Just hit 1700 miles and average 17.5 mpg with C/H mix but mostly city. 2 door 6 speed 3:21 gears and 32in rubi wheels and tires. Alot better then the 10 i got with my YJ 4cyl 5.5inches of lift and 35's and highway was was worse maybe 8mpg LOL

 

My summer average seems to be around 20.5mpg (little less with the top off). In the winter it seems to land either side of 18mpg.

 

27.6 MPG

 

I only see over 2200 RPM once or twice a tank unless i'm on the interstate which then i'll keep it around 65. That's how I keep the MPG high.

 

I am trying to figure out why I am getting only 14 mpg (Calculated) in mixed driving in my 08 Sahara Unlimited with 3.73's. I recently returned it to all stock and I drive like an old lady. Pathetic.

 

You diesel guys...... Just keep rubbing it in!

I wish I had a oil burner.

 

yup but then again diesel is $6 a gallon over here

 

I am about 16.2 or so on an average city and hwy, with 4.10, auto on a sahara 2dr best I ever got was about 21mpg as per onboard and that was driving from New York to Chicago and back within a 48hr period

 

2007 X, stock (for now), 6-speed. 15,000 miles.

If I do a lot of city driving, generally around 17.5-18mpg.
Highway/Road Trip, 21 or so, although I've gotten as high as 23 once.

 

I usually get between 19-21 mpg 08 auto with 3.73's. 37,000 miles so I a have some history here
