a 4cyl is too small of an engine for a ranger you need a v6 for that heavy of a vehicle. but have the exhuast checked may be plugged up. could have brakes hanging, also have a diagnostic run on the computer advance auto does it for free and gives you a print out.

plugged fuel filter or clogged catalytic convertor.
check the air pressure in the tires for a start. It may that you have a higher ratio rear end like a 3.73 to 1. Then it will be tough to improve a lot. the only other thing is to slow down and improve your driving habits. Think economy, before speed. Good luck.
normally those trucks do pretty good on fuel,id have the computer scanned and see if anything else came up that might explain why its not getting good mileage,if the plugs are gaped right in it and all else is ok ,then it should do fairly good on fuel,have the scan done on it auto zone will do this for free,and then you might know more about it,right now it could be anything wrong with it,good luck hope this helps.
Hate to tell you this, but those Ford Rangers ALWAYS got lousy gas mileage. :( It might be worth your while (not to mention the FORTUNE you'll save on gas)- if you trade that old gas guzzler in.
