"Partial fuel-ups and fuel-ups following a partial fuel-up will not display an MPG"—the web site lets you know that, but not the iOS app. This would be good to know, particularly for those of us who only use the web site when the app seems to be screwing up.
I'll post any other issues in separate topics so as not to clutter this one. But my biggest one is also explained by the FAQ I referred to above. My Cavalier hasn't had two full fills in a row, so no MPG is displayed. (However, the web dashboard shows 46.0 MPG.) Every other app I've tried—if they correctly handle partial fills—shows the MPG after a full fill, so why not Fuelly/GasTracker?
I normally fill up each time. But recently did my first partial (Hiway gas was $0.45 more than a few miles down the road so I just got $10 worth)
When recording this purchase as a "Partial" and then recording the fill-up the next time. Should the program no add the miles and fuel of the partial to the next fill up and calculate using this data. Maybe add an asterisk to indicate the partial/fill-up mix of data.
