Rangers arent the best on gas. Your lucky to get the 22 mpg it says on the sticker at the dealership. Only thing you can do is keep your engine and components healthy and clean and keep your foot from trying to put a hole in the floor board. A chip may work idk others will chime in, and a super charger would probably make it worse because theres no way in hell you put a super charger or turbo in a vehicle and not drive like crazy.
