Wrangler owners - a question for you

My daily driver is a 2005 Wrangler Rubicon Unlimited. I average 16-18 mpg. Keep in mind I run a 33" tire with 4.10 gears. If I regeared to 4.56's I would probably get back to the 18-20 mpg it got in stock form. If you want a Jeep, get a Jeep. If you want good MPG get a TDI Jetta.
