Android app? And explanation of engine types..!
I had considered making a Fuelly Android app for a class a few months ago, but then I realized, what benefit would it gain? Without an API, the application could merely script the m.fuelly.com site, parse through the html, and so on. Looking at m.fuelly.com, the site is super simple and loads really fast because of how small it is (6kb), so I wonder what benefits could be gained by presenting another interface.
The only usability benefit would be the ability to quickly type in numbers and then the app would later enter them in. There'd also be the benefit of a custom icon and visibility in the app store, of course.
I suppose, if I'm bored enough this summer and enough people really want it, I'd be open to suggestions for how it should look and work and could make a simple one.

Recovering faster from partial fill-up
Users of Greasemonkey and similar plugins may find this script useful: http://userscripts.org/scripts/show/66252
It parses the fillup and fillup log pages for partial fillups and calculates and displays an MPG for the first fillup after a partial fillup, with an asterisk to indicate that it is calculated.
I mostly made it for my own car and use, but maybe other people will find it useful.

Huh!
This is why I'm not going for a math minor :) Being a programmer is enough for me.

Yes, I understand that. However, you could sum the total miles and gallons between the fill-ups, including the partials, and I think it would still work.
For example:
From a full tank, I drive 180 miles, and buy 3 gallons of gas. This partial tank would be impossible to calculate, of course.
From that partial tank, I drive another 30 miles, and then fillup with, say, 8 gallons. Taken by itself, this tank is also impossible to calculate.
However, if you add them together, you would have driven 210 miles on 12 gallons of gas. This calculation should be perfectly accurate.
This is the exact same calculation that is done for the average MPG, except it's taken over consecutive partials and the next fillup. This means that several consecutive partials could also contribute to the MPG for the next fillup, instead of just the most recent. In fact, they would have to for this idea to work.
Am I missing some knowledge that would prevent this from working?

Odometer Field for database
I think boethos wants some way to correlate his efficiency with his car's mileage. I could imagine another label along the bottom of the Recent Fuelups graph that displays the car's mileage for each fuelup.
People who currently don't track with the odometer would need to set some start date to their mileage, such as "Today my odometer said X", and then the system would fill in their mileage for past fuelups. Then they could keep using the tripometer method.
