I just ran two tanks of strait ULSC #2 through my 6.7. I [Always] dump in a 16 oz. jug of Power Service Diesel Kleen at each fill-up.... but thought it was time to bring the ratio back to maybe a little closer to what Ford recommends.
Observations without any additive: A little down on power when towing.. and a +/- 2 MPG drop in overall MPG's (according to the lie-o'meter).
With an additive: Jus' plain starts, runs and pulls better, in All respects.
