2.5TD drunkards or gas station spooks?

Hello guys! I’m interested in your diesel bill. My omi needs between 7.5 and 9 liters of danger it will be in the Eifel (so up and down with up to 25% climb). A third of the route hangs a 2to horse hanger on the hook, the rest is highway and highway. I always strive for a quick but economical driving style. My record was below 6ltr (motorway to Zurich), but I don’t always have that much time! (grins) So please also rub your driving style and The area where you live (journey). Greetings DottiDiesel PS: my Omi has already collected ~480tkm of honor.
