fExercise extreme caution when working in the area of the radiator fans.
Engine OilIt is important to perform oil changes regularly in
accordance with the intervals specified in your
Maintenance Schedule.Engine oil consumptionIt is normal for your engine to consume oil.
The rate of oil consumption depends on the quality
and viscosity of oil, the speed at which the engine
is operated, the climate, road conditions as well
as the amount of dilution and oxidation of the
lubricant.
If the vehicle is used for repeated short trips, and
consumes a normal amount of oil, the engine oil
measurement may not show any drop in the oil le-
vel at all, even after 600 miles (1000 km) or more.
This is because the oil is gradually becoming
diluted with fuel or moisture, making it appear that
the oil level has not changed.
The diluting ingredients evaporate out when the
vehicle is driven at high speeds, as on an express-
way, making it then appear that oil is excessively
consumed after driving at high speeds.
If the conditions you drive your vehicle in are
dusty, humid, or hot, the frequency of the oil
change intervals should be greater.If the vehicle is driven at a high rate of speed,
climatic conditions are warm, and the load is high,
the oil should be checked more frequently, as
driving conditions will determine the rate of oil
consumption.
– The engine in your vehicle depends on oil to lu-
bricate and cool all of its moving parts. There-
fore, the engine oil should be checked regular-
ly and kept at the required level.
– Make it a habit to have the engine oil level
checked with every refueling.
– The oil pressure warning light is not an oil level
indicator.
The oil pressure warning light indicates serious
engine damage may be occuring when lit, if
engine rpm is above idle speed.

Maintenance and Car Care Always observe the following points:
– Use only engine oils approved by Porsche.
This is a precondition for optimum and
problem-free operation of your vehicle.
– The engine oil is changed regularly during
servicing.
It is important that the service intervals,
particularly the oil change intervals, are
observed in accordance with the specifications
in the Maintenance Schedule.
We recommend that you have the engine oil
changed at your authorized Porsche dealer.
– Oils approved by Porsche can be mixed with
each other.
– Porsche engines are designed so that no oil
additives may be used.
– A label located in the engine compartment
provides you with details of the most suitable
oil for your engine.
Your authorized Porsche dealer will be pleased to
advise you.

servicing.
fIn dusty conditions, clean the filter element
more frequently and replace if necessary.
Further important information concerning “mainte-
nance” can be found in a separate chapter.
fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 250.Changing Particle FilterThe fresh air passing through the particle filter into
the passenger compartment is virtually free of
dust and pollen.
fIf the outside air is polluted by exhaust fumes,
press the recirculating-air button.
A dirty filter can be the cause of reduced air
throughput.
fHave filter replaced by your authorized
Porsche dealer.
fRegular replacement of the filter is part of
servicing.
Automatic Transmission Fluid The torque converter and the transmission are
lubricated with Automatic Transmission Fluid
(ATF).
fPlease see the chapter “CAPACITIES” on
Page 359.
Do not tow the car or run the engine without ATF
in the transmission. The automatic transmission
may be damaged by even a tiny speck of dirt, only
a clean funnel or spout must be used when adding
AT F.
The ATF and transmission oil has to be checked
and changed at the intervals listed in your Mainte-
nance Schedule.
We recommend that you have the ATF and trans-
mission oil changed at your Porsche dealer, who
has the required lubricants and the necessary fil-
ling equipment.
If you suspect an oil leak in the transmission, have
your authorized Porsche dealer check it out imme-
diately.
Manual Transmission OilThe transmission oil has to be checked and chan-
ged at the intervals listed in your Maintenance
Schedule.

Fuel RecommendationsYour Porsche is equipped with catalytic conver-
ters 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 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
Octane™ knock control” will adapt the ignition
timing, if necessary.
It is important to observe the regular service inter-
vals, and particularly the oil change intervals, spe-
cified in your Maintenance Schedule.
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.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 ratingsOctane 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 oc-
tane rating) or AKI (antiknock 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 corresponds 90 CLC or
“AKI”
fDo not use fuel additives without Porsche
approval.
Fuels containing ethanolfDo 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.
