correcting incorrect data
 

Hi, a few months ago, the iphone app didn't record my data, so at the next fillup, the mpg was approximately double normal. I know there's a missed fuel up box, but that only seems to work for a current fillup. Is there a way to correct old data? otherwise my mpg average is in error for me and for anyone else who checks it. If there's no way to correct, it makes the site less useful

I'm new here, and I'm using my desktop instead of my Iphone, but you could go into the last entry and edit the stats to match your missing entry and then re-enter your last fill up.

Steve is right, you need to login to the website and then edit the fill-up from your vehicles page:

Note the little pencil icon at the very left of the fuel logs that takes you to the edit page.
