1 liter of oil at 2300km? 2.0 FSI….

Hi together, I know that there was already a thread about the topic but never find it. I have now 4500 km with my 2.0 FSI and the first time I replenished with 2300 km 1 liter of oil because there was in the FIS oil shortage, it really missed oil checked. And yesterday I had to refill 1 liter of oil again and have now about 4500 km on it. That can not really be or? Let’s say that the liter costs 20 Euro it is also extremely annoying and from advance dur Is that normal? Or should I be a friend?
