Another great UOA on my 2004 F-150. The numbers speak for themselves.
Mileage was about 80% highway, 20% in town with no short trips (we live in a rural area so even "city driving" requires a highway trip to get there). The filter used in this interval was a Wix 51516.
For anyone interested in the history, the first UOA on this report from 6-15-14 was PU (the old pre-GTL) 5w-20. The other two are Amsoil XL. Very similar add packs.
Current fill is the same Amsoil XL 5w-20 with a Fram XG3600.
