This was in use for around 5,000 miles on my 1995 Acura Integra LS that I sold earlier this year. This filter sat in the garage all winter. The oil used was Havoline Synthetic 5w30 (API SM rated c. 2006). There were some below freezing temperatures during this OCI. No torn pleats, just a bit wavy. The filter was still full of oil so the ADBV was working fine and still pliable, but I found a tear in the ADBV when I looked at it more closely. This was not caused by my cutter and it appears to have been there during the run... I'm just glad it did not compromise the seal and it didn't cause any dry starts that I could tell.
