First sample on my new (to me) 04 Expedition. Dealer MC 5w-20 every 5000-6000 since new, until I bought it, and used PP. It was probably a quart low when drained, but I wanted to see how the UOA came out without adding makeup oil, and mainly to see if I can run 10k intervals. (Easier to remember, plus the filter is kind of a pain to get to compared to other vehicles I own...)
