Because there are more posts of torn ones than any other filter.Amazing, no other filter stirs up more activity than an 820S.
I don’t think there are any “issues” anyone on this forum would post about. That doesn’t mean it’s “fine” either. More particles in the oil equal more wear, but unless engines are torn down and the wear measured there’s no way anyone will see a difference via a UOA or some other nonsense.on cut open filters yet no engine issues that derive from all those torn filters...seems to me if the product was as poor as is reported on this Forum that there would be at least some issues with engines that use the filter...
on the other side of the issue, there are still so many mechanics or people intimately involved with repairing at least Ford F150 engines for their other issues that recommend the FL820S filter for the engines they work on...
Bill
And they are comparing the detailed measurements from those engines to what? Tell me please.but you seem to be making my point...mechanics who DO tear down engines using the FL820S aren not reporting issues stemming from use of the FL820S filter...
THIS FORUM is the one that reports issues with the filter after cutting them open...but I don't read or hear of issues elsewhere...
I don't have much of a dog in this hunt...I own 1 vehicle that uses this filter and have only owned it 2 years (5 oil changes and uses) and I don't care what name is on the filter I use...what I DO hunt down is the recommendations of those that have FAR more experience with something than I do when making my decision...it surprised me since many of the vehicle Forums I belong to recommend this filter or that part...on the F150 Forum it is almost universally recommended to use the FL820S filter...that is a pool of thousands of owners recommending the same filter.
It is only when I come here to this Forum that I see the FL820S is a poor filter...and the evidence is what the filter looks like after it has been cut open...yet NO ONE can show ANY evidence, and I have asked repeatedly on this Forum for such evidence of the filter causing an issue with the engine using it...
that's my only point and we can back and forth with anecdotal evidence of what might happen but when the average mileage is well over 100K miles with many more over 2 and 3K miles without engine failures or issues with the engine due to poor oil filtering while using the FL820S it makes me suspect who has the best information...
good luck with your choice...

I was a Ford technician for many years and I do not use the FL820s on my vehicles. I've cut them open myself and seen the tears. Why would I want to run a filter....that does not filter?but you seem to be making my point...mechanics who DO tear down engines using the FL820S aren not reporting issues stemming from use of the FL820S filter...

ha ha! 5 pages 'so far' would appear to confirm that fact. 'I' find the threads entertaining reading for their similarity in discussion and participants. In my observation this sub-forum, the topic filter anecdotes have had more than their share of ugly media and tears.Amazing, no other filter stirs up more activity than an 820S.
I've always been a "practice risk mitigation" type of guy if there is a choice to do so. Not using oil filters that have been shown to tear quite frequently is one of those risk mitiagtion choices that everyone has.ZeeOsix,
You tried!
FWIW - I'm with you, I will not use a filter with a history of tearing. That being said I never had a tear with Purolator/Motocraft cartridge filters and I used those from '06 - '18 in my '06 4 cyl Fusion.
So after seeing dozens of torn 820S filters posted in this forum you're still OK with using them because no other place reports any issues? I have a hard time believing that of all the 820S filters cut open across the country, that BITOG is the only chat board or social media outlet that reports the torn filters.I don't have much of a dog in this hunt...I own 1 vehicle that uses this filter and have only owned it 2 years (5 oil changes and uses) and I don't care what name is on the filter I use...what I DO hunt down is the recommendations of those that have FAR more experience with something than I do when making my decision...it surprised me since many of the vehicle Forums I belong to recommend this filter or that part...on the F150 Forum it is almost universally recommended to use the FL820S filter...that is a pool of thousands of owners recommending the same filter.

Guess what else doesn’t work when the media has a hole in it? The ADBV, oil can seep right past it & drain back to the sump. The tensioner seals on my ‘03 MGM 4.6 2V are shot at 135K, to the point that I have to crank it for 20 seconds with the throttle wide open (to cut off fuel) before starting it if it sits more than 8 hours. A torn media filter would make that issue even worse than the XG2 that’s on it now.I was a Ford technician for many years and I do not use the FL820s on my vehicles. I've cut them open myself and seen the tears. Why would I want to run a filter....that does not filter?
Can I prove that pieces of filter media caused many of the problems on the 5.4 3v? No. The most common culprit we were seeing was blown tensioner seals causing a loss of oil pressure to the top end.
Didn't know the size changed. Would like to see a pic of it next to the newer smaller ones.I do miss the fl820s . The very old one was a bit taller too . I still have the original one . When I heard they making change to fl820s and make them little shorter . I went to Walmart right away and found 1 way back in the corner . I still kept it brand news til this day . Mabe 10 years ago ..

Been in this forum too dam long since 08 with my forgotten accounthttps://www.crownvic.net/ubbthreads/ubbthreads.php?ubb=showflat&Number=1859752
It's been over a decade since size change.
Thanks. I am sure I used the older design before but never noticed the change. I was also surprised at the 20 micron efficiency rating.https://www.crownvic.net/ubbthreads/ubbthreads.php?ubb=showflat&Number=1859752

I figured that might be the next observation when link posted. Like many topics covered many times. That spec appears to be a generic 'at minimum' spec. (OEM OF generally keep efficiency as proprietary info.) Amsoil tested (2011) some OEM filters using ISO 4548-12 including topic 820S, results showed 93.7% at 20um. Chart has been posted many times this subforum, it was compared Amsoil which tested 98.7 at 20um. Can't think of any reason for Amsoil to pump up another manufacturer's OF numbers.......I was also surprised at the 20 micron efficiency rating.
