981 Boxster Spyder Chat
It's perfectly normal in the first 1000-3000Km; my car, for instance, consumed about 1 liter in the first 2000Km break-in period.
After that it's less than 60ml per 1000Km, and believe me, it's driven quite hard these days! ;)
One thing is very important, though, never, ever overfill the oil...
