Is your car a 6MT or auto and what year is it? What oil are you using in the motor?
Check your brakes to make sure there's no dragging and that your parking brake is completely disengaging. You could also have worn wheel bearings adding drag to your rolling efficiency. The front wheel bearings aren't known to be terribly durable on these cars.

Try cleaning yer MAF. It's not likely gonna cause that big of a drop, but it might help a little for the time being.

In theory you'd get more mpg because you'd have better airflow at any given throttle position, but yer ecu will just adjust for the extra air by dumping extra fuel. You would have more power (negligible) at, for example, 50% throttle which would allow you to take your throttle position back to ~49% and that WOULD in theory give you better mpg, but good luck trying to meter that.
