Consumption 2.2 dti

Hello people! Since the end of April I drive an annual car (Vectra B Caravan, 2.2 dti EZ 05/02). Up to now I am quite impressed by the engine power. The oil consumption, of which I have read in various forums, did not occur until now (after approx. 2500 km). Only with the consumption, well… Up to now I have unfortunately hardly driven a “normal” tank filling. Either I have had Vmax-car rides (which I usually avoid) or “hurdy” road rides. For a while I had to pull something with a 1.5-ton hanger – etc. Long speech short meaning: since I got the car, I did not come under 7.5 ltr./100km. At the moment I am at 8 ltr. That seems to me almost a little high. With how much fuel do you drive your 2.2 dti? Tschau, Cyberherby
