Ok so this time it worked, but this was the first full fill I have done since discovering the problem. All the partial fills still show nothing, is this correct behaviour. I would have thought that even with a partial fill I could have got economy figures.
It matches what you see on your Fuelly profile, right?
7/1 and 7/10's fuel up were marked as partial and therefore do not display a MPG figure.
This is expected behavior because without filling the tank it's impossible to calculate how much fuel was used for the miles traveled on that fuel up.
However, your partial fills will contribute to your overall average MPG.
Fuelly's calculations rely heavily on you filling your tank to the top because it uses the difference from full to calculate fuel economy on individual fuel-ups.
Actually, it just seems to "fix it". Maybe a remnant of an older version. Maybe cache needing to be cleared. I'm not entirely sure. But, you wont have to continue to log out/back in going forward. This should fix it going forward.
Of course, let me know if it doesn't and starts acting funky again.
Ok so did a fill up today and it worked, the only thing I did different was to go next after selecting percentage driving, and then selecting next. But in the edit screen still shows the current mileage as the previous mileage.
