Maintenance and Car Care
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
level at all, even afte r 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
expressway, 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 de
termine 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 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.
Checking Engine-Oil Levelf Check the oil level on the multi-function display
at regular intervals before refuelling.
f Please see the chapter “OIL LEVEL DISPLAY
AND MEASUREMENT OF THE ENGINE OIL
LEVEL” on page 121.
Warning!
Engine oil is hazardous to your health and
may be fatal if swallowed.
f Keep engine oil out of children's reach.
Used engine oil contains chemicals that have
caused cancer in laboratory animals.
f Always protect your skin by washing thoroughly with soap and water.
Top-up quantity
The difference between the minimum and
maximum marks on the segment display is
approx. 1.06 US quearts (1 liter).
One segment of the display corresponds to
a top-up quantity of approx. 0.26 US quarts
(0.25 liters).
f Never add more engine oil than required to
reach the maximum mark.

256
Maintenance and Car Care
1. Unscrew cap on oil filler opening.
2. Top up engine oil according to the display on
the multi-function display.
One segment of the display corresponds to a
top-up quantity of approx. 0.26 US quarts
(0.25 liters).
3. Carefully close cap of the oil filler opening.
After opening the hood, the oil level can only
be measured after driving for at least 6 miles
(10 km).
Oil changeThe engine oil has to be changed regularly at the
intervals listed in your Maintenance Schedule .
f Please see the chapter “FILLING CAPACITIES”
on page 329.
We recommend that you have the engine oil
changed at your Porsche dealer, who has the
required 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
necessary to flush the engi ne if you wish to use a
different 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 beco mes 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 usin g multigrade oils since
these are largely independent of seasonal
fluctuations in temperature.
If your vehicle is used frequently in stop-and-go
traffic in cold weather, the engine will not always
be properly warmed up.
Condensation from products of combustion may
accumulate in the oil. In this case, it is advisable
to change the oil more frequently so that your
engine once again has 100% efficient engine oil.
Engine oil performance class Engine oil is not only a lubricant, but also serves
to keep the engine clean, to neutralize the
contaminants which penetrates into the engine
through combustion and to protect the engine
against corrosion.
To perform these functions, the oil is provided with
additives which have been specially developed for
these functions.
The efficiency of an oil is expressed, for example,
by the API, ILSAC or ACEA classifications. Viscosity Like all liquids, engine oil is viscous when cold,
and thin-bodied when warm. The viscosity of an oil
is expressed by its SAE class. For cold viscosity
(measured at temperatures below 32 °
F/0 °
C) the
SAE class is given as a number and the letter “W”
(as in winter), for hot viscosity (measured at
212 °
F/100 °
C) the SAE class is given only as a
number.
The viscosity of an oil is, therefore, always the
same if it has the same number of an SAE class.
Oils with two viscosities are called multigrade oils;
oils with only one viscosity are termed single-
grade oils.
Single-grade oils can not be used in your engine.
The viscosity of the engine oil for your Porsche
has to be chosen according to the ambient
temperature given in the engine oil
recommendation table.
