ok i have a 1997 f150 4.6L and im trying to coax as much gas mileage as i can out of it i bought the truck used 2 years ago and have maintained it well it aready had a k&n drop in filter in it new fuel injectors and i put autolite double platinum sparkplugs in it. sadly i think i've only had her on a full tank of gas maybe 3-4 times since i've taken ownership i have looked into the jet chips as well just looking for other ideas or comments
What do you mean by "sadly i think i've only had her on a full tank of gas maybe 3-4 times since i've taken ownership"?
Are the tires stock size?
By well maintained, does this include all fluids, transmission, fuel system, throttle body, COPS, etc.?
If you decide to purchase a tuner (despite the overwhelming evidence against them improving MPG), please stay away from Jet. Look into SCT or Gryphon/Edge with custom tunes.

What is your current gearing and tire set up? what do you carry in the vehicle other than your self? These in addition to your driving habits will be the biggest influence on your mileage.

i mean that in the 2 years ive had my truck ive only had the tank full like a handful of times tire size is 256/70R17 but i believe a previous owner put them on cause the tire size sticker in the door says for 16in tires at a suprisingly low 29psi and on the up keep i am an auto technician and have maintained the fluids ect. as far as the rear ratio i have no clue if its still stock or if it was changed with the tires sizes i do know that my speedometer is off by 5mph slower that is and mostly is just me and the occasional trailer hauling scrap metal
