Break in hints for the rst 2000
miles/3000 kilometers
The following tips will be helpful in obtaining
optimum performance from your new Porsche.
Despite the most modern, high-precision manufac-
turing methods, the moving parts must still wear
in with each other. This wearing-in occurs mainly in
the first 2000 miles/3000 km.
Therefore:
Preferably take longer trips.
Avoid frequent cold starts with short-distance
driving whenever possible.
Avoid full throttle starts and abrupt stops.
Do not exceed maximum engine speed of
4200 rpm (revolutions per minute).
Do not run a cold engine at high rpm either in
Neutral or in gear.
Do not let the engine labor, especially when
driving uphill. Shift to the next lower gear in
time (use the most favorable rpm range).
Never lug the engine in high gear at low
speeds. This rule applies at all times, not just
during the break-in period.
Do not participate in motor racing events,
sports driving schools, etc. during the first
2000 miles/3000 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 discs
New 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
compensated 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.
Break 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 and fuel consumption
During the break-in period oil and fuel consumption
may be higher than normal.
Please observe the chapter ”TECHNICAL
DATA” on page 328.
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
conditions, as well as the amount of dilution and
oxidation of the lubricant.
Make a habit of checking engine oil with every
refueling, add if necessary.
