I was averaging 18.9 until i changed both my fuel filters, now i'm getting 15.2. don't know why.

Re-install the Fuel Filters.. Check for good Air Tight seals around all gaskets and O rings ? Air intrusion in to the fuel system is not a Good thing.

I run a jug of Power Service, Diesel Kleen (Grey jug/Walmart) in my 6.7.. in every tank. Now & then I run without it.. just because. Ford recommends [their brand] but they want to much $ for it.
