You mean besides the torn ones repeatedly documented here on Bitog and elsewhere:
Guess it all has to do with the meaning of “NOTHING” being wrong with them.Fl820s fail - Ford Truck Enthusiasts Forums
Oil & Lubrication - Fl820s fail - I bought my 2008 F350 may of last year and changed the oil soon after I got it. Used a Motorcraft FL820s. Only use the truck to tow the camper and haul thing home from Lowes and stuff like that. Only put 2500 miles on the oil and filter. Just changed the oil...www.ford-trucks.com
Wow, I'm totally convinced now! The cited thread has 10 posts. TEN. No actual problems, just one person was upset about the design. Let me summarize that particular thread.
Dude bought a 2008 Truck of unknown maintenance in 2017, 9 years old. He changed the oil (no idea if he did it correctly or used the correct weight or dino or synthetic) then drove it 2500 miles including towing and hauling. Then he changed out the 820S. The filter media is black as coal. That's a hint that there's possibly something else going on with that 10 year old truck, unrelated to the filter.
When I change out syntethic oil after 3000 miles, in my well maintained 4Runner that I know the history of, it's still carmel colored. Dino oil is black. When I change out oils from cars with unknown motors and maintenance, it's often black... we have NO idea of the history of that 10 year old truck.
Color me unpersuaded....
