Consumption S60 D3

Hello Together, for a month I have been the owner of a Volvo S60 D3 Momentum. It is a leasing back runner, BJ October 2010 almost 30000km on the clock. So far I am really totally satisfied…the best car I have had so far. Processing, operation, driving comfort……just everything first cream. Only when I was filling up for the first time today my joy was a bit clouded. Consumption according to on-board computer at almost 700 km 6.5l/100km, as far as I thought so well. However, it is calculated 7.5l/100km!!! I am aware that this engine never reaches the consumption values from the data sheet, but with such a consumption I definitely did not expect. Just because I drive almost exclusively land road with Tempomat at 90-100km/h. As I do speed up and then turn it up and let it roll. I don’t even want to imagine how much of the swallows if I give him the spores properly. How do you see your consumption values (calculated and on-board computer). Bzw. How and when do you switch? Should I call to the consumer when consumption remains so high with Alex’s greeting profile.
