Good work.
I wish I could double EPA, in my cobalt that would be 74mpg, closest I ever came was on a short trip back from the gas station of 69mpg but never could achieve more than 52mpg on a tank. High 40's lifetime average is all I get
After this wonderfull 42mpg cold weather high speed / in town tank it will go down a bit.
My saving grace will be the insight, except when I need to carry 2 other passengers
