11.890 gallons, the most ever put in my tank, after going 424.9 miles.
Fuel Economy was poor at 35.74 miles per gallon. I argue that it has
been very hot and my AC has been working overtime, although last year at
this time I had been averaging 37 and 39 miles per gallon.
However, my 22nd tank in 2007 came on June 25, and this year my 22nd
tank came on July 22, almost a month later in the year. I have also
gone about 300 fewer miles over the same amount of time, a reduction I
attribute directly to my carpooling. We don't carpool as much as we'd
like, but every day one of us hitches a ride is a little less gasoline
used to get us to work.
I have slacked on my charting and historical graphs, so I don't have
much more to share.
