That is just my guess. I also think I read Fuelly bases it's number on only the last ten fill ups, but I am not positive about that. I'll look at the FAQ later.
I am sorry, I think you misunderstood me. I do reset it with every gas tank. For the same full gas tank, I calculate by hand and compare that to the dashboard readout. I noticed that your fuelly said 0.0 MPG, so I was wondering how you were reporting 44MPG, what method you were using. My dashboard routinely reports 40MPG, but the reality is significantly lower sometimes by as much as 10%.
