You folks on Fuelly are the only ones we can trust when you get cars with such high mileage. It became obvious to me the other day during a fill up. My wife had made a trip to Chicago and wanted to know how she did on here trip. 277 miles, 2 bars left.
I went to the gas station and filled up to first click. At that point I was at 43 MPG, I wait a few seconds and go to a second click, now I’m at 40MPG.
Now if I was filling my F150 one click more would just mean .2 more MPG.
A little goes a long way and the averaging of Fuelly over time sure makes a difference. We are just not anal enough in our family to keep track of every fill up.
