All my life I wrote my fuel-ups in Excel. Since it is not handy to do it in 2 different places I would like to have the possibility to export my data or to back-it up to my disk, just in case Fuelly will have an end. Of course I hope not and wish you success.
Also I would like to add another car. I think 8 is a good limit when you have 4 sons and they also like Motorbikes ;-)
