Consumption kia ceed 1.6 crdi 115ps

moin moin love kia municipality I got a kia ceed sw as a company car and now wants to do my first impression of this car kunt 😉 ,he has now 80000 km on the clock and should have been driving, I have been traveling with him now 3000 km and am joyfully overwhelmed by the vehicle , lot of space and runs well ,now to the edwas negative topic of diesel consumption :-(,if you drive over land and quickly the courses changes the speed low is one with about 6 liters dabe i find i is a normal value but since i am on assembly I drive 80 percent on the highway and there starts the miserable, once you exceed the 140 km/h it is over with sprit save because you can look at the tank display like the liters purzeln rrrrrr,if you then 160-180 drive what for the car is not a problem he pulls 9 liters per 100 km from the tank ui ui ui ,if I then read the reports on spritmonitor I do not know how the people on such values as 4.5 liters i m average come ,I find anyway the consumption with highway ride for much too high that must go nevertheless better OR ?mancher Wirt say KRAFT comes from KRAFTSTOFF but that certainly can not be ! until the days
