Tank 145 - 8 February 2008

This morning I filled up at the Fredericksburg Costco, again, with
10.489 gallons at $2.819 per gallon. I went 422.4 miles on this tank,
making for an average fuel economy of 40.27 mpg, which is pretty good
for February.

As I drove past the Woodbridge Costco, I saw gasoline there was $2.759
per gallon. But there was a tanker truck that appeared to be refilling
the underground tanks at the time, and I heard you shouldn't refuel when
the underground tanks are being refilled, as more sediments and such
could make it into your tank. But over the course of 10 gallons, the
cost difference would have been about seventy cents, which adds up over
time, but for today I must not worry about it.

This last tank helped my fuel economy for 2008 to avarage over 38 miles
per gallon, about 0.4 mpg better than 2007's overall fuel economy. But
it's still early.
