Thanks for sharing. Looks like your graph supports my hypothesis.

I don't go on Fuelly, what does the majority of the data represent?
Here are two graphs I posted a few months here Myth Busters - MPG Trend Over Time
that weren't too popular. I picked the 20 fuelly users with the greatest number of fillups (at the time) and cut and pasted their fillup data into Excel. I plotted all their mpg points (the faded curves in the background) and inserted a linear trend line on each (the dark lines). Most users had 30 fillups or more, so say 9,000 miles on their vehicles on average.
As you can see, the trendlines are pretty flat over 9,000 (or so) miles. Some go up a little, some go down.
