First. Install a 3:70 FD. I never have the trans shift down by the throttle. If I'm on a long climb. I shift manually. Then have a contest with myself as to how many cars can I have pass me before I crest the hill. Drive 55 to 60. Then enjoy the view. Use cruise on the flats. As to Jim K. YES. Average 5 tanks. Fill your tanks with the front higher then the back. Treat your engine to an EFI. For me. I don't really care anymore as to mileage. I'm on a mission to just enjoy beautiful North America.
