FuelWhen the ignition is on, the fuel level is displayed
on the instrument panel.
fPlease 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.

Maintenance and Car Care
Refuelling
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.
Total capacity:
Panamera S: approx. 21.14 US gallons
(80 liters).
Panamera 4S/Panamera Turbo:
approx. 26.42 US gallons (100 liters).
The reserve is approx. 3.96 US gallons
(15 liters) for each.

6. Operate the pump nozzle and refuel the vehicle.
Do not add further fuel once the correctly
operated automatic pump nozzle has switched
off. Fuel could spray back or could flow over
when heated.
7. Replace the tank cap immediately after refuelling and close it until you hear and feel
it locking.
8. Close the filler flap and press on the rear of the filler flap until it engages securely.
If you lose the tank filler cap, you must
replace it only with an original part.
Caution!
Risk of damage. Decorative foils may fade
if they come into contact with fuel.
f Wipe off any spilled fuel immediately. Emergency unlocking of the filler flap
If the electrical unlocking mechanism is faulty,
the filler flap can be opened as follows:
– Pull the emergency release mechanism behind
the right luggage compartment trim panel in
direction of arrow .
The filler flap pops open.
Fuel Can
Danger!
Risk of fire or explosion if the fuel can is
damaged in an accident and fuel escapes.
Escaping vapors can be harmful to health.
f Do not carry a fuel can on journeys.
fObserve the relevant laws.

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.
