C 70 2.0 D -Vebrauch

Have my C70 2.0 D for 3 days,so far everything is ok, only the consumption has scared me a little… The average consumption is about 9.1 liters!! (I only let the engine spin up to a maximum of 3000 tours and do not “step” it) I find that a bit much or is that normal???? Example my old Alfa 156 2.4 D I risked with 6.8 liters and kicked it like nothing good… Do I have to accept this consumption or regulate it still down??
