fuel mileage

I am a new member to FTE and I have a question about fuel mileage. I bought a used 2001 F-350 Crew Cab, Long bed, 4-wheel drive with 20k miles on it last spring. In the summer I was getting around 12-13mpg in the city and 14-16mpg on the highway at 70-75 mph. Now I am only getting aroung 10 mpg in the city and 13-14 mpg on the highway. After reading some threads I notice that my mileage is pretty low compared to others. I was wondering what I can do to get my mileage up or is there something wrong with my truck. I know winter blend fuel brings down the mileage, that explains the drop in the winter, but even the summer time mileage seems low. I have changed the air filter to a K&N, change the fuel filter, but nothing has helped. I installed a Superchips programmer and that didn't do anything either. I would say that my driving habits are normal. What can I do?, I was thinking about tank mods, and maybe trying amsoil.

Yes this is my first diesel, but what do you mean by learning to drive again? Do you see a big difference in mileage with winter blend fuel in this area?

Driving a dlesel is different than driving a gasser. They are like women at the K-mart and there is a sale. You just dont rush them. Go easy on the fuel pedal and you will see how it wants to run --- yo will have to get the "feel" for it. The fuel up here has a winter blend to "alleviate" gelling but it still happens. I add power service to the tank to slow down the gelling problem.

Thanks Bill,

I will have to try driving a little easier. Its hard though, sometimes I just want to floor it and blow those gasers out of the water. I did just get back from Philly this weekend and using Power Service and driving 70-75 mph, I got just over 15 mpg. Not to bad I guess. How do you like you ATS flip controller? What kind of improvements did you see?

My friends around where I live tell me they don't get much better mileage than myself. I guess it really depends on how you drive. Did you notice any difference after you did the tank mods. I was considering that also.
