1997 4.0L, auto, 4x4
171,500 miles
Stock with mostly oem replacements for worn out parts.
Runs great.

On my route to and from work which is about 75% highway, 95 miles round trip, and never getting it above 65mph, I usually get 21-22.

More around town driving or a heavier foot and it will get about 18 pretty consistantly.

With 170K miles on my '99 Cherokee LTD - using K&N Air filter, DynoMax Exhaust, Splitfire Plugs and a regular fuel-vitamin supplement of Marvel Mystery Oil [at a mix ratio of 4oz/10gal regular fuel], I'm getting 15-17mpg locally and 19-22mpg highway.

95 sport 2dr 200K miles AX15 when i was stock 2wd i was getting low 20's (20-23) every tank, i do mixed country and city driving.

Now i'm 4x4, tired AX15, locked 8.25, 3.5" lift, stock tires as off now and i get 18-19 every tank. I removed the mech fan, installed 99+ intake, header, cat delete and have a pretty gutted interior

Chucks96XJ

1996 Country
16 mpg stock
mostly highway. i should be up in the 18 range, but i just did the tune up and still have to seafoam the thing...

dilljeepo

stock 99 sport Just ran seafoam and got an extra mpg since then- 22MPG average, I drive half in city half on highway, but I don't drive like a grandpa, I just don't bother accelerating up hills. I don't drive the jeep for mpg though.

hey i like the thread, i guess i shouldnt be too suprised by some of the responses, but damn... well, here goes:
the mods: DIY short ram and 2"bb.
the recent work: plugs/wires, cap/rotor, TPS, blew out lines, cleaned pump/filter, tons of seafoam and injector cleaner.
today i will be replacing my IAC valve and i hope that improves my MPGs, but as it sits now, usually no more than 20. if i go off road, or have fun w/ the gas pedal, no less than 15.
ordering some wrangler duratrac's (235/75r15) so im sure that will have an impact. ive got some wrangler SR-A's now and man do they SUCK!!!
check out the duras, though...

Stock 1992..2WD..2door..5 speed.4.0...General Altimax tires 225/70's pumped up to 45 psi..slight front end lowering 1 inch rear up same amout.. modest lip air dam... 3:07 rear end with that 22% O/D works out to a 2:39 final drive... run 15/50 Mobil 1 syn. with a shot of 8oz German Liqui-Moly in oil and their manual trans moly additive in gearbox and rearend.I know for a fact that Mercedes and Porsche use this same additive in their manual/rear ends.Always get 21-23 to work...60 mph .mostly highway. On long trips interstate just checked out twice this month at 27.5 at 60-65...above 75 the mileage does dip to 21-22...staight street Jeep...First post last year had better mileage posted but found out I was not filling tank up to top ...gave unreal mileage figures but now after a year and half driving I can post these correctted stats...and the Liqui-Moly has taken away the classic ticking at idle the 4.0 's seem to have..nice.
