This is the method I use on my Buick to net almost 40mpg, its very odd and seems to only occur on automatic vehicles, MT it doesn't happen.

Its reverse of DWL in that you allow the car to slow (very slightly) on flat or inclines and for me was much more effective than DWL. I also would accellerate when needed on flat ground or down inclines if needed and still DWL'd as much as I could up the incline but needless to say on an auto you can't DWL up long hills the whole way.

My foot would get tired because the motions were so small, but I could maintain speed barely for tremendous distances while getting about 10mpg better FE on the guage

Something to try on an auto I guess. It doesn't really work on my dodge because the thing slows down like it has a parachute behind it.
