[QUOTE="Zeb, post: 1537536, member: 30304"] I use Schaeffer’s 5w40 in both our 17 6.7’s. One has 50,000 miles and the other 92,000 miles. Motorcraft filters. It might be overkill, but both those trucks tow all the time, and I change oil and filter every 5,000 miles, fuel filters (Motorcraft) every 10,000 miles. [/QUOTE]
