Break in hints for the first
2,000 miles/3,000 kilometers The following tips will be helpful in obtaining opti-
mum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, it cannot be completely avoided
that the moving parts have to wear in with each
other. This wearing-in occurs mainly in the first
2,000 miles/3,000 km. Therefore: fPreferably take longer trips.
fAvoid frequent cold starts with short-distance
driving whenever possible.
fAvoid full throttle starts and abrupt stops.
fDo not exceed maximum engine speed of
4,200 rpm (revolutions per minute).
fDo not run a cold engine at high rpm either in
Neutral or in gear.
fDo not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
fNever lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period. fDo not participate in motor racing events,
sports driving schools, etc. during the first
2,000 miles/3,000 kilometers.
There may be a slight stiffness in the steering,
gear-shifting or other controls during the break-in
period which will gradually disappear.
Break in brake pads and brake discsNew brake pads and discs have to be “broken in”,
and therefore only attain optimal friction when the
car has covered several hundred miles or km.
The slightly reduced braking ability must be com-
pensated for by pressing the brake pedal harder.
This also applies whenever the brake pads and
brake discs are replaced. New tires New tires do not have maximum traction. They
tend to be slippery.
fBreak in new tires by driving at moderate
speeds during the first 60 to 120 miles/100 to
200 km. Longer braking distances must be an-
ticipated.
Engine oil consumption During the break-in period oil consumption may be
higher than normal.
As always, the rate of oil consumption depends on
the quality and viscosity of oil, the speed at which
the engine is operated, the climate and road con-
ditions, as well as the amount of dilution and oxi-
dation of the lubricant.
fMake a habit of checking engine oil with every
fuel filling, add if necessary.

Engine Oil 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 observe the chapter “EXERCISE EXTRE-
ME CAUTION WHEN WORKING ON YOUR VE-
HICLE” on Page 178.
fRegularly check the oil level using the on-board
computer after the vehicle is refuelled.
Please observe the chapter “OIL DISPLAY AND
MEASUREMENT OF THE ENGINE OIL LEVEL”
on Page 101.
The difference between the minimum and maxi-
mum marks on the segment display is approx.
1.2 liters.
Each segment of the display corresponds to ap-
prox. 0.4 liter.

Engine Oil RecommendationRecommended oil viscosity ranges dependent on ambient temperatures
fUse only engine oils approved by Porsche.
If in doubt ask your authorized Porsche dealer for Porsche tested and approved all-season oils. Ambient temperature

Oil change The engine oil has to be changed at the intervals
listed in your Maintenance Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 268.
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. 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 en-
gine 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 dirt
which penetrates into the engine through combus-
tion 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 tem-
perature given in the engine oil recommendation
table.
