Today I entered a fuel-up. When I hit return to complete it, ALL of my prior entries were recalculated and now show incorrect individual and average MPG. Until today's update, my average was over 45MPG, with the recent trend at 49.5MPG. Now it shows an average of 30+MPG. I tried updating the last entry, then deleting it; but the miscalculation persists. If you look at all the entries, the data is correct EXCEPT the calculated miles between fill-ups. Example: on 8/15 mileage was 44,128 mi.; on 8/23 it was 44,512 mi., a difference of 384 miles; but the site is calculating the miles travelled between as 281 miles; so calculated MPG is WAY below actual. Can this be fixed, or do I have to delete and re-enter all 20-some fuel-ups?
Interesting; so, somehow the site has reconverted all my historical elapsed miles per tank as if they had been entered as kilometers and misconverted them to miles?That's messed up. Not sure what I could have done to make that happen...
Sorry for the issues. We are looking into this and should be able to get your page to update properly without you needing to edit any of the fuel ups. I've already contacted our tech guys so they can figure out what's causing this issue. I'll send you a private message once it's fixed.
I had similar problems after entering 4 entries this weekend from a road trip.
Fuelly.com calculated km/L based on half the travelled number of kms with the same number of Litres consumed! MySQL retrieved Decimal digit Odometer readings with 1 digit of decimal, but Odometer has no place for tenths of km.
