Hello all. Fairly new member here. This is my 2004 Expedition / 4WD / Eddie Bauer Edition, with the 5.4L, and 249,640 miles on it. No mechanical issues and no warning lights. It had a new transmission installed last year along with new tires (10 Ply tires). This is my daily driver to work, about 23 miles each way. As far as what I do with it, I use regular 87 gas, Lucas Upper Cylinder Lubricant every fillup, and a gas treatment about once a month. I also use high mileage synthetic blend oil every 3000 miles. This truck sure seems rock solid. This last winter I drove it halfway across the nation with no issues.
