All else being equal, more Revolutions Per Minute = more gasoline (think about it, it takes gasoline to fire in the combustion chamber to drive the crankshaft). Generally the best gas mileage, aside from going downhill when injectors are turned off and rolling force takes over, is the fastest speed possible at the lowest RPM's possible.

I think you'd have to have a significant number of fill-ups and tests before it could be reliably assumed to work. I know everyone wants to increase gas mileage with gas pushing 4 bucks, but this doesn't sound promising to me. Not trying to be a killjoy, just realistic.

Ever ridden a bike with more then one gear?
