Some vehicles and their oil, just don't operate best with the most expensive - best ingredients oil filter. Case-in-point: GFram Ultras were headaches for many GM models and Korean models for years. Bypass and flow settings needed to be changed.... either at the vehicle factory, or the Fram factory. The best oil filter for our vehicle, could turn out to be inexpensively priced and mediocre construction. Like oil, it's how long to use it, before changing it. It's not always about "it's junk, unless it can go three OCIs or 20K".Money spent is not always the best answer.
Definitely OT, but what does any of that even mean? Are you suggesting that a lower efficiency filter is better than a higher one? What tangible examples exist to support that theory? By and large, the major manufactures of filters perform enough research to ensure their products meet the OEM specifications and will operate as well if not better than the OEM. Obviously, there can and sometimes are exceptions to the rule, but I do not recall ever seeing an example of when a higher efficiency filter caused problems or performed at a level below a lesser efficient one.
