I kept on asking the Service man if there is some thing wrong that I see a better mileage

. But he is very cautious not take a stand. Some of my colleagues who has Exi say that they get 13-14 Km with a judicial AC usage and on highways about 22 KM (again AC is not continuously kept on). I have a kind of report which I made to see how the mileage varied between a very good road and a constant speed Vs Bumpy/Patchy road.
Very soon, I will post it in a proper format.
