--- Quote from: Jeffy on September 28, 2013, 12:14:52 AM ---So here's an update on my Jeep. With the A/C and driving from SF to Bakersfield on hwy 99 I made 20.6 mpg driving at the speed limit or slightly above. From Bakersfield to Oakhurst, it was again around 20 mpg. Then driving up hwy 41 which takes you from a few hundred ft to over 5000 ft in a short time (35mph most of the time), to the Yosemite Valley then out on 120 back to I580 I was getting around 16.6-17 mpg. Still with the A/C on. Well, until the pump decided not to work anymore and lock up. But in any case, that's not too bad for a lifted Jeep running 33's and 4.56's at 70-75 mph. I also had the rear packed with tools, water, and a lot of other things. So, not too bad. It was only a little bit more tiring then driving a car.

That's actually quite good. I am lucky to get 15 mpg out of mine!

on the hwy I am getting 18-20 doing 70mph. 2.5L with 31" tires. I do have a cracked exhaust manifold and a patched mid pipe that leaks like a sieve. Hopefully after I get that fixed i will see some better mpg

Mine is still about 15mpg city/17 mpg highway with 4:10 gears and 31" MTs.
My tires are holding up decently and it's going to be awhile before wear forces me to change them. But if I moved up to some skinny 33s at some point, I'd probably do 4:88s and I wouldn't be surprised if my mileage numbers stayed around the same as now.
I've been keeping the top off year around and using a cab-cover for when it's parked -- topless driving admittedly probably doesn't help with the aerodynamics.

i'm between 14.5 and 15.5 if i drive normal, stepping on it gets me to 13s
jfrabat:
LAst time I checked, I was back to 14 mpg's, which is REALLy good for my rig (the best I have gotten out of her EVER was 15, and that was with no lift, no winch, no aftermarket bumpers and 31's!).
