As long as we don't start seeing any tears, all is good.
Media should be strong enough for whatever the manufacturer spec's for flow/bypass/construction/caps/tube/etc.
Understand that 'media shedding' has been an issue with some full synthetic oil filters. I think Donaldson expressed that concern years ago with their ultraweb nanofiber syntec xp media. Microglass 'breaks' and could be abrasive until the filter catches the broken media. Maybe Fram saw the 'cellulose support' as a way to prevent shedding of the synthetic media. Could be an upgrade even if only a 'blend' filter. Pleat spacing on full synth media takes that into account... glass doesn't bend too well. Cellulose can fold and is cheap enough to load up with pleats. Oh well, can't have it all anymore.
Just look how much money M1 made from M1 loyalists selling their 'blend' media M1 filter, at a heavy surcharge compared to other filters. Fram is just getting in on the profit margins too!
