Fuel consumption 911 4S FL (direct injection, hand switch)

Hello, I’m a little surprised about the oil consumption: In just under 10000km I had to refill oil 3 times (each min. 1 litre). Although I never received a warning message, but at the oil control the indicator was then at the minimum. After a litre refill it showed up full. Is such oil consumption normal? I didn’t have it with any car. Do you have it with your new 911ers too? I am grateful for feedback. s4fun
