14 -15mpg highway on my 85 stock (31" tires) (with many carb and exhaust leaks, am fixing),
30-35mpg on my 83 bj60 275r15 tires, can't wait to put larger legs on, 5spd with overdrive(the od in 5th brings the revs down from 2200 to 1600 at 75mph, the 3b loves sitting at 1600- 1700 (i'm not sure about the diff gearing) think I need to rebuild my od though, they don't last long without extra cooling as i found out.
