"Break in hints for the first 2000 miles (3000 kilometers)
The following tips will be helpful in obtaining optimum performance from your new Porsche. Despite the most modern, high-precision manufacturing methods, the moving parts must still wear in with each other. This wearing-in occurs
mainly in the first 2000 miles (3000 km).
Therefore:
1 Preferably take longer trips.
2. Avoid frequent cold starts with short-distance driving whenever possible.
3. Avoid full throttle starts and abrupt stops.
4. Do not exceed maximum engine speed of 4200 rpm (revolutions per minute).
5. Do not run a cold engine at high rpm either in Neutral or in gear.
6. Do not let the engine labor, especially when driving uphill. Shift to the next lower gear in time (use the most favorable rpm range).
7. Never lug the engine in high gear at low speeds. This rule applies at all times, not just during the break-in period.
8. 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 disks. New brake pads and disks 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 disks 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."
