I have just returned from a road trip that stretched from NYC to Salem, Massachusetts. The truck performed very well on the highway during the 5+ hours of travel but I wish I could say the same for the gas mileage. I had a maximum of 450+ miles on a full tank but my average mpg stayed at 14.1 the entire trip. If there’s anything I can do to help increase the fuel mileage that would be great. I recently put in a new engine air filter and maybe every 3,500 miles I treat the fuel system with Techron

Just curious, did you reset the dic at fill up? What kind of speeds were you doing?

Does it have a supercharger ?

accelerate like a 90 year granny and keep it at 55 that's about the only thing that will garner you more mpg
