Re: 6.4 Powerstroke fuel mileage
Sorry guys, but I'm going to need some help here. I've had mine since early March and have just over 4,000 miles on it. Changed the oil at 3,000 miles and have yet to tow anything. Just returned from a trip (virtually all highway miles) of 686.9 miles and burned 46.8 gallons. Squeezed every last ounce possible into the tank immediately before and after getting on and off the highway. Set the cruise on 75 and left it there. Where I went to school that works out to 14.677 mpg. Since this is my first post on this site, I certainly don't want to be confrontational, but anyone posting here saying they are getting 22, 20 or even 16 - 18 mpg on the highway I must question. Either there are some tall stories being told here or something is wrong with my truck. I truly would like to know which it is. Please enlighten me.
