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 or
other controls during the break-in period which will
gradually disappear.
Break in brake padsNew 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 tiresNew 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
anticipated.
Engine oil consumptionDuring 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.
fPlease observe the chapter “ENGINE DATA” on
Page 356.

Radiator fansThe radiator and radiator fans are in the front of
the car.
Warning!
Danger of injury. The fans can start running
as a function of temperature, even with the
engine switched off.
fExercise extreme caution when working in the area of the radiator fans.
Engine OilEngine 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 lubri-
cant.
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 lev-
el at all, even after 600 miles (1000 km) or more.
This is because the oil is gradually becoming dilut-
ed 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, cli-
matic conditions are warm, and the load is high,
the oil should be checked more frequently, as driv-
ing conditions will determine the rate of oil con-
sumption.
– 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 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 RecommendationRecommended oil viscosity ranges dependent on ambient temperatures:
Use only engine oils approved by Porsche.
If in doubt ask your authorized Porsche dealer for Porsche tested and approved all-season oils. Ambient temperature
(seasonal)SAE Viscosity Range
higher than
-13°F (-25°C)0 W-40
5 W-40
5 W-50
lower than
-13°F (-25°C)0 W-40

Maintenance, Car Care
Oil changeThe engine oil has to be changed at the intervals
listed in your Maintenance Schedule.
fPlease observe the chapter “CAPACITIES” on
Page 362.
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. Only by using oils approved by Porsche
the needed engine oil performance is guaranteed.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 classEngine 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.
ViscosityLike 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
the SAE class is given as a number and the letter
“W“ (as in winter), for hot viscosity 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.
E.g.: A 5 W-40 oil and a 5 W-50 oil have the same
viscosity when cold; when hot the oil with the num-
ber 40 is thinner than the oil with the number 50.
Oils with two viscosities are called multigrade oils;
oils with only one viscosity are termed single-
grade oils.
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.
