I would like a suggestion. I have a 1995 F-350 powerstroke, auto overdrive, and it is not getting very good fuel mileage. I average about 14 mpg. I tried a K&N air filter in the factory air box. That did not do anything. I tried the max tuner super chip in the towing and performance modes. No difference at all. I was going to try a different air box, so I took out my stock air box and the new one I was going to try did not fit so I could not try it. But when I was trying to re-install the factory air box It got into a fight with me and was destroyed. So I have now ordered a K&N cold air intake system for it. I have put in a 190 degree thermostat and it has made no difference at all. I am still waiting on the air intake. Does anyone have any suggestions that may help my fuel mileage. I have some friends that get 18-22 mpg depending on how they drive. But no matter how I drive I get the same 12-14 mpg. It also gets the same wen I am pulling a trailer or my fifth wheel camper. Please help if you can. I like my ford but I am considering trading on a dodge to get some fuel mileage. I don't know what else to do....
Thanks.
Thanks.
