This usually eliminates the characteristic puff of blue smoke on start up (if you hold your mouth just right).
When I worked at a german car street shop it was normal procedure to drain the factory turbo sump tank along with the main oil tank and engine case.

We would also disconnect one end of the large S hose at the bottom of the oil tank and let it drain out and also the oil line coming back to the tank from the external thermostat.
It takes a little extra time to do that but it gets more dirty used oil out and thats a good thing.
Porsche oil changes took longer so the labor charge was higher than most other cars anyway.
