I read an article in some magazine several years ago that found the best mileage (with a stick shift) was to accelerate with a fairly heavy foot, but to short shift. (ie: let off the gas and shift lower in the RPM range than you would for a given throttle setting)
They explained it like this: piston engines are more efficient the wider the throttle is, and by accelerating vigorously to cruising speed, you can then close the throttle to granny position quicker.
I looked (briefly) on Dr. Google for the article, but came up with this instead:

one of the letters talks about this method.
