There could be a few reasons for your fuel indicator problems. Have you disconnected your battery recently? The computer takes a while to get used to your driving conditions. It will affect the Miles to Empty. Your sending unit could be going bad, or going out. Depends on how much work you want to put into sovling this problem. As long as you know there is gas in the car then you'll be all right. If this is an on going problem, you can try and diagnose it but there is a potential for a lot of time and effort to be spent. If it were me and it wasn't a showcar I wouldn't worry too much.
