I am curious, There are a lot of different oil filters out there from Fram, Wix, Baldwin, K & N, Napa Gold, etc. I think that Amsoil uses either Wix or Baldwin (I can't remember which) for the 6.5. I assume that Fram is the cheapest least effective. Where do the others rank in effectiveness? I remember seeing the tests done at the place on fuel additives and air filters but I never saw anything on the oil filters.
