I drove my civic 1250 miles from Kentucky to Colorado drafting the Uhaul with a 2007 mustang being pulled behind it, first stop was 32.61 MPG, second 39 MPG, 3rd 40.54 MPG, 4th 41.08 MPG, and then the last fill was after all the uphill climbing @ 36.42 MPG... All I have to say about that trip is that Kansas is the worst state to drive through... We stopped 5 times because the uhaul drank gas... it was getting 6mpg the whole time. Most of the drive was @ 75 mph
Even though I have a manual, it was full of crap for the whole trip...
I was still really impressed with the gas mileage though, made me happy
Used to a POS 3.8L V6 getting 14-18.
