Without making any further assumptions, I decided to ask if the typical properties for their 0W-30 matches those listed in the 2021 Product Catalog. The answer is yes.

I think it's safe to say that the rest of the properties for the other viscosities are valid as well.
At this point I don't think we should fear anything or make any negative assumptions. It looks to me as Red Line Oil is overhauling and modernizing their formulations to bring them in line with today's specifications and demands. Many small displacement T-GDI engines specify 0W-20, and some performance models specify 0W-30. You'll notice that viscosities such as 5W-30, 0W-40, etc. are still API SN. I assume they're updating them as well, but not to the extent of API SP compatible engine oils.
Time and UOAs will tell, to some extent, how these new formulations hold up.
