Maintenance, Car Care
Engine-compartment blower,
radiator fan The radiator and radiator fans are in the front of
the car.
The engine-compartment blower is mounted on
the engine compartment lid.
Warning!
Risk of injury.
After the engine is switched off, the engine-
compartment temperature is monitored for
approx. 30 minutes.
During this period, and depending on tem-
perature, the engine-compartment blower
may continue to run or start to run.
fCarry out work in these areas only with the en-
gine off, the ignition off, and exercise extreme
caution.
Risk of injury. The radiator fans in the front
end of the car may be operating or
unexpectedly start operating when the
engine is switched on.
fCarry out work in these areas only with the en-gine switched off.
Engine Oil It is important to perform oil changes regularly in
accordance with the intervals specified in the
“Maintenance” booklet.
Engine oil consumption
It 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
level at all, even after 600 miles (1,000 km) or
more. This is because the oil is gradually becom-
ing 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
lubricate and cool all of its moving parts.
Therefore, the engine oil should be checked
regularly and kept at the required level.
– Make it a habit to have the engine oil level
checked at every fuel filling.
– 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 en-
gine rpm is above idle speed.
Engine Oil Level fPlease see the chapter “EXERCISE EXTREME
CAUTION WHEN WORKING ON YOUR VEHICLE”
on Page 206.
fRegularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please see the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 153.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.3 quarts (1.25 liters).
Each segment of the display corresponds to ap-
prox. 0.42 quart (0.4 liter).

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

Unleaded fuels may not be available outside the
continental U.S. and Canada. Therefore, we rec-
ommend you do not take your car to areas or
countries where unleaded fuel may not be availa-
ble. Octane ratings Octane rating indicates a fuel’s ability to resist det-
onation. 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 equals 90 CLC or AKI
Fuels containing ethanolDo not use any fuels containing more than 10 per-
cent ethanol by volume.
We recommend, however, to change to a different
fuel or station if any of the following problems oc-
cur 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. Portable Fuel Containers
Danger!
Portable fuel containers, full or partially
empty, may leak causing an explosion, or re-
sult in fire in case of an accident.
fNever carry additional fuel in portable contain-ers in your vehicle.
Fuel Evaporation Control Fuel tank venting The evaporation chamber and the carbon canister
prevent fuel from escaping to the atmosphere at
extreme high outside temperatures, when driving
abruptly around curves and when the car is parked
at an incline or in any other nonlevel position. Vapor control system and storage When the fuel tank is filled, vapors are collected in
the evaporation chamber by a vent line leading the
vapors to the carbon canister where they are
stored as long as the engine does not run. Purge system When the engine is running, the fuel vapors from
the canister will be mixed with fresh air from the
ambient air of the canister. This mixture will be
directed to the intake air housing by the tank vent
line, mixed with the intake air and burned during
normal combustion. RON+MON
