Walmart Supertech is made by the same company that makes Mag 1. Very possibly exactly the same fluid.
Very possible.
However, Mag 1 oil is indeed the cheap stuff sold to shops that do cheap oil changes and I know a number of guys using Walmart Type F in good transmissions. Not Top Sportsman level stuff. More like Stockers and Super Stockers.
Personally, I would not be likely to use it. Mostly because I try to avoid Walmart.

If the results don't match the theory, change the theory.
