Gas Mileage
Brand new to the site as of this date. I recently bought a 96 F-150 that appears like it has never seen a winter. I am from the north so things get rusty quickly. My question is what is the best gas mileage I can expect with this truck. It has 59K miles and a 4.9L 5sp. with a 3.55 Checked it one time and got a shocking 11.25 miles per gallon. Very disappointing for the way it runs. I used to get close to 20 in my 78 F-150 with the 4 sp. OD. Is this normal or is something wrong. I also have a minor exhaust manifold leak but I don't think that is the cause. Any help would be greatly appreciated. Thanks

I do not have a lead foot and take it easy. I live in the country so it is almost all highway type driving. I don't lug the engine and shift to soon nor I wind the gears either. I do have a cap but it is cab high and also it is 2wd. 8ft bed and a regular cab if it helps.
I rarely go over 60. The tailpipe is a light grey so it is not running to rich.

A major tune-up was done by a Ford dealer less than 14K miles ago. It seems to run to good for needing a tune-up, do you really think that might be the problem? Does the computor store up codes if prior problems were sensed? I don't or haven't had a check engine light since I have had it. I have only had it for going on 3 months and have not put 1K on it yet.
One thing that occured to me is with the slight exhaust leak could a knock senser be retarding my timing?

Just got back from Crisfield Md. (Live near Baltimore). Truck has NEVER gotten over 14.5 before in any condition/load/speed.
Drove down Friday averaged 62mph/AC ON. 14.77 mpg
Drove back sunday evening, same roads....NO AC averaged 53mph....15.6mpg
Used the front tank for both ways.
