MPG rating showing 0.0 and "-" for two months

[mauricem]

First, I love this site. I've been using a spreadsheet for the last two years so I'm anxious for the new data I can pull in with this site.

I'm trying to figure out why my MPG rating has been 0.0 for the last couple of months. I imported a lot of data and that seemed to go ok, but now, when I look, even the data that I manually enter is showing blank. I've tried looking through the data for inconsistency, but can't find any. Any advice?

Many of your fuel-ups are marked partial. When you enter a partial fuel-up, Fuelly doesn't calculate an individual MPG for that fuel-up, and the one immediately following. Fuelly needs a new full-tank baseline to start calculating MPG for individual fuel-ups. However, the fuel-ups do contribute to your average fuel economy. Here's a bit more info: How do I account for partial fuel-ups? and Why do I have to fill the tank all the way up every time I buy fuel?
