I'd suggest a slight enhancement to the Fuelly web site. It's too hard to find the single-letter SMS designator for a vehicle. I know it's there; I've set them up several times. But if I forget what the letter is for a particular car, it should be easy to go to the web site and find it. I've just spent 5 minutes looking for it unsuccessfully. In my view, it should be displayed with the vehicle info on the dashboard.
