Using a slightly modified version of Douglas Thom's spreadsheet that he generously uploaded here, I've kept continuous records since buying the HAH. I see a gallon of gas costing $1.82 back in Feb, an mpg around 31 for around $.06 per mile for an early tank of fuel; a week ago, gas was $2.18 a gallon, but the cost per mile was still around $.06, thanks to a 36 mpg tank and hybrid technology. Something to think about.
