It's better to drive your P-car at the higher rpms than to stay low in the 3K range. K keep it under 3K until it's at the 195F temp, but once it's there I keep the gears low and stay in the 4-5K range when cruising. Try it for awhile and you'll notice how much smoother it drives and it will stop making all of those annoying clicking and sticky valve noises at idle. (Btw, you should keep the rpms low until warmed up because the oil does not flow well at lower temps The engine is not well lubed until warm.)

There was a great article in the February, 2005 Panorama called "Falling In Love With A Porsche" that explains the differences in performance depending on how you drive it regularly. It's a re-print from 1971, but still pertains to todays P-car engines.
