Like I stated before, a 2WD rig with a 5 speed, and 225/75/15's, and 3.08 gears (I think)...I should be doing better than 16 mpg combined highway/city driving. I think I'm going to swap the oxygen sensor as a PM measure; it's a 50 dollar experiment, but it couldn't hurt. I'm hoping that the dirty Arab's gas pump was just off.

If those bastard's gas pumps are off calibration just a hair- say off one gallon for every 20 gallons pumped; just think about how much extra money they make every day. They have no incentive to have the pumps calibrated. I guess that's where trusty ol' big brother is supposed to step in...

I'm barely gettin 200 miles out of a tank(according to my odometer) but I know my odometer is off. 1993 Jeep Cherokee 4.0L stock 247,000 miles 32x11.5x15 tires and 3.55 gears.

i get about 21 city and 24 highway

i have a almost stock jeep cherokee and am getting 13mpg in city being light on the pedal and i got as high as 22mpg on highway but i need new spark plugs and o2 senors so i am hoing that will help with mpg's and i am planning on getting k and n intake and maybe a flowmaster

I'm not sure yet....but the 92 in F/T 4HI has already burned thru almost a 1/2 tank of gas and it's got 110mi. on the trip clock....I'll let you know what the final verdict is when I fill up again...

Keep in mind ya'll, that winter blends of fuel have been proven to not be as potent; at least from a mileage standpoint. You'll be able to go more miles during the summertime. This is hard for me to explain, because the winter fuel is more volatile, which would make you think that there are more BTU's in a gallon of winter gas.

I just changed my Oxygen sensor, and I can already tell a difference. I've gone 100 miles on a 1/4 tank. (running 93 octane)

if you want a dead on calculation of mpg fill up till its topped off reset the counter drive say 50-100miles top off the tank again.divide the number of miles you drove by the number of gallons you had to replace. any other method is just geussing big time! and you could be off by alot since theres reserve tank.ive always wondered why jeeps are so hard on gas. my 5.0l mustangs get around 14 city and a amazing 26mpg in my 86gt 5 speed but it has 2.73 rear gears so it sits at 1600rpm doing 60mph.
im not sure what to expect from my 86 2.5l 4speed and am wondering if it should be at 3grand doing 60mph ?? seems a bit high.

i was getting about 12m/gal.. this was with 32's and stock 3:55 gears
now i have 35's and 4:88's but am in the break in period, so time will tell

i have an '87 4cyl 4spd, and i get about 22mpg on average, if i dont go offroad... ive got no cat and a cheap performance exhaust(not legal, but where i live they get stolen anyway...), and 235/75/15s, i got less due to my spare being on the top of the rig, so i went to a 215/75/15 spare inside i cant fit my fullsize in the stock spot.

Well, we have a 92 stock Laredo with a 4.0, 4x4, automatic and we get 15 mpg in city, on the long haul, going up hill, going down hill, turned off, parked, it's amazing and maddening! I want that 16!!! SOME kind of difference!

I have 92 jeep cherokee laredo 4.0L 4X4 gets 20 mpg on highway with ac on and about 17 mpg in town.

with a 4.0 and automatic i got 18 when mine was stock and now with 3" lift and 31"s i get 12mpg, anyone get more with 31"s??

i got 31s and i get like 140 out of a tank.
somethings wrong

I get around 16 city 20 highway on my 94 with stock everything but I just installed a new muffler today so I'm hoping for better...Tj

<~ 31's with a bad MAP and I get around 13MPG. I think I have an upstream O2 (again. go figure...) going too...
Which that reminds me....
