Anyone know what's up with these different PF64 filters? The one on the right is what I've been using. Just ordered a new batch for my 2018 Z51 and they are all like the one on the left. Looking at the bottom they are clearly different and the part numbers are also different (left is 25206966, right is 12696048)
ACDelco puts their name on them, I'm sure they're fine. Probably a different supplier for them by the looks of some of the writing on the top of package.
I agree w/ the OP, those are 2 radically different filters. All this crap over the last 4 years that I have owned my Stingray makes me want to go to Mobil1, or Wix or? I was looking for a number that ended in 595. My file shows that 595# was good one as of 12/2023, 6 months ago. Now that seems gone. Pretty sure also that info on this forum was saying 048 was not a good # to use. Looking right now at an online GM parts seller they list 2 filters. One called a Gold is a PF64F # ending in 865. But the illustration shows a plain blue PF64. They also list a UPF64R w/ a 50% gold label that says UltraGuard Gold and a # ending in 847. This ACDelco info is such a mess, and changes so often it is disgusting. I have one more 595 on hand but who knows what info we will have when I need another filter.
Just got the same ones / Purchased from Amazon/Amazon (seller). Seem legit as construction looks to match with the nylon core-etc. Same box too/etc. Would seem if you got yours from Rock Auto and mine from Amazon and they appear to match, they must be a new rev/mfg of AC Delco.

Technology does change from 10 years ago. I am sure we don't want to use filters made with 1990's material. It's a good thing when newer technologies are introduces, normally.
My guess is that GM has a new application they need a filter for, and then build a new filter for it, which also meets the specs of the prior applications. This way, one filter will suffice for multiple applications.
There are other car companies who handle updates a LOT more sanely. Using the #s from Ventor instead of this; 12640445 12696048 12706595 25206377 25206966
we would have 12640445
12640445A
12640445B
12640445C
12640445D
So when you are used to buying say, the B version, and go to the store and see the C version, you would immediately know it is the new version of what you have been using. If it works better for computer systems to have the same # of characters in all the numbers, just start w/ the A number. Just think, the dozens of oil filter threads in the 4 years I have been on this forum wouldn't need to exist. Seems simple to me.

It's actually very simple higher number means newer version
Weird / different PF64 filter
