Refuelling - Mercedes-Benz E-Class 2010 Owner's Manual

It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours.
G Risk of fire
Do not use petrol to refuel vehicles with a die-
sel engine. Never mix diesel with petrol. This
causes damage to the fuel system and engine
and could result in the vehicle catching fire.
!
Do not use petrol to refuel vehicles with a
diesel engine. Do not use diesel to refuel
vehicles with a petrol engine. Even a small
quantity of the wrong fuel will damage the
fuel system and engine.
!
If the wrong fuel has been added by mis-
take, do not switch on the ignition. If you
do, the fuel could enter the fuel lines. The
fuel tank and the fuel lines must then be
drained. Inform a qualified specialist work-
shop and have the fuel tank and the fuel
lines drained completely.
Petrol (EN 228)
Fuel grade
!
Only refuel using unleaded premium-
grade petrol with at least
95 RON/85 MON, which conforms to Euro-
pean standard EN 228.
You can otherwise impair engine output or
damage the engine.
!
Do not use the following:
E85 (petrol with 85 % ethanol)
R
E100 (100 % ethanol)
R
M15 (petrol with 15 % methanol)
R
M85 (petrol with 85 % methanol)
R
M100 (100 % methanol)
R
diesel

Do not mix these fuels with petrol and do
not use any special additives. Otherwise,
this can lead to damage to the engine. This
does not include additives for the removal
and prevention of residue build-up on the
inlet valves.
i
If the recommended fuel is not available,
but only as a temporary measure, you may
also use regular unleaded petrol,
91 RON/82.5 MON. This may reduce
engine performance and increase fuel con-
sumption. Avoid driving at full throttle.
In some countries, the fuel grade available
may not be adequate and could cause res-
idue to build up around the inlet valve. In
such cases, and in consultation with a
Mercedes-Benz Service Centre, the petrol
may be mixed with the additive recommen-
ded by Mercedes-Benz (part no.
A000989254510). You must observe the
notes and mixing ratios specified on the
container.
For further information on "Fuel", see
( page 313).
Y
Diesel (EN 590, DIN 51628)
Fuel grade
!
Only refuel with diesel that conforms to
European standard EN 590 or German
standard DIN 51628 or the equivalent. You
can otherwise impair engine output or dam-
age the engine.
!
Vehicles with diesel particle filters: in
countries outside the EU, only use low sul-
phur Euro diesel with a sulphur content of
under 50 ppm. Otherwise, the emission
control system could be damaged.
!
Vehicles without a diesel particle fil-
ter: the engine oil should be changed more
frequently in countries in which diesel with
a higher sulphur content is available. More
information about intervals for changing
the engine oil can be obtained from any
Mercedes-Benz Service Centre.
!
Using fuel that does not conform to Euro-
pean standard EN 590 or German standard
DIN 51628 can lead to increased wear,
