I just traded a '95 F-150 w/ 6-cylinder & automatic. The best I ever saw on mine was around 17mpg. Ease away from stops gently (as tho you are trying not to crack a egg under the pedal) until you get up to about 20 mph. At other times accelerate gently & as slowly as traffic behind you will allow. I do it on a 2010 Mercury Milan 4-cylinder & it helps get the reading up by 1-2 MPG on a tankful. If you have a manual trans, upshift as soon as you are able without lugging too much. Keep speed at 60 mph or lower. Good luck with your efforts.

To begin, don't accelerate hard, don't brake hard (allowing coasting) and keep your tires inflated to specification.Then keep your care well tuned. This does not have to be expensive. Change the spark plugs, air filter and fuel filter as needed and pour some fuel injector cleaner into the gas tank (when you are about to fill) once maybe twice a year if you've never done it. I myself also add a carbon cleaner once a year (Seafoam). Lastly, don't downshift unless you really need to and travel the routes with the fewest stop lights, though they may be longer in distance.
Acceleration is a big problem with fuel saving. slowly going onto the peddle instead of mashing it helps a lot Tire pressure is a big gain to, make sure your tires are properly inflated. Remove all unnecessary weight from the car. by doing this you create less strain on the motor meaning less gas use. Now under the hood, A clean air filter will save you a lot as well as a good working exhaust allowing for good flowing air through the motor. Making sure your vehicle idle level is set proper can make a big difference. if you idle at 2 thousand RPM's, your burning to much gas. Set it down lower. Also dont let your vehicle idle on a cold morning. Letting the vehicle warm up so you dont have to be cold is a waste of gas. Last of all, drive 55. driving 55mph instead of 65mph may increase your mpg by up to 15% which is a big difference!

I've explored and experimented with this in different vehicles (I'm a mechanic) there are three main strategies, other than maintenance, that can be exercised while driving to improve gas mileage. The first is when accelerating watch your RPMs try to keep them under 2000. anything over that and you should release the gas to allow the car to shift gears. Anything over that is wasting power on RPMs instead of putting it to the road. The second strategy is Avoid idling and coasting. you should have the gas pressed so that you are constantly accelerating at the same rate that friction is decelerating you. allow it accelerate more down hills and less up hills. gaining speed downhill and loose it uphill. The third strategy is to avoid breaking. Don't accelerate so much that it becomes necessary to break to maintain the speed limit. If approaching a red light simply coast to the light and slow down at a constant pace instead of approaching and then breaking when near the light. All of these are based on not wasting energy from a physics perspective. Coasting wastes gas due to the gas requires to idle is being wasted instead of accelerating as well as all the momentum lost during breaking.

I have a 2000 Ford F150, 4x4, and the best I get in town is 16 mpg. On the highway, it gets about 18 mpg. While driving, I coast downhill, and let it ease uphill. I don't mash the gas way down going uphill. The faster the RPM's, the more gas any car or truck will use. So, I rarely drive over 55, even on an Interstate highway.......everything passes me, but I don't care....I am getting better gas milage than doing 60 or 65. I even tried driving with the tailgate down, hoping the wind resistance difference might give better milage, but it didn't! Surprise. Good luck. PS. I have an automatic transmission....don't want another manual!
Mostly, it's accelerating gently, making sure tires are inflated (or a little over the sticker on the door frame), clean air filter. I have a 97 Saturn and get the best mileage at about 60-65 mph, driving at CONSTANT THROTTLE (not constant speed). Yes I've seen 45 mpg on a trip where the window sticker stated 40 mpg highway. Higher speeds cut mpg a LOT. I think it's a fourth power law. Like driving 10% faster increases air drag 40%. Air drag and weight are your enemies. MIght even try narrower tires. Your F150 has a large frontal area and I'm guessing high coefficient of drag. Not a lot you can do there unfortunately.
