Price per gallon graphed along with MPG?
 

Just a thought, it would be nice to see it on the same graph as the recent fillups which show MPG. Might be cool to see how our MPG goes up (or down lol) as prices per gallon fluctuates. Probably wouldn't be too hard to do since most members already record the price per gallon at the time they filled up. Definitely something I'd love to see implemented in the future! By the way just joined looking forward to using the site!

We tend to stress the stats on Fuelly that you have control over, so you can practice better driving habits, etc.

Price is really out of our hands for the most part (aside from picking which station you get fuel at) so we're at the whims of the marketplace.

Seeing a graph of price over time doesn't really help me as a driver too much with figuring out how much I'll pay next time, since price can fluctuate up or down 10+ cents every week.
