That was from pre-dexos1 Gen2 days, 5 years ago. Re-formulated since then. From: https://www.bobistheoilguy.com/foru...ch-synthetic-spec-sheet-info#Post3845098

Although, it may still have HTHS 3.2, as the current MAG1 5w30 full syn, which has the same dexos1 license number ( D10386HG025 ), has 3.2. Same oil as SuperTech:

Yes, current formula is 3.2.

Reference source for that? I'm probably right about MAG1's data sheet matching SuperTech, although I wonder if the Base Oil Interchange (BOI) rules allows for different viscosity base oils between the two in practice. I don't think BOI allows that anyway, not sure.

Per email from Warren Distribution. SuperTech Syn motor oils and syn gear oil are the same as Mag1.

Amazon Basics is most likely the same as the other two. I was just at Warren D. If i could only take pictures.... They make lots of other brands too ive never seen or heard of.
