it will be necessary to bleed the fuel system
( page 232).
Y
Petrol (EN 228)
!
Refuel using only unleaded premium
grade petrol with a minimum octane num-
ber of 95 RON/85 MON conforming to
European standard EN 228.
You could otherwise impair engine output
or damage the engine.
i
As a temporary measure, only when the
recommended fuel is not available, 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 available petrol qual-
ity may not be adequate and could cause
coking 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 292).
Y
Turbo engines
!
Refuel using only unleaded Super Plus
with a minimum octane number of
98 RON/88 MON conforming to European
standard EN 228.
You could otherwise impair engine output
or damage the engine.
i
If the recommended fuel is not available
and only as a temporary measure, you may
also use premium unleaded petrol,
95 RON/85 MON. This may reduce engine
performance and increase fuel consump-
tion. You must avoid driving at full throttle.
