You can certainly use any 0w-20 Dexos1gen2 that you like.
I ran Mobil 1 0w-20 AFE for the first 2 changes, then went to Amsoil 0w-20 Sig. Series and will stick to this.
I am running the revised Fram XG10575 with 22 psi bypass (been out for over a year now) so all stock should be 22 psi. You can tell by looking at the bypass valve. White 22 psi, black is the old one 12 psi). Whichever filter make sure it has the 22 psi bypass. Wix/Napa Gold is a reputable and fairly priced filter with the correct bypass.
Pennzoil Platinum 0w-20 would be great as it is Dex1gen2. However, as you mentioned the Pennzoil Ultra Platinum in NOT Dex1gen2.
If I was buying off the shelf and wanted to stay frugal, in spec. and great protection I believe I would go with QSUD 0w-20.
FWIW, my engine was quiet and smooth on M1 0w-20 as well as Amsoil SS 0w-20 with no oil consumption.
The ACDelco PF63e is an ecore design that has been fine, just not one of my top picks.
By the way the Amsoil SS 0w-20 isn't a Dex1gen2 license oil, but I still like it!
I bought and installed that Fram XG10575 filter. Curious, what do you mean about the 22 PSI bypass? I typically am seeing roughly 30 PSI indicated on the gauges when idleling at a light, so does that mean I'm not getting any filtration?
The Bypass valve only opens if there is 22PSI of pressure drop across the filter media, typically happens during cold starts during the winter up here in the north or if the filter somehow becomes clogged, with the oil up to temp you could have 75PSI oil pressure and the bypass would still be closed if the filter is not clogged.
