You did pretty well Bart, considering your distance.

Here's my tally.
$337.51 total fuel purchases
1700 miles driven (275 of which was off road ~70% of that was lo range)
102.661 gallons consumed
16.5 MPG, not too bad for a "stout little bitch" (funny story on that nickname, ask me later)
Highest rate paid - Glenwood Springs, CO $3.589 (Sunday return trip 5/20)
Lowest rate paid - Parker, CO $3.159 (Friday departure 5/11)

We are 350 miles from Moab, but the exploration really tacked the extra on. I didnt add up my incidentals (oil, tranny fluid, etc) That was ~$30.
