You should go on fuelly.com and look at some 2012 owners' entries to get an idea what you should expect. Some of these posters above may be giving you false hope. From my own car and looking at some fuelly users' data, I wouldn't expect any more than a 3-4 mpg improvement overall after the engine breaks in. I hope you do better than that, and if you do please come back and tell us.
Here are some sample graphs of users who started out in the low 20's and pretty much remained there after a few months and a few thousand miles. By the way, fuelly also shows that any other late model compact (Corolla, Civic, Elantra, etc.) can stay in low 20's mpgs depending on driving habits, so this isn't limited to the Focus.
