I am very bummed about this and Schaeffer Oil's decision to not move forward with pursuing this spec for my 2022 Ram 6.4.
I called and emailed and received a flat "No" on the phone with a company tech adviser that they were not currently going after that cert. with their Supreme 9000 0w40. The email correspondence was a bit more encouraging, but blamed COVID as the reason for lack of 3rd party testing and any movement on any certifications without calling out this one in particular and with no acknowledgment that MS-A0921 will be there in the future.
Using Pennzoil UP goes against my MOLY upbringing, but having a warranty on a "Fiat" is worth more.
Talk me off a ledge.
