My brother is seeking a oil filter that needs changed as infrequently as possible. This is for his 3.5 EcoBoost F150 Platinum. Ford couldn't competently place the oil filter I guess, the end result of a filter change is oil dripping off the bottom of the truck at various locations for days. I've got him using Xtras for 2x 9k intervals. Not good enough. I saw MicroGreen is claiming 30k. There is AMSOil EaO's. Both would get him 3x. The other option I know of is a filter relocation kits, which I am not really a fan of.
