Danger!
The RF energy from a cellphone can cause a
sparking on bare metal, much like aluminum
foil in a microwave oven. The spark could
ignite gasoline fumes present while refuling.
Static discharge from your body can ignite
gasoline fumes present when you get back
out of the vehicle and touch the fuel nozzle.
In either case, resulting fire can cause
serious damage to the vehicle, serious injury
or death to persons in immediate vicinity.
f Do not use a cellphone while pumping gas.
fDo not re-enter the vehicle while pumping gas.
1. Stop the engine and switch off the ignition.
2 . O p e n t h e f i l l e r f l a p b y p re s s i n g o n t h e re a r p a r t of the filler flap ( arrow).
The vehicle must be unlocked. 3. Slowly open and remove the tank cap.
Put the tank cap into the holder ( arrow).
4. Add the fuel additive recommended by Porsche if necessary.
5. Insert the pump nozzle fully into the filler neck.
The handle of the pump nozzle must point
downwards.

Maintenance and Car Care
Fuel Recommendations Your Porsche is equipped with catalytic
converters and must use UNLEADED FUEL
ONLY .
Your engine is designed to provide optimum
performance and fuel economy using unleaded
premium fuel with an octane rating of 98 RON
(93 CLC or AKI) . Porsche therefore
recommends the use of these fuels in your
vehicle.
Porsche also recognizes that these fuels may not
always be available. Be assured that your vehicle
will operate properly on unleaded premium fuels
with octane numbers of at least 95 RON
(90 CLC or AKI) , since the engine’s “Electronic
Oktane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service
intervals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
T h e u s e o f U N L E A D E D F U E L O N LY i s c r i t i c a l l y
important to the life of the catalytic
converters. Deposits fr om leaded fuels will
ruin the converters and make them
ineffective as an emis sion control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps that
dispense unleaded fuel ha ve smaller nozzles. This
will prevent accidental pumping of leaded fuel into
cars with catalytic converters. Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we
recommend you do not take your car to areas or
countries where unleaded fuel may not be
available.
Octane ratings Octane rating indicates a fuel’s ability to resist
detonation. Therefore, buying the correct octane
gas is important to prevent engine “damage”.
The RON octane rating is based on the research
method. The CLC (U.S.
Cost of Living Council
octane rating) or AKI ( anti knock index) octane
rating usually displayed on U.S. fuel pumps is
calculated as research octane number plus motor
octane number, divided by 2, that is written as:
The CLC or AKI octane rating is usually lower than
the RON rating:
For example: 95 RON equals 90 CLC or AKI.
Fuels containing ethanolDo not use any fuels containing more than 10
percent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems
occur with your vehicle:
– Deterioration of driveability and performance.
– Substantially reduced fuel economy.
– Vapor lock and non-start problems, especially at high altitude or at high temperature.
– Engine malfunction or stalling.
