slowed down to 45 mph once for a good stretch, i was almost out of gas, and the mileage meter said i was getting 30mpg.

i tried playing with the ECO option enabled yesterday to see if i could drive and trigger "ECO-on" in the display.

i failed. keeping the light on would increase my fuel usage sitting at many more lights. i had to accelerate so slowly, and i think my shift points need to be tweaked somehow to deal with the lame local 30, 35, 40 speed limits/traffic speed. the auto kept seeking at a cruising speed, kicking itself out of ECO.

driving my jeep my way is definitely worth the 14-15mpg i get for DD in mostly city traffic, and 17-18 on road trips.

I average about 18 around town and 22+ on highway trips by keeping the tach around 2,100 to 2,300 rpms. I have a 6-speed with 3.73s and am running 265/75/16 BFG Rugged Trail TAs. As others have said the key is to keep the RPMs near 2k.

Are you constantly using Cruise control? Most people have no idea how much they actually slow down and speed up on the highways. I've gotten 2-3 mpg more than what's rated on all my vehicles by simply using cruise control on long trips. This of course is'nt always practical, even on the highway, just try to do it as much as you can if you're that worried about it.

You have an '11. Look at the tach. There is a green line on the tach inside of the hash marks. That is the ECO activation zone. With the auto you have to have O/D enabled. Cancelling it wil cancel the ECO on. The green zone is 1000 rpm to about 2000 rpm solid, then truns into hash marks at 2250 rpm. I posted in another thread about ECO on parameters. I used it religiously starting at 1350 miles on the odometer. I managed the get my mileage to 23 and some change. 416.9 miles on 17.669 gallons. The mpg readout started at 12.8 and is now at 13.8 You are definitely not in the power band's sweet spot staying at or below 2000 rpm. But the mpg numbers are there. I have gone back to driving around town with O/D off. I will see what mileage is on the next fill up.

The 2011. The 2007 has 37's on it. I do not even worry about mpg in that one.

He cant go those slow speeds of 45 he would be cut off and crashed into. cruise control is not really an option either on the LIE unless its way out east on LI. i get about 15-16 mpg on the LIE.

I have a 08 2DR JK, auto, 33's and a 1.75" BB. With my superchips tuner I get appx 20-23mpg depending on how much HW and how much city I do.
