CT5-V Blackwing PF64 Oil Filter NLA?

[TR-6060]

As I look to order some Supercar 0W-40 and oil filters, it seems like the PF64 may be NLA like the PF63 mentioned in the thread below.

Anyone using the PF63 instead of PF64 on a CT5 Blackwing?

The potential end of the PF64 is also mentioned in a recent BITOG article and Rockauto no longer has a listing for the PF64.

While some sites may still show some PF64 stock, it looks like it is being replaced by the PF64A (black can) and PF64B (white can) variants. Both the A and B replacements currently have listings on Rockauto and all three filters show up in the ACDelco online catalog and Cadillac parts site for the CT5-V Blackwing.

The current GM CT5-V Blackwing service manual spec for the filter is still the PF64. Does anyone know for sure if the PF64 is end-of-line and if Cadillac has moved to the PF64A or PF64B in their service centers?

Three weeks ago I bought a few pf64 filters through speedway motors. Still blue pf64 can. Only thing different from previous orders was that these are in sealed bags and not boxes, and they are the most recent updated gm part number.
