If you knew the specified efficiency rating of the FL-820S, you might change your mind. An efficiency of 80% @ 20 microns is nothing to get too excited over IMO. There are many other good filters out there that will do much better than that.
You know I'm aware of the rating, but the FL-820S is the standard choice on my son's 05 Explorer. The OLM on the Explorer is consistent @ ~5k.
I/we changed his oil and filter over the holidays and changed out his filter 820S with another 820S. I cut it open today to check it out. The FL 820S is a very solidly built filter all the way around. The efficiency rating that Ford/MC states baffles me a bit because to look at it's construction one wouldn't think it's accurate. That said, no matter the rating, with regular 5k OCI's using the 820S, I expect his engine will go a long way. And, for ~$3.70 at Wally it's priced right. I'll try and save it until I get a camera with which to post pics.
The Xtended Guard at more than twice the price would likely be a better choice for extended OCI's than the MC.
