I have a 2008 4 dr sahara 6spd. I made a trip this weekend from my home to west virginia. On this trip i got 14.6 MPG (according to the thing in the dash board). I have 32.xx cooper discoverer STTs and a rough country 3.25 lift with a RR XHD front stubby. It doesn't seem like i should be getting efficiency this poorly. I'm looking for comments about this (whether you think it is right or wrong) or opinions on what i could do to make it normal. 85% of this trip was highway driving (60-75 MPH). Just recently installed the lift and was getting around 17 or 18 before the lift went on. Any questions post them and i will try to answer. Thanks guys.

 

2008 4door w/55000 miles, no lift w/285's atuomatic & my average mpg is 15.6.

 

my mileage is shit all the time. it was even when it was stock

 

Same here... 2007 1" BB 285's with an avg around 15

 

We went camping this weekend and pulled a 3500# pop up camper up to 8700 feet.Averaged 9.8 mpg . With 37" AUTO and 513s. About the same as my Dodge 2500 Hemi.

 

My milage on trips dropped about 2.5 MPG after installing the lift. Seems like it is just a factor of pushing more air while driving down the road.

 

thanks for the replies guys. Whenever i go up to 35s will be regearing. Will that have positive/negative effect? I have heard it has helped some and had no change with others (just more power)

 

Don't have a lift on my 2010 Wrangler Sport but when I installed 33x12.5 tires my MPG droped from 16.9 to 15.3. Purchased a Superchips Flashpaq, K & N CAI and MBPR performance exhsusts. MPG now 17.5 with same driving conditions plus a lot more low end power. Very happy with this set up. BTW my Sport is a 6 speed manual.

 

On my auto stock 3.73, I was getting 17 - 19 mpg. Now lifted 4" w/35" and Superchips, I get 14-15 mpg. I will be regearing next year when funds allow.

 

I wouldn't trust the gadget On the dash. Mine is never right on my stock 07 Rubi 2dr. According to the dash I normally get around 16 +/-, but if I calculate it out when I fill up I get anywhere from high 17's to almost 20. I've yet to break into the 20's, but I get oh so close.
