The average fuel economy of my vehicles is mpg.
Reducing my top cruising highway speed from
mph to
mph will improve my fuel economy by 1% per mph reduction over 60 mph.
Reducing all rapid acceleration and braking can improve non-highway fuel economy by 3%. Together these actions will improve my fuel economy to 0 miles per gallon, saving 0 gallons per year.
Assumptions
