Barring that...I am quite sure if you put the AC Delco filter with clean Mobil1 when the DIC says so...you'll be fine and never notice a difference

I started using Pure One oil filters quite a few years ago and noticed the oil stays cleaner longer, and since the Pure Gold filters became available I use them on all my cars.

I've started using the new AC Delco UPF48R..same part # used in the ZR1. I figured if it was good enough for the new ZR1 is would be OK in my lowly LS3...and my Tahoe. Less than $10.00 each. I don't know if the guts are any different than the PF48 but the outer shell is quite a bit thicker.

GM says the internals are the same as the PF48... "The Ultraguard Gold UPF48R filter is black in color, has a thicker exterior shell and can be identified as GM part number 12626224. The internal components are the same in both the UPF48R and the PF48 oil filters. The UPF48R can be used in applications where the PF48 is specified."

GM Ultra Guard UPF48R Oil Filters
12626224 – UPF48R Ultra Guard Oil Filter - $9.85
These filters come in a case of 12. You can purchase just 1 filter if you’d like.
This is the AC Delco Gold Series oil filter that provides more filtering, etc.
Currently used on the 2009 - 2010 Z06 and ZR1 engines. Can be used in place of PF48.

Independant studies have shown Fram to be near the bottom of the list.Good brands from what I remember were the stock AC Delco and Mobil 1 filter. There was another that was rated very high but forgot which one it was.

My questions are: if the internal components are the same in both filters, doesn't that mean the filtering media, too? And what does a 'thicker exterior shell' do?
Thanks for your time.

I appreciate Whisky's question because of what Motorhead quoted from GM, shown above.

"OIL PUMP
The dry sump system uses a dual gerotor oil pump, one rotor for scavenge and one rotor for supply . The pump used on the LS9 produces greater volume and higher system oil pressure to provide adequate oil delivery under all conditions."

The relatively new AMSOIL Ea Oil Filter uses a technology developed by Donaldson to achieve a very good balance of flow vs. filtration. FYI, AMSOIL also carries the well respected Wix Filters (as Wix partnered with Donaldson and AMSOIL to make the AMSOIL filters).
Applicable part numbers:
05-06:
AMSOIL EAO32
Wix 51042
07-10:
AMSOIL EAO50
Wix 57060
