Proper maintainance and a light foot are probably the best & cheapest way to optimum fuel economy

run some fuel injector cleaner through the system to improve the mist pattern, as well as change your plugs... Bosch Platinums increased my fuel mileage by a bit...

A cold air intake, headers and a high flow exhaust will help also.
