To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
unleaded fuel only .
The engine is designed to provide optimum
performance and fuel consumption if unleaded
premium fuel with 98 RON/88 MON
is used.
If unleaded premium fuels with octane numbers of
at least 95 RON/85 MON are used, the
engine's knock control automatically adapts the
ignition timing.
Note on operation
Information on the fuel quality is normally provided
on the petrol pump.
If this should not be the case, ask a petrol station
attendant.
If the recommended fuel is not available,
you can also use unleaded regular fuel
(91 RON/82.5 MON) in an emergency.
However, this could reduce performance and
increase fuel consumption.
f
Avoid driving at full throttle.
In some countries the available fuel quality may
not meet requirements, and this can lead to
coking in the area of the intake valve.
In this case, the fuel may be mixed with the
additive sold and recommended by Porsche after
consulting a Porsche partner.
