Mine was QDF on the order sheet and came with Michelin Primacy LTX, not the Energy Saver. Haven’t scanned the QR code yet.

Entirely possible.  GM just added an XFE package to the 2019 truck, and they may have added the Energy Saver in addition to the Primacy, or replaced the Primacy with the Energy Saver all together.  This could be just like the QAE 20" tire where there is two options for one RPO code, and it depends on the build of the truck.

I am having trouble finding exactly what oil to purchase for my new 6.2 Denali first oil change.

 

I do see 8 quarts of oil, but unsure of weight required.

 

Anything unusual about oil change on these trucks?

Any Dexos-1 Gen2 approved 0w20 will be plenty good and is the GM recommendation. Don’t need to turn this into another oil thread...I use Mobil 1, but anything meeting that Dexos Gen2 standard is fine.
