    My 89 K5 (stock) w/ a 700r4 & 350 (3.42's) & 32" tires gets up around 17 mpg. I have not checked it to get an exact number. My 97 K1500 w/ a 4" & 33's and 3.73's was getting 17 the last time I checked it.. which was a pretty good while back. Either way, I'm happy with the MPG on both, for what they are, I can't complain.

    shoot, both my engines need a refresh, getting 11 average combined in my K10- 32's/3.73's/auto
    and about 10 combined K20/28's :D /3.73's/manual that should dump significantly with the 38's

    do you mean gpm?

    Yeah,gallons per mile. :D Seems like it.I'm getting right around 9 if I"m trying to be good and way less if I have my foot in it.Mine's really not much better on the highway-got the areodynamics of a brick.If i'm running 70 or 80 and let off the gas completely it's like hitting a wall.

    16.5 mpg freeway, 4.56's, no overdrive and 39.5" TSL's. It gets about 15 mpg in town...






















    That would be with a 6.2 though. With my 350 I was lucky to get 9-10 freeway and worse in town.

    I get between 12-15 mpg combined but trail mpg drops right down to around 6 Turns into a total pig. I'm running a 350/325 hp crate motor with a stock throttle body and 3.73's turning 33's in a 1990 Jimmy. But when you get right down to it, we really don't pilot these babies for thier fuel economy. :haha:
