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 dri-
ving 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 break 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 lub-
ricant.
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 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 dus-
ty, 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 dri-
ving 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.
Therefore, the engine oil should be checked re-
gularly and kept at the required level.
– Make it a habit to have the engine oil level che-
cked 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
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
