I like to tell people not to worry so much about acceleration technique* in city driving.

The big, serious MPG gains are to be found by concentrating on the brake pedal - minimizing its use.

That means: don't use any more power than necessary to coast into your next transition (stops, slowdowns, corners, etc.). Coast as much as possible without pissing off other drivers. Every time you use the brake, somewhere a puppy dies. (Oh, and your MPG goes down because you're turning fuel into brake dust & heat.)

Add "avoid idling" to the list and those two techniques will dwarf any possible MPG gains of theoretically perfect acceleration efficiency.

(* unless you're pulse & gliding).

For cruising RPM, the lowest speed in your tallest gear is the safest bet for best MPG. Beyond that, more MPH = less MPG.
