Unleaded petrol

First read and observe the introductory information and safety warn-
ings on page 122.
Your vehicle can only be operated with unleaded petrol in compliance with the
EN 228 standard.
1)
All petrol engines can be operated using petrol that contains at most 10% bioe-
thanol (E10).
Prescribed fuel – unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON or higher.
In case of necessity, you can refuel with petrol with the octane ratings 91, 92 or
93 RON, if petrol with the octane rating 95 RON is not available
Fuel additives
Unleaded petrol in accordance with the EN 228 standard
tions for a smooth-running engine. We therefore recommend that no fuel addi-
tives are used. This can result in considerable damage to parts of the engine or
the exhaust system.
CAUTION
Even filling the tank with leaded petrol that does not meet the standards once
■
can lead to serious damage to parts of the exhaust system!
If a fuel other than unleaded fuel which complies to the above mentioned
■
standards (e.g. leaded petrol) is used by mistake, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur! We recom-
mend that you have the fuel system cleaned by a specialist garage.
1)
In Germany, DIN 51626-1 or E10 for unleaded gasoline with octane number 95 and 91.
If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
■
number than the one prescribed, the journey must only be continued at medium
engine speeds and a low engine load. Driving at high engine revs or a high engine
load can severely damage the engine! Refuel using petrol of the prescribed oc-
tane number as soon as possible.
Engine parts can be damaged if petrol with a lower octane number than the one
■
prescribed is used.
Even in the event of an emergency, petrol of a lower octane number than 91
■
RON must not be used, otherwise the engine can be severely damaged!
» .
In no case may fuel additives with metal components be used, especially not
■
with manganese and iron content. LRP(lead replacement petrol) fuels with metal-
lic components may not be used. There is a risk of causing considerable damage
meets all the condi-
1)
to parts of the engine or exhaust system!
Fuels with metallic content may not be used. There is a risk of causing consider-
■
able damage to parts of the engine or exhaust system!
Unleaded petrol that has a higher octane number than that required by the en-
■
gine can be used without limitations.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of petrol
■
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.
