Filling with fuel
When the ignition is on, the fuel level is displayed
on the instrument panel.
f For further information on this:
Please observe the chapter “FUEL GAUGE” on
Page 122.
Warning!
Fuel is highly flammable and harmful to
health.
f Fire, naked flame and smoking are prohibited
when handling fuel.
f Avoid contact with skin or clothing.
f Do not inhale fuel vapours.
To avoid permanent damage to the functionality of
the catalytic converters and oxygen sensors, use
only unleaded fuel.
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.
f Never drive the tank dry.
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.
Porsche part number 000 043 206 89.
f Observe the instructions and mixture ratios
provided on the container.
1. Stop the engine and switch off the ignition.
2. Open the filler flap by
pressing on the rear part of the filler flap
(arrow). The vehicle must be unlocked.
