Excuse my haphazard post if this has already by discussed, but I felt that it would be something us guys with older trucks would care about. That being the introduction of CK-4 oil replacing CJ-4. Apparently its an issue for Ford whereby they claim accelerated wear in their engines with this new oil.
Anyone have any experience or knowledge of what this new CK-4 classification is all about.....or why it was introduced? I dont care other than I dont want my "older" engine to wear out for sake of environmentalism.
