i have a 2004 XLT supercarb 4X4 5.4L and i get about 13-14 city and abut 16 highway, if i am on the interstate going right at sixty on cruise controll i can get up to 20, but that doesnt happen much. It normally gets about 14 MPG
I've got the 3.55 in the rear (2004 5.4 supercrew). I've hit 22 on the highway with the air off and tailgate down with no headwind. I'll typically average 19-20 on the road (at 75 mph) and only about 13 in town, but I give it a fair amount of grief from every light! Running 60-65 would probably put me over 20 easy, but no way I'm going that slow for any distance.

It has been scientifically prooven that driving with the gate down actually costs you gas milage.
I dont remember the exact details but its something to do with the way the bed will actually fill with a pocket of non moveing air and the rest of the air will flow over the tailgate. But when you drop the gate the bedsides work as two huge fins that distorte the air flow.
I seriously envy you guys getting 13 mpg. I do not understand how you guys get that, maybe it's just my truck, I average 12.4 mpg. I never go over 2 rpm on take off from a red light and I drive like a grandpa to conserve gas. Ac off or on does not make much of a difference nowadays, I read somewhere that it only changes gas mileage by .4%, and taking your foot off the gas is the big change at around 20 some percent, and also correct tire pressure...but whatever who cares, I just don't know how you guys get what I consider great gas mileage, y'all must live out in the middle of nowhere with no traffic lights.
15.4 on the dot in rural city driving. Usually around 19 on hwy. Hopefully my tuning will give better results. Also considering the Acetone idea floating around the internet. Had a friend go up 4 MPG with 3 oz acetone on a 94 Mustang.
ATuck23, i just graduated from LSU, do you go to LSU or are you just a fan?
I went to school with one of the O-linemen several years ago. He graduated from LSU back in '03. We went to high school toether and played basketball together. He graduated a couple of years before me and I started watching him and just fell in love with the traditions.
I've been at a private college in Mississippi for a while now but am considering going to LSU or UAB for my last two years and Med School. It just depends on who offers more money-if any.
