When a vehicle sees tracks, higher speeds or harder loads it will burn off these impurities, thus causing less wear and tear on your parts. These vehicles will also see more fluid changes than cars that are parked in a garage and allowed to sit there looking pretty. That is why many Porsche owners will autocross or track their cars on a semi regular occurrences. The vehicles that are garage queens have a tendency to have more problems than the vehicles that are regularly driven.

No engine should be started unless it will be allowed to reach its operating temperature (minimum 180 degrees) Porsches seem to need the higher oil pressures that come at higher RPMs (3500 + ) for best lubrication in the engine, IMS included. And specifically in the case of the OP Vario-Cam engines should not cruise @ 2200rpm - 2500rpm to prevent Vario-Cam advancing back & forth or off & on.
