2010 Unlimited Sport: Recent trip to South Carolina (500 miles 1 way), computer said 20.1 mpg. manually calculated was 19.5. I thought this was pretty good as this was with a family of 4 and rear cargo area full (luggage, golf clubs, etc).

 

2008 Unlimited Rubicon with 3" lift and 35" Toyo MTs and I was getting 11.8 MPG. After buying the Superchips I am now getting 14 MPG average. The computer showed 16.6 MPG yesterday, but it is probably high. I have only had the Superchips for 2 fill ups, so I am hopeful it will get better.

 

been averaging 18mpg on the highway with my 35s/6spd

 

MPG...MainlyPuttingGas for me about $35 every 4-5 days

 

Wife's JKU Rubi auto 3" Lift, 35", 5.13's, and Superchip gets about 17ish in and around Boulder. Haven't had it on the Hiway on a long haul yet with the new gears.

My Rig gets 13-14 on the hiway. 9 or so on the trails. But I have a hemi.

 

Modded 2dr 6 speed w/4.10s & 33's = 17-18.5 mpg

 

How bout' MPGs = "Mostly/Pumping/Gas"........lol

 

2008 unmodded 4 door, 6 sp here. I've been tracking the mileage using an app on my phone for the past several months. Avg tank is 21.08 mpg.

 

2 dr auto X - no mods yet mostly back hwy driving during week.
summer avg 21-22 mpg but do get it up to 23 with soft top
winter avg 18-20 with hard top and all the fuel additives that get put in up here in New England.
not that it probably makes any difference at all, but I rarely have my back seat in.

 

Don't know........Don't care. I just drive it. When the gas needle gets to a 1/4 tank I fill it up
