Whoa! So already we have a new approach to calculating FE (as SOCCER wrote) and a corroboration to the fact that the auto-cut does not necessarily helps us to calculate the correct FE.
@Soccer: The auto-cut is indeed used by most of us to calculate the FE of our cars. On a top-up to top-up basis. Basically after the top-up we drive some 200-300 kms and then again get a top-up. This way we assume that the liters that went in on the second attempt is the amount of fuel the car consumed for the kms travelled. Only that now I am finding out that when the auto-cut cuts in probably the tank could have easily taken in another couple of liters.
Let it come guys... keep the ideas flowing
