what kind of gas mileage could be expected from a 1990 5.0L 302CI mustang?
Buy a honda?? :laugh:What would be the cheapest modifications i could make to enhance gas mileage?
Agreed. Some things may help a little, other things will hinder it. Start with a nice fresh tune up and go from there. These cars are around 20 years old so mileage may vary! I get about 22 hwy, 18-19 around town....however, I didn't buy it for the economic aspect!! :winksNothing you're going to do is going to significantly increase gas mileage.
