Off my escalade w 180,xxx on it, filter was in use for approx 5k miles, oil was magnatec 10w30 syn blend. The anti drain worked well as oil spilled out when cutting open the can. Media was good, no tears. Replaced w parts master filter and 5 qts PYB 10w30 & a qt of Penz 5w20 HM
I quit using this PF61. I was getting cold startup chatter and my PF61s had no ADBV. I wonder if AC Delco added a ADBV to the PF 61 in the last couple years.
