After going to 35s on my 4dr with automatic trans, my MPG dropped to about 14.4 MPG on my daily, all side roads, commute. I re-geared from 3.73 to 5.13 and it went up to 14.9 MPG. (Speedometer has been re calibrated for tire size and confirmed by GPS with each change)

Today I decided to see how big an impact driving style could have. I made sure I never exceeded 2000 RPM on my commute today. I still drove about the same speed, but I accelerated much slower from lights and stop signs. It really wasn't that much different, just took about twice as long to reach top speed.

The results : 18.4 MPG

Post up with your best MPG on your modified rig. Show those mad driving skills!!!
Post your 2dr or 4dr, trans, gears, tire size and best MPG on a drive of 10+miles.

(I know someone is going to say "It's a Jeep, why do you care about mileage". Save It. This post isn't to debate that topic. I just want to know what results you can get)

I just started doing exactly what you did. Will post up my numbers later when I go through a tank or two. Prior to driving more"sensible", I was averaging about 13.6 on my 35's with 4.10's. Just brutal!

Last tank I averaged 16.8mpg with 35s, 4.10s and a 6spd. Shifting at 1500rpm around town. But city driving here is city driving, light after light, after light. So it isn't too bad. Still messing with the highway speed/rpm, I'm either going downhill or uphill here, nothing flat!

On the way back from Moab a few weeks ago, I drove from Pagosa Springs, CO to San Jon, NM (355 miles) on one tank of gas which averaged out to 17.15 MPG. That is the best I have ever done. I think the Colorado gas is better or something because here in Houston I can barely drive 300 miles on a tank. I have 35s with 5:13 gears and auto trans. I was driving 65 - 70 MPH and it is mostly down hill the whole way so maybe that is how I did it. It was kinda like being in the twilight zone... I kept thinking I should pull over and get gas but I kept looking at my gauge and I didn't need to get gas.
