Changes to AC Delco PF-61

[Loobed]

AC Delco PF-61 filter now replaces the older PF-59. The PF-59 required an anti-drian back valve, thats why the PF-61 now have them. AC Delco decided to consolidate some of their filters to reduce inventory and production costs. I dont think an ADBV will hurt anything in the PF-61 unless you are running the oil backwards through the filter.

Thanks for the info on that. There's been some discussion here at BITOG that the number of filter models overall in the industry will be reduced. Unless I stock up on old inventory, I expect the Baldwin & STP line to go the same route - by adding the ADBV.

AC Delco introduces the next generation of Duraguard® oil filters. This advanced filter technology allows the filter to function better while being lighter and more easily recycled. The oil filter redesign will be a rolling change with no price impact. An improved nylon core provides more open area in the core, yielding more filtering area for improved flow in a smaller canister, while maintaining the same capacity as the larger canister. Increased efficiency, higher collapse strength, and higher burst strength are the result of a roll seam design. The redesigned concave base plate allows for the accommodation of the combination relief and anti-drain back valve, while incorporating a raised threaded flange. Four new filter sizes cover the redesigned part numbers.
