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.

Thank you.

Stil have the same problem, if o go to edit the entry to check I have everything right I see its using the OD that I just entered to call kms not the OD from the previous entry.

Can you get me a screenshot? One of your logbook, one of the individual entry, and anything else you feel would be helpful in trying to replicate this on my end.
Thanks!

Please try logging out and then back into the app. This will force a refresh. Let me know if the issue remains.

That did the trick, but why do I need to log out and back in for it to work correctly.

Magic...

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.

Cheers!

Still need to log out and then back in to get the correct functionality, same symptoms as before.

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.
