I am getting like 15 mph stock and a lot of you are getting that lifted and locked and everything else I have changed plugs any other ideas

That's about right for city. Got that stock my self. Should go up in the summer with the warmer temps and better fuel formulation (not the winter blend).

Trade you mpg's...............................

Winter gas, and cold weather. Best you can do it keep fresh plugs in it, change air filter. pcv, check tire pressure as it goes way down in cold weather. I have had mine as bad as 12-13mpg with excessive ideling with heater on in below zero temps.

i didnt know they changed the blend of the gas for winter 15 thats highway but i only get 16 highway in the summer
tjkj2002 i would gladly trade mpg with you if we are tradeing jeeps too then i would have a reason to get such bad mpg
when i bought this i was getting close to 20 highway
what kind of plugs you all like???

Yea 15 MPG is right on. I avg about 15/16 in the winter and 17/18 in the summer. On Long trips I Avg about 19-21mpg.

^^plugs stock copper core ones are NGK-ZFR6F-11G gapped at .040. Double check your emissions sticker under the hood since yours is an 03. (that's what my 05 sticker says-should be the same) Otherwise use the Autolite double platinum. Either of those will give the best results according to others on the forum. Change them every 30,000 miles.

I am right in line with this ^.


Keep in mind, driving style has a TON to do with mileage.

 

[LibertyTC]

Driving style and weight and tire types/air pressure.
You can get more mileage by going up a few lbs in the tires.
Keeping it mild in the right foot department greatly helps.
Synthetic motor oil also help for flow in winter.
