High oil consumption for the Audi 80 Avant B4

Hello together, wanted to ask if it is normal with the Audi 80 Avant year 94 2.0 115hp that it consumes 1.5 liters of oil on 800-1000KM. I have now 1.5 years, have immediately made an oil change with Mobil1 0W40 fully synthesized. In the course of the time I have then noticed the high oil break. Is that also so with you, you know a solution? For your help I am very grateful to you! Greetings Volker
