i read alot about you guys getting upwards of 20mpg with your V6's. well i have a 1998 4.2L V6 regular cab long box with a 5 speed and 3.55 gears. it has 2.5 inch true duals and i get 13-14 mpg with it. now i am 18 years old and you would think i would drive it hard for being a kid. well i dont. i never rev the engine alot and i never really floor it either. just drive it from place to place. and the best i can get is 13-14. what is the problem with my pickup?
