I too get 20 pretty consistently with a corrected speedo gear on 33's/3.31 with my 5.3/4L60E. Thats cruising steady at 60-65mph. If i go much over that the mileage drops quickly and I have keep it out of overdrive to have the RPM's in the correct range.

I get 13-14 in my F150 Supercrew. I DD (weather permitting) my CJ on 35s and 3.54 gears, 200+ miles a week to work topless ,because it gets a lot better gas mileage. I never actually figured out the numbers, but my wallet tells me it's way better.

4.2, MC2100, Team Rush, 35 Grabbers and 3.54 gears, 3 speed automatic. That's a 50/50 mix of city and highway, cruising at 60 mph at 2,100 rpm.
