OEMs recommend their own stuff because at least they know what is put on the vehicle, and the real message is they don't want you using some cheap oil filter with a bad nitrile ADBV (startup noise if its leaky) and/or a high resistance filter media.
Fram Ultra is actually about the best in the category with a silicone ADBV, and the filter media is low resistance. Not to mention it also filters better and doesn't develop holes in the media like some do. And holds twice the dirt as paper media oil filters. .....
GM and Subaru do break from Fram's design approach with high bypass valve threshold pressure. That seems to be unique to their engines. There was another thread around here recently where we tried to estimate the differential pressure requirements of full glass/resin fiber media vs. paper media, and we suspect the paper oil filters have a tougher time handling high flow when cold & viscous without high differential pressure, but that's another story.
