from what i have read, the 4 cyl get about the same mileage as the 6 cyl but the 6 has way more power and torque!
I am getting approx 16 mpg in town and 20 -21 on the hwy (6cyl). about 300 km per tank, but my tank is only 15 gal US. not much of a range! looking at the tank mod!

 

I wud suggest if your going to get a lift go for the 4" this way you will if you decide to put 33's or even 35's they will fit without any rubbing and go for offset rims (normal is 3.75 offset) so as not to have them hitting your undercarriage when u make a turn.

 

With $40 of gas (~$1.34 per litre), I get 200km, no more, no less. (2003 TJ stock)

With my van with same amount i can get 300km.

 

There has been so many posts on this subject - It all depends on how you drive, What kind of equipment is on it? How many people are usually inside? Do you run over 95 km (55mph)? Do yu run on the open road at 140km then drop down to 100 then back up to 140km? I had mine stock at one time same year as yours and I am sure I was just over 20 mpg but now more like 15 mpg and I don't jackrabbit start or do over 100 km on the open road..remember its got the aerodynamics of a brick.If one wants great mileage one does NOT buy a jeep.

 

its mostly just driving around town to school and back ect.
thanks for the info

 

Get the 6 cyl. if not you will later regret that you did not.
Better pickup, better engine, about the same gas mileage.

 

Hi Tobijas,
I have a 99 Tj 4l 5 speed and I get a VERY consistant 19 mpg. I have 31's on and a cold air intake with 4:10 gears

 

Get the 4.0 and gas mileage???...hahahahaha

 

The 4.0 is definitely the way to go. Gas mileage between the two isn't that great but power wise the gap is huge. Especially with bigger tires!!!
