My 2004 (new body style, not a heritage) just rolled over 100,000 miles. Going to drop all the fluids for a change out. It has the 4.6 V-8, 2 wheel drive short box regular cab. It is an XLT with all the popular options. Still runs, drives, just like a new one. Also going to do a complete tune up, and fuel filter. So tell me about your F-150. How many miles? What about your oci, and of course, what do you use for it's life blood?
