Why would Mobil 1 5w30 be factory fill when
GM6094M is the recommendation?
GM dealer filled oil with conventional 5W30 vs synthetic, should i worry?

Not sure why Mobil is saying that but I work in the plant that built that truck and it was Mobil 1. The eventually cancelled Mobil 1 as factory fill somewhere around 2009-10 (dexos replaced all certs) so perhaps Mobil lumped all years together. However - when you see their recommendations - they are all syn oils except the last one.
Maybe you will sleep better with 0w30 and run it long enough to offset the cost delta. It’s going to have a good base stock to start with.
-25C is nowhere near too cold for any 5W rated oil with or without a block heater.
And ignore the goofy “cold flow videos”. It’s about the winter rating.
If the OP gets to -40 actual, I would also consider 0w30, with lowest pour point readily available. Or if -40 is an outlier, make sure it's plugged in when it gets that cold.

Every time I have to go into a Chevrolet Stealership I worry!
Would that be API CK ?
Shell Rotella T6 5W30 multi-vehicle is a full synthetic rated API CK-4 and SN, not saying it’s exactly that oil, but they would be typical specs (or SP instead of SN).

back to main topic, any ideas on what the oil is exactly?
You mean you forgot it in the two hours since you last used that identity?
And btw posting under more than one user name is against forum rules.

I meant to say that one account was logged into my phone and I forgot the pw to be able to log it onto my laptop. That’s why I made a new account. Thanks for the info. I’ll let mods know from my phone to delete the Apollo account

You got any other user names you wanna tell us about?
Never heard of SPI and the only CA I know is the original diesel API spec ”CA” but that is from about the 1940’s with CB in the 50’s and CC class oil from the 60’s (or thereabouts). These are a completely obsolete oil classes. We are up to API CK now with CH being the oldest I have seen on the shelves.
With API (American Petroleum Institute) you had Cx for diesel Compression ignition engines, and Sx for gasoline Spark ignition engines. Plus there are some new FA diesel oils that are less viscous and more Fuel efficient. Maybe he said “FA” as these are usually 5W30’s or 10W30’s.
Conventional means a mineral (non-synthetic) oil, but sometimes they are a synblend (semi-synthetic) to meet the modern API specs.
You also have the Euro ACEA specs, but these are unlikely as a bulk fill in America.
