get a prius. please dont though

 

Good luck on that one

 

Well, if you're checking your mpg via your speedo and you haven't corrected the speedo gear, then the number you're getting is wrong.

Gears will do the best for you, more so than any performance mod will.

13.50s on a 10" wheel has to weigh more than 12.50s on 8" wheels.

Yea the automatic probably has something to do with it as well.

So, get some 4.56s or 4.88s installed.

Then worry about bolt on performance.

 

Thanks for all the input guys. I will regear, add a CAI and exhaust a little later on

 

If you don't mind me asking what tires do you have? Haven't seen many 33x13.50s.... interco?

 

Look in my sig there's a link to my build thread. I have Nitto Mud Grapplers. 33x13.50x15s

 

Would 703's CAI and a header help?

 

I've got a 93 on 32X11.50's 170k miles and average about 200 miles per tank, I've come to terms with it.

 

When was the last time you changed your o2 sensors ?? To get the best mpg of your set up make sure you change both your front and rear o2s they decrease Mpgs when bad no matter what you do...

 

98 31x10.50 240,000 miles 280 miles/tank

 

build a stroker...?

 

Actually one of my o2 sensors is bad.. The check engine light is on and I ran a diagnostic and one of them is bad

 

I get 18 on 31's with 3.07's behind an ax-15, I'll be running 4.56 on 35's by the end of the year. With an ax-15 that would be equivilent to 4.88's on 35's. not far off from 4.56's on 33's. I'll be reporting back. Promise.

 

’98 limited 4 dr, 116934 mile 4.0 with fresh tune w/02 sensors, working a/c(not that I’m using it now), auto, 4:56’s w/aussie’s in both ends, 35" BFG’s @ 30 psi , speed-o gear changed to match, 5-1/2 lift, JCR front bumper w/winch, heavy home made rear bumper w/swing out w/matching 35" BFG & 48" high lift mounted to it, 60 lb. tool box in the rear.

20 mpg in your dreams dixie

13-15 mpg hwy @ 67 mph(sweet spot for mine).

13+ daily driving to work an back, 53 miles round trip with less than 2 miles under 50 mph. i drive like an old man...cause i am.

on a side note my overhead reads within 2-3 th of my actual mpg.

 

hey guys, been owning cherokees for 12yrs now, and here's my best results:
loose clutch fan- huge draw and biggest power and mileage gain
improve intake to closest to outside air
tb spacer if you're light on peddle (make one from 1" Oak or Comatex)
improve exhaust but keep back pressure, not wide open
move IAT sensor off intake to the box or intake setup, just off intake itself
160 thermostat
gasket match intake ports to head ports, easy but awesome results

Start with this stuff. not very costly at all and trust me, on 39.5 stock xj axles with auto trans 3.54 ratios, biggest jeep yet, and my mileage with all this stuff done is still pushin 17ish with easy on peddle most of time. I work on nothin but cherokees for 12 years now so this is best results. Hope this will help you out. God Bless You.
