i averaged 26.4 mpg on a trip from kankakee to dwight IL, reseting my dope scope after filling up and ending it when i pulled into the parking lot of where i was going, that was after new plugs, filter, oil , coils and adjusted air pressure.
guess you zj boys don't know much about a more efficient and productive engine
or how to light foot it for a whole trip. i touched the brakes once, and that was when i pulled into the parking lot at my destination. 55mph the whole way was a buzz kill but i kept it groovy baby ;0) a little hendrix through the infinities to boot. it was like 1974 all over again.
