Mods That Wont Hurt MPG?

sorry but the thought did cross my mind that maybe you bought the wrong kinda car. i mean you either go as fast as stock and save gas, or you go faster and feed your engine.
im not trying to be rude or nuttin dont get me wrong.
but anyone who buys a stang and plans on driving it 7 days a week should have already decided that your willing to spend a pretty penny on gas, not to mention the prices these days. when my stang was put back on the road last spring after winter i spent $120 in 5 days!
yes on gas.

i would like to see the numbers for total 2005 mustangs sold. 6cyl vrs 8cyl nation wide. ive only seen maybe 10 05 GT's this whole year and that would be pushin it. im sorry but mustangs should only have 2 engine options
v8 & v8/w charger. just my opinion.
