Update on my second tank of May:
Turned out better than expected, drove 428.2 miles on 10.018 gallons of gas making 42.8 MPG, calling it 43.
I used the A/C quite a bit on this tank too, might be able to do better now that my windows are tinted. Just think of what I could do if I went back to stock tire size, my guess is I could crack 50 MPG on my first tank, and that's with an Auto!!
Damnit, now I'm getting curious,.
