I regret not getting a sample sooner than 1200 miles. I wanted to see what the starting viscosity numbers looked like. At 1200 miles, mine was under a 5w-30, at 9.1 (cSt 100C).
I actually edited my post to reflect that before you quoted me, or at least before you hit the submit button.
Do you have more details on what the factory fill is?
For a 2024, if you get an oil that is WSS-M2C961-A1 compliant, a 5W-30, you'll essentially get a GF-6A oil that has the 7 new tests for timing chain wear and covers the LSPI requirement.
The older SN stuff was typically GF-5, not GF-6.
II checked a few manuals for the years, some are 20w and others are 30w. Here's the currently available manual for a 2018, v3:

Worrying, or getting irritated by their answers, is not worth any more of your time. It's a non issue.
BMW service isn't always great either. I just sent a neighbor to have a key cut, based on his VIN. He shopped it from the various dealers, and BMW of Fairfax was $400 more than BMW of...
IMO, not a big deal.
Not only have prior Coyote engines run on 5w-20, it is also noteworthy that 5w-30 shears down to a 20w fairly quickly. This is pretty well known with so many UOAs out there.
For my 1200 mile 2024 GT, the factory fill is already out of spec for a 5w-30. The viscosity (cSt...
After the update, carplay didn't correctly work. I had bluetooth for Apple Music, but siri sounded weird and it could't pull up the waze map.
It did work on the next power-up.
I'm not too worked up about it. I don't plan on using that oil (motorcraft) and it's the first oil change. The manual does comment about consumption in the first few K miles.
