Well i cant really say. because I changed the tires out at 1000 miles. so the truck wasnt even broken in yet. But now I have 3500 on the truck and it seems like the mileage is going up. I do mostly around town...11 miles to work lots of turns and stop lights. my average right now for the tank is 15.2.
My trip B has since i changed the oil at 1200 miles and the average is 15.0 flat.
Mind you, im talking about an FX4, with a 5.0 not a raptor with the 6.2
