The best way to save on gas would be to get a small car for commuting and save the 4x4 for off-roading/mudding/rock crawling. My brother has two wranglers, a 91 or 92 (I know it has a carb) and a 95 or 96, with EFI. He bought the newer one because he couldn't get the older one to run reliably with the carb. What he should have done was buy a car, since he commutes to work/school, and worked on his first Jeep to use for off-roading, which he only gets to do occasionally.

You could try to fabricate some coroplast air dams to deflect airflow away from high drag areas like the axle and dif. You could attach them as such to be removed quickly. If you can afford it, buy two sets of wheels and tires, one for road and one for AT. Too bad lift can't be changed as easily as tires.

I've seen a increase in both FE and HP/torque with the installation of a short ram CAI. On a carburetor, a WAI generally increases FE, on EFI, some cars WAI increases FE, some it decreases, some cars CAI increases FE, some it decreases, YMMV. But as a rule of thumb, CAI increases peak HP/torque, WAI decreases it.

Best thing to do though is slow down, it's an all terrain vehicle not a sports car.
