I've been following the whole tearing FL-820S stories here for quiet sometime. I just cut open 11 of the filters that were used on my 2002 GT, 2008 Ranger 4.0, and my uncles F150 4.6.
My Mustang and my Dad's Ranger have always ran Mobil 1 5W30. My uncle uses whatever on sale.
Of 11 filters, zero were torn. The Ranger is ran year round so its seen quiet a few very cold start. The Mustang gets started a few times over winter but ran hard in summer. My uncles F150 has a tough life...
I also cut open a wack of AC Delco Ecores off my Silverado and FIL's Traverse and Impala 3.6. No issues either.
Other than making a massive mess, and dropping a pile of filters and oil off at the recycler, I didn't really accomplish much.
The FL-820S's go back years and years too. Nothing torn. Waved as per normal. They were still holding lots of oil.
