Poor Ed and I both have 550HP Roush 427R's w/3.46 final. Sunday we both got 21 MPG through the back woods to Murphys. We also both get about 5 to 7 in town.
With a 17 gal tank, it gets more miles per tank tank my Z3 or Tahoe. (Just for reference) If you need to go 500 miles on a tank the 22 gal is for you. tom
