couple of usability suggestions for "add a fuel up"
 

I just filled up, and here are my nits:
- It'd be nice if the fill up form was ordered price, gallons, then odometer.
- In the success screen, there's info about this fuel up, then averages below. The MPG for this fuel up isn't listed. It'd be nice if it was listed with the +/- last fill up.

The form ordering thing fits my workflow where I jump out of the car, fill up, then pull out my cellphone to do the fuelly thing. I can put in price while the car is filling, then total gallons at the pump, and finally jump in the car to fill out odometer reading and submit.

Not a bad idea on the first one, I agree that I follow the same path when filling up at the pump (I'm assuming you are talking about m.fuelly.com).

On the second point, it's likely that you entered a partial fill-up? Check out the previous answer to see why.

It's a full fill up, but I'm half wrong. I just double checked my cellphone browser: the MPG is there, it's just missing the +/- bit.

I vote for keeping it like it is
