Ford Mondeo Combi (Sprit consumption too high)

Hi Leutz! We’ve been driving Mondeo Combi BJ 2000 for some time now. The part has 1.8 liters and 115 hp. Unfortunately we barely get under 9 liters of fuel consumption. The car is mainly moved on short distances. From me very economical (inside mainly 5 gears) accelerate up to max 3000 turns. But I can’t get the part lower. Last calculation resulted in 9.5 liters. The best where mainly I drove was just under 9 liters. If someone else from the family driving more by car, we are sometimes even at 11 liters. Well with them it has not been sooo tragic before. I really don’t know why that is, but somehow it seems a lot to me. What can you do? Nice greeting Stefan
