You want mileage, ditch weight.. I dont mean by dropping a four popper in it, thats gay. Even ruining a 350 car with a 6 would be hella gay. Replace the rear glass with lexan, strip the interior, replace the doors with fiberglass and replace the hood with fiberglass. If you dont wanna do all that, just stop going out to eat, or sell it and use the money to buy a Honda Insight.
