OK, here is a question I have, after filling up your fuel tank and the range on your information center updates what is the range that it reads? When I first bought the truck and the dealership filled it up it read 420 miles as I remember but that kept changing everytime I filled it up now when I fill it up it tells me that my fuel range is 304 miles. With a 25-26 gallon tank it the range should be somewhere around 375 miles I would think. Right now I am averaging about 15.5 MPG according to the information center. Any thoughts on this???????
