Anyone using motorcraft engine oil?
Coming up on the first oil Change in my "new" 96 powerstroke with 266,000 miles. I'm putting a royal purple filter on it because from my research they have actually made a better filter to sell rather than taking one off somebody's assembly line, painting it a different color, and calling it "better". Now for the oil. Schafers puts out a great product, and I would like to use their 5w40 synthetic. Problem is I'd have to drive 45 minutes to get it. Has anyone out there used the motorcraft synthetic oil? Have you had any analysis done? I am really interested to find out how it tested for breakdown. I use the motorcraft Dino oil in my 6.9 , because its fairly cheap and that old pickup burns it faster than I can change it, but even after 5,000 miles in that old 6.9 the motorcraft oil is still cleanish looking. The rotella I used before would have been black as coal. So in conclusion, anyone using motorcraft 5w40 in an obs? Good results or bad?
