Been driving the same 160 mile rountrip (not all flat ground) to the airport and back at 70-72 mph numerous times since I have had the truck. Two people on board and no A/C on. Computer always shows low 22 mpg with hand calculation usually mid 21's. Went to pickup wife at airport the other day and had a little extra time to spare so set cruise control on 65 mph and with A/C on - so one pasasenger going up, but two coming back. I could not believe my eyes, computer said 27.7 and hand calculation was 27.3 mpg. Filled and re-filled at same gas pump. I am blown away - how can that little drop in speed make that much difference ??
