Engine Oil RecommendationPorsche recommends .
The right oil for your vehicle.1) Generally, you can find details of the
manufacturer approvals on the oil containers or as
a notice displayed by the retailer.
The current approval status is also available from
your Porsche partner.2) SAE viscosity class - Example: SAE 0W - 40
Specification 0W = Viscosity specification for
low temperatures (winter).
Specification 40 = Viscosity specification for
high temperatures.3) For all temperature ranges.4) For the temperature range over --13 °F (--25 °C).Always observe the following points:
– Use engine oils approved by Porsche only. This
is a precondition for optimum and problem-free
operation of your vehicle.
– Regular oil changes are part of servicing.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the “Maintenance” booklet.
– Oils approved by Porsche can be mixed with
each other.
– Porsche engines are designed so that no oil
additives may be used.
– A label is located in the engine compartment,
which provides you with information on suitable
oil for your engine.
Your Porsche partner will be pleased to advise
you.
Oil changeThe engine oil has to be changed regularly at the
intervals listed in your Maintenance Schedule.
fPlease see the chapter “CAPACITIES” on
Page 290.
We recommend that you have the engine oil
changed at your Porsche dealer, who has the re-
quired oils and the necessary filling equipment.
If you suspect an oil leak in the engine have your
dealer check it out immediately.
All current engine oils are compatible with each
other, i.e. when making an oil change it is not nec-
essary to flush the engine if you wish to use a dif-
ferent brand or grade of oil.
Since, however, each brand of oil has a special
composition, you should, if possible, use the
same oil brand if it becomes necessary to top up
between oil changes.
Porsche engines have long intervals between oil
changes. You can make best use of these long oil
change intervals by using multigrade oils since
these are largely independent of seasonal fluctua-
tions in temperature. Complies with
approval

Maintenance, Car Care
Refueling Fuel tank capacity is listed under “Capacities”.
Porsche does not recommend the use of fuel ad-
ditives.
Fuel is highly flammable and harmful to
health.
fPlease see the chapter “CAPACITIES” on
Page 290.1.Important: Stop the engine and switch off the
ignition.
2. Slowly unscrew the tank cap.
Hang the tank cap's plastic strap on the hook
on the inside wall of the filler flap.
3. Insert fuel-hose nozzle fully into the filler neck
with the handle of the fuel-hose nozzle facing
down.
4. Do not add further fuel once the correctly op-
erated automatic fuel-hose nozzle has
switched off.
Fuel could spray or could run over in warm
temperatures.
5. Replace the tank cap immediately after
refueling and turn it until you hear it and feel it
engage.
If you lose the tank cap, you must replace it
only with an original part to reduce the
possibility of a fire in the event of a collision.
Caution!
Risk of damage. Decorative film may fade if
it comes into contact with fuel.
fWipe off any emerging fuel immediately.
Fuel Recommendations Your Porsche is equipped with catalytic convert-
ers and must use UNLEADED FUEL ONLY.
Your engine is designed to provide optimum per-
formance and fuel economy using unleaded premi-
um fuel with an octane rating of 98 RON
(93
CLC or AKI). Porsche therefore recom-
mends 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 tim-
ing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals,
specified in the “Maintenance” booklet.
The use of UNLEADED FUEL ONLY is critically
important to the life of the catalytic
converters. Deposits from leaded fuels will
ruin the converters and make it ineffective
as an emission control device.
Cars with catalytic converters have a smaller fuel
tank opening, and gas station pumps have smaller
nozzles. This will prevent accidental pumping of
leaded fuel into cars with catalytic converters.

Maintenance, Car Care
Air Filter A dirty air filter not only reduces engine perform-
ance, but can lead to premature engine wear.
Regular filter replacement is part of the routine
maintenance service.
fIn dusty conditions, check the filter element
more frequently and replace if necessary.Combination Filter The fresh air passing through the combination fil-
ter into the passenger compartment is virtually
free of dust, pollen, and unpleasant odors.
fIf the outside air is polluted by exhaust fumes,
press the circulating-air button.
A dirty filter can be the cause of reduced air flow:
fHave filter replaced by your authorized
Porsche dealer.
Regular filter replacement is part of the routine
maintenance service.
Fluids/Oils for Manual
Transmission and Porsche
Doppelkupplung (PDK)The transmission fluids/oils have to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
fPlease see the chapter “CAPACITIES” on
Page 290.
Do not tow the car or run the engine without fluid/
oil in the transmission. The transmission may be
damaged by even a tiny speck of dirt, only a clean
funnel or spout must be used when adding fluid/
oil.
We recommend that you have the fluids/oils
changed at your Porsche dealer, who has the re-
quired lubricants and the necessary filling equip-
ment.
fIf you suspect an oil leak in the transmission,
have your authorized Porsche dealer check it
out immediately.
