I have 5 full years of data on my truck that I have tracked every fill-up and miles when done. Both before and after deletes; the fuel mileage before was a yearly average of 11.59 MPG and after I deleted the average is now between 13.87 and 14.17 MPG. I tow a 5er so this is the only time the truck is on the highway the rest of the time, it is in local traffic. I use yearly averages because this takes out the variable of filling up the truck and road conditions. See truck in my signature for mods.
