MPG is built in to any given vehicle. The engineers at Toyota or wherever have designed your automobile to certain specs. Nothing you do will change it. i.e. cold air intakes, etc.

I do have one suggestion though that has worked for me:
Whenever you come up to a stoplight (that you know is going to be relatively long) shut off the engine. This works.
