Out of curiosity, what are you 97-06 wranglers getting? I average 14.7 in the city but my commute is only 7 miles one way. I don't really idle my jeep either like if the food line is long and I don't idle for warm up. Just wondering where I compare to others. Fully dressed, winch, bumpers, spare and such with 33s and 4.56 gears.
