With my V70II D5 (163hp) the BC calculates the average consumption totally wrong. Was just at the tank and after 890km 62l filled. That is 7.5l/100km. But the BC shows an average consumption of 6.6l/100km. I can’t imagine that this deviation from after all about 1l should be normal. How are your experiences. Ohso, with the last time refueling I noticed this already. There was also such a high deviation. Since I have not had the vehicle that long, since Feb. 06, I have not noticed this yet.
