Yea it only costs initially $20 more to fill up, but if its more like $40 a week ,cause you drive more, extra and your self employed and you only get tax compenstaion for .485 cents a mile and it costs you more like .60cents a mile you are getting hosed on all sides. I get taxed for my income, im paying more for gas, and im able to deduct less and less of what I pay out of pocket for business purposes. So it is a big deal, especially when tax code doesnt keep up with the current situation ;)
