For a single guy, my fuel bills suck. I drive 30 miles each way to work every day. On the plus side I now carpool with 2 others. Driving either my 98 Cherokee with the 4" Lift, 31's, and Accurate power 4.6 L stroker, enjoying watching the gauge move while accomplishing 13-15 mpg on good days with no headwind. On the other side of the coin, is my 04 Ram 2500 w/Cummins power (~435 horse at the rear wheels) that gets about 16 mpg. Gas bill permonth is likely in the $500 range. Like i said, alot for a single guy
