    with my k5 engine dead, and gas prices getting out of hand, i may be selling it and getting a smaller 4x4. i really like the blazer, and it always impresses me offroad. but, keeping it fueled was kicking my butt.

    are you guys familiar with how many miles per gallon a jeep will get? i'm talking about the various open-top versions, like the cj5, cj7, wrangler, etc, with various engines. 4 bangers, jeep 6cyl, dodge 318, chevy 350 or 4.3L swaps, etc. any info you're willing to give would be appreciated.

    my friend's 1990 gets crappy mpg (about 12 on our last roadtrip), but we think his wimpy 2.5L 4banger might have a lot to do with it. just has to work too hard. considering my 4.3L gets about 20mpg in my extended cab c1500, i bet it would do great in a little jeep.

    I have several freinds with Jeeps the more modifed the get the worse the mileage will be.
    1 1980 CJ7 stock 6cyl T5 trans 31" tires 12 mpg
    2 1975 CJ5 350V8 turbo 350 35" tires 4.56s 11 mpg
    3 1985 toyota pickup w35s 4.3 carbed 5.13 gears 5 sp 13 mpg
    If you want something that gets good mileage get a sami I had one with a bunch of stuff done to it 5.13 gears 33s weber carb etc etc etc 21 mpg in town on the highway didn't matter that is what it got

    my buddy says he rarely does better then about 17 with his 4.0L in his XJ. And another friend says he never does better then about 25 with his TJ with a 4 banger. Buy a Saturn man, 37 MPG, 32 with the A/C on.

    My old 1985 Jeep XJ with a 4 cyl, 5 spd got 20 mpg steadily in stock form. It was a good runner with an excellent motor though.

    4x4 s-10 ZR2. Those guys get 19 on the highway. If you don't mind a 2wd, my 99 Jimmy gets 26 when I baby it on the highway. I average 22 city and highway.

    Truthfully? I'd find a hunk of crap little car or truck that gets over 30. You're not gonna want to go offroading too much in your DD anyway. The money you save on gas with a rice burner can go to your true off-roader.

    My '88 XJ got anywhere between 14 and 25 mpg, depending on the day. 4.0L with 5 speed. If you want practicality and mileage get an S10 with the 2.5L. My '85 4-banger got a steady 25mpg.

    My Dad has a 94YJ with 2.5L and an AX5. He gets like 23mpg with his 235 rubber and high teens with his 31" rubber. I got the same thing with my 89 Sonoma with the 92hp TBI 2.5L. He just rebuilt his Jeep's motor as well.

    Unless you only drive in the city, a Jeep doesn't make sense. My Dad's gets great city mileage (almost as high as highway) but doesn't do that much better on the expressway. You're lucky if a 4.0L AW4 XJ (Cherokee) gets more than 15mpg.

    man, those jeep numbers really suck. bummer. when i kept the k5 mostly on the pavement (25% highway, 75% crappy stop-n-go), i was getting around 15mpg. on a tank that saw lots of offroad action, it was more like 10 . i have a heavy foot in the mud. when i bought it, i could deal with that. gas was 1.50 or so. but, i've passed on a lot of fun wheelin trips to avoid paying hundreds in gas.
    now i know why the flintstones just used their feet through the floor.

    my 1994 c1500 is my dd, regardless of what other vehicle i have. the mileage isn't quite what my old honda got (before some dumbass ran a red light and smashed it, and me) but, i have an almost perverse devotion to it. ha.

    Find an old Scout II with the 4 cylinder engine. 196 cubic inches, pulls like crazy. My 75 got 22 mpg on the highway with 30" tires, 4.10 gears and four speed.

    We've had two Jeeps that we've put significant miles on. They are pretty reasonable to drive and fairly reliable. They are almost as easy to work on as a small block :D even with all their sensors and what not.

    '96 Grand Cherokee (ZJ)--still have it, wife's daily driver--gets about 17 mpg, 4.0L and 30" stock tires

    '91 Cherokee (XJ)--(R.I.P.) 4.0L with automatic (AW4)...drove it daily for about 4 years and got it to 184K before selling it off. I got close to 20 mpg with 235, 17 mpg with 31" tires and 3.55 gears, 19 mpg with 32" tires and 4.10 gears (4.5" lift), 17ish with 33" tires and 4.10 gears (4.5" lift) and about 15 mpg with 35" tires, 4.88 gears (6" lift and a WAY tired engine at that point).

    I live in Utah at about 4300 ft., so I'd assume the mileage would get a little better if you were closer to sea level?

    Note: Currently I'm building a Wrangler (YJ) with a TBI 350, 700R4 and 38" tires for off-road and 37" A/T for street use. I have no idea what kind of mileage I'll get out of that, but the donor Suburban was getting about 14-15 mpg if I kept it under 75 with 31" tires and 3.73 gears.
