1997 f150 2wd, How to help Gas Mileage??
I have a 1997 f150, 4.6 V8 2wd with 77,000 miles on it. I got it from a old man that didnt use it to much. It has 31 inch tires on it and ive heard alot of things i can do to improve gas mileage but what is the most efficient one? A Cold Air Intake? What should i do?
