Just put 2217 miles on our '05 Civic EX driving to Southern California and back to visit relatives and see the big 3 San Diego attractions - Sea World, Zoo and Wild Animal Park.
Averaged 35.3 mpg - best stretch was 38.7 mpg over 330 miles coming home March 18. We took the Civic instead of our '98 Mazda MPV for the gas savings - MPV gets about 19 mpg on trips like this, so we probably saved $150 using the Civic. We had less room, but managed ok.

3/8/2007: $2.219, St. George Costco (85 octane)
