2015 Rubicon 2-Door JK, Auto-trans., with a 3.5" Rubicon Express Super-Flex short arm suspension, 35" BFG KM2 Mud-Terrains, 4:56 gears, and the tire diameter & gearing reprogrammed with a FlashCal. I average 14-15 MPG around town and 17-18 MPG highway at 65 mph. If I bump the highway speed up to 70, It'll drop to 16-17.

'12, 2-door, 6 speed, Rubicon (stock 4.10's), heavy steel bumpers, winch, probably 200lbs of gear in the back, 4-door Recon spring "lift", 35/12.50/17 General Grabbers on ProComp rims. Average is 15ish mpg with mixed city/hwy driving. 12ish if just city (it's a really hilly area, which doesn't help in the slightest), 17ish if pure hwy.

2007 JKRU 4.10 gears after market bumpers, winch, bolt in add on cage, 3.5" lift with 35 x 12.5 x 17" Goodyear MTR's I got 13-14 mpg moved up to 37 x 12.5 x 17 MTR's I get about 11 MPG. If your worried about MPG my advice is don't drive a jeep for commuting. Jeeps are toys which one pours money into never get it back so MPG is really the tiny part of ownership when you modify a jeep. I picked up a used motorcycle for commuting leave my jeep at home.
