Fuel
When the ignition is on, the fuel level is displayed
on the instrument panel.
f
Please see the chapter “FUEL GAUGE” on
page 111.
Warning!
Fuel is highly flammable and harmful to
health.
f
Fire, open flame and smoking are prohibited
when handling fuel.
f
Avoid contact with skin or clothing, since injury
to your skin may occur.
f
Do not inhale fuel vapors, since they may make
you ill and possibly cause death if inhalation is
prolonged and occurs in a closed space.
To prevent damage to the emission control
system and engine:
f
Never drive the tank dry.
f
Avoid high cornering speeds after the warning
lights have come on.
f
Please see the chapter “FUEL ECONOMY” on
page 264.
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 fuels with octane ratings of
less than
98 RON/88 MON
are used, the engine’s knock
control automatically adapts the ignition timing.
Porsche recommends that you use fuel with
at least 95 RON/85 MON
in your vehicle.
The emission control system can be damaged in
various ways (e.g. fueling incorrectly, shortage of
fuel, tow-starting).
f
Please see the chapter “HOW EMISSION
CONTROL WORKS” on page 263.
Note on operation
Information on the fuel quality can normally
be found on the pump.
If this is not the case, ask a fuel 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
Avoiding driving at full throttle.
In some countries the available fuel quality may
not meet requirements and can result in coking
around the inlet valve.
In this case, the fuel may be mixed with the
additive sold and recommended by Porsche after
consulting a authorized Porsche dealer.
Porsche part number 000 043 206 89.
f
Observe the instructions and mixture ratios
stated on the container.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet.
