Mercedes-AMG vehicles ! Only refuel using super unleaded petrol with
at least 98 ROZ, that conforms to European
standard EN 228 or an equivalent specifica-
tion.
You can otherwise impair engine output or
damage the engine.
Fuel of this specification may contain up to
10% ethanol. Your vehicle is suitable for use
with E10 fuel. You may refuel your vehicle
using E10 fuel.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol with an octane rating of
95 RON. This may reduce engine perform- ance and increase fuel consumption. As much
as possible, avoid driving at full throttle.
! As a temporary measure, if the recommen-
ded fuel is not available, you may also use
unleaded petrol in emergencies with an
octane rating of 91 RON.
Doing so results in noticeably higher fuel con-
sumption, and the engine power output is
noticeably reduced. Avoid driving at full throt- tle.
If no fuel other than petrol with 91 RON or a
lower grade is available, you should have the
vehicle adapted to run on this fuel at a quali-
fied specialist workshop.
CLA 250 (only for certain countries).
! Only refuel using sulphur-free unleaded pet-
rol with at least 95 ROZ, that conforms to the
European standard EN 228 or E DIN or an
equivalent specification.
You could otherwise impair engine output or
damage the emission control system.
i In some countries, the available petrol may
not be sufficiently low in sulphur. This fuel can temporarily produce unpleasant odours,
especially on short journeys. As soon as sul-
phur-free fuel (sulphur content < 10 ppm) is
used for refuelling, the odours are reduced.
Additives ! Operating the engine with fuel additives
added later can lead to engine failure. Do not mix fuel additives with fuel. This does not
include additives for the removal and preven-
tion of residue build-up. Petrol must only be
mixed with additives recommended by
Mercedes-Benz. Observe the instructions for
use in the product description. More informa- tion about recommended additives can be
obtained from any Mercedes-Benz Service
Centre.
Mercedes-Benz recommends that you use fuel
brands that have additives.
The quality of the fuel available in some coun-
tries may not be sufficient. Residue could build
up in the fuel injection system as a result. In this case, in consultation with a Mercedes-Benz Ser-vice Centre, the petrol should be mixed with the
cleaning additive recommended by Mercedes-
Benz. Always observe the notes and mixing
ratios specified on the container. Service products and filling capacities

Diesel
Fuel grade
G
WARNING
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is a risk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel.
! When refuelling, only use diesel fuel that
conforms to the European standard EN 590 or is of equivalent quality. Fuel that does not
conform to EN 590 can lead to increased wear
as well as damage to the engine and exhaust system.
! Do not use the following:
R marine diesel
R heating oil
R bio-diesel
R vegetable oil
R petrol
R paraffin
R kerosene
Do not mix such fuels with diesel fuel and do
not use any special additives. Otherwise,
engine damage may occur.
! Vehicles with diesel particle filters:
in
countries outside the EU, only use low sulphur
Euro diesel with a sulphur content of under
50 ppm. Otherwise, the emission control sys- tem could be damaged.
! Vehicles without a diesel particle filte
r:
in countries where only diesel fuel with a high sulphur content is available, you will need to
carry out your vehicle's oil change at shorter
intervals. More information about the interval for oil change can be obtained from any quali-
fied specialist workshop.
Usually you will find information about the fuel
grade on the pump. If you cannot find the label
on the petrol pump, ask the filling station staff.
Information on refuelling (Y page 153).Low outside temperatures
In winter months, diesel fuel with an improved
cold flow quality is available. In Europe, the
EN 590 standard defines various climate-
dependent temperature categories. Malfunc-
tions can be avoided by refuelling with diesel
fuel that corresponds to the climatic specifica-
tions outlined in EN 590. At unusually low out-
side temperatures, it is possible that the flow
characteristics of the diesel fuel could be insuf- ficient. Accordingly, diesel fuel from warmer
areas may not be suitable for operation in colder
climatic conditions.
i Further information on country-specific fuel
properties and fuel types with low-tempera-
ture resistance can be obtained from oil com-
panies, e.g. at filling stations. Engine oil
General notes When handling engine oil, observe the important
safety notes on service products (Y page 327).
The quality of the engine oil is decisive for the
function and service life of an engine. After
extensive tests, Mercedes-Benz approves
engine oils that correspond to the current tech-
nical standard.
Therefore, only Mercedes-Benz-approved
engine oils may be used in Mercedes-Benz
engines.
Further information on tested and approved
engine oils can be obtained from any Mercedes- Benz Service Centre. Mercedes-Benz recom-
mends that you have the oil change carried out
at a qualified specialist workshop. Mercedes-
Benz approval is indicated on the oil container
by the inscription "MB-Freigabe" or "MB- 330
