This is my first UOA on this vehicle, and my first use of Pennzoil Ultra. The truck currently has 182k miles, and looks and runs great. Most of those miles were on standard M1 or Motorcraft 5W-20 and a Motorcraft FL-400S. I used to do my daily commute in it (moderate highway driving), until I bought my used Jetta TDI last year.
I should point out that this OCI ran 9 months through the bitter cold we had in Wisconsin last winter. And, the filter in this interval was a NAPA Platinum (Wix XP) with the claimed 50% efficiency at 20 microns. I plan to post pics of the dissected filter in the coming weeks.
