How's your mileage changed ?

Took first road trip after had gears changed from 3.08's to 4.88's.
Checked mileage before and after, before it was rightat 16.5 mpg.
Now I can set the cruise and in 6th ,just let the Jeep work,MUCH BETTER
Now it is 14.86 mpg which I dont think is too bad . Still running 32's for now.

All I know is that I left with little more than 3/4 of a tank and I got back and it was well under 1/4 tank...with the gas light coming on very shortly. Think I drove around 215 miles total....probably (85% highway) and will tops off....thinking I was getting only about 16MPG. Probably cost me a good $30 to drive in gas..... :P

Oh well, now I know why it is not my DD.

mine is only a 2.8 (not 3.8), so the actual consuption won't be relevant (now about 10.5l/100km - diesel), I did noticed though that somehow the consumption got better (2 months ago the average was 12l/100km), with or without CC (it doesn't make any difference on same road conditions).
