Interesting you mention the UPF48R. GM just sent out a bulletin on using the new UPF63R on the newer V6 engines.
"
Today's engines have very tight tolerances, multiple oil pressure control systems and high flow lubrication system requirements. These requirements will vary based on the specific engine design, so the proper match of oil filter to the engine application is more important than it has ever been in the past.
The High Feature V-6 engines RPO (LGX) and (LGW) have higher oil pump pressure to accommodate engine cam phasing and high-speed bearing requirements. As a result, the oil filter performance was improved to meet this higher oil pressure output.
The new UPF63R oil filter has a thicker outer shell to provide higher burst pressure resistance during cold temperature conditions and greater fatigue strength. Failing to use this filter could result in external oil leaks due to gasket blowout or wrench flute cracks.
Any time an oil filter is changed on one of the above vehicles, it is recommended to use the new and improved filter."
Again, note that nothing is mentioned about it not being able to be used on previous engines, just to make sure to use it on the higher oil pressure system V6 engines.
