  Why would I go buy a honda when I have had a company truck with gas card for 10 years? I buy $300 in gas a week right now and don't even think about it.  And a honda wont get back across the levee and down onto the sand bar to go duck hunting on the river.  This is just a conversation on how to squeeze a little mpg outta my toy.

    Come on,
    If you really want good mileage, spend a couple grand on a used Honda instead of Bronco upgrades.  You are pushing a 5000 lbs brick through the air.  It doesn't matter what you do to it, it's not going to get good mileage.  End of story.  You might get better mileage if you put it on a trailer and towed it around behind a diesel truck.

      gearing has absolutely nothing to do with mileage in a Bronco.  I've tested extensively, from 3.50 to 4.88, and the only thing that matters is your cruise speed. 50mph might get 18mpg. I never beat 17, but some claim to, although set ups vary. Mine was generally with 35" mudders, 5.5" total lift, and SEFI.various transmissions.

      90-100mph, 10-12mpg. 
      70-80 mph 13-14mpg.
      55-65mpg 15-16mpg average
      50-55mph I got 17mpg the one trip (full tank- hwy) I tried it.  

      As far as I'm concerned, I'm going to run out of time before we run out of oil, so I drive fast :)

      YMMV  :)

        Reading all that we do, it looks like someone with a 5.0 and an OD tranny like a ZF gets maybe 18 mpg.  What gears is that with?

        So if I were to keep the 3.50 gears, install a 5.0 and a ZF, any guess what I could get?

        According to gear calcs, an OD at .75 and 34" tires, at 70 mph I get 18XX rpm at 70 with 3.5 gears and 21XX rpm with 4.11.

        What do you think that would do to mpg? Stock 92 mustang 5.0.

        Just wondering thoughts.  I was gonna ask best mpg setup as an excercise but quickly realized I would get a discussion on 4bt probably.  Thats a bit outside my motivation based on my current resources.
