In service for 7 1/2 months, since July of last year, using bulk Valvoline 5W20, on my '03 Grand Marquis (with a weak thermostat the whole time). It had a small startup rattle a couple times, so I replaced it with a CQ Blue, I'll give it a couple thousand more miles, & then change the oil (leaving the filter on). ADBV still soft, but it didn't have a lot of oil in it when I took it off. I'm beginning to think silicone ADBVs are the way to go on ANY filter not mounted base up (on the 4.6 it's basically on its side). Definitely resembles the Casite filters I used a while back.
