Put the cruise on, the needle is always above 30mpg, however its when you touch the gas, it drinks it, once you learn how to drive it, its not that bad. So that means FLOOR it from the lights to get up to speed and put the cruise on, the engine management really is intelligent, it will burn less fuel on the cruise control.
I always laugh as you hear the "new ford focus is up to 32mpg on highways", well my 5.4 v12 is up to 32MPG on highways as well lol although remember i have to use 91 or higher octane gas though (that adds cost). Although i am sure thats why the millage is good.
granted, around town is nasty, i had to find a longer route to work, but has no lights on it so i can cruise at 50kph (live in Canada).
