Probably already been said, but your 6sp Sahara probably had 3.21 gears and the Rubi is 4.10/4.11. Too, with only 1400 miles on it, it's not yet broken in. The fuel economy continued to increase slowly during the first 3-5k on my JK.

The Wrangler has never been advertised as a commuter vehicle intended to provide competitive fuel economy on the interstate highway system. State highways are still 55mph for the vast majority of the US.

Im only getting 14 as well. But my Islander only has 662 miles on the clock so Im not sweating it yet. With my 07 Sahara on an extremely heavy foot I was getting 16 city, and 17.8 on the highway. But yeah bigger tires, different gears make a difference.

i didnt read through all these but i just put banks exhaust on my 2010 rubi and i went from 14mpg in town to 18 in town and 19 on the highway going 75. it could be a combo of that and i just changed the oil and used royal purple full synth. idk? it was the same day and it jumped drastically and that was on a 1000 miles road trip so it wasnt just "good" gas

My 08 rubi got 20 plus at 65 but I drive more like 75 most of the time and it would average about 17mpgs. With 35s, stock gears and an auto trans I still get 16mpgs at 75. I do live in LA (lower Alabama) to the roads are flat.
