There are zero 10w-30 oils that meet Dexos, it is not part of the spec.

I don't make any decisions based on Project Farm videos. His methodology is usually sound but they are just one-off experiments, not producing any conclusive evidence. If he repeated the exact same experiment hundreds of times, then we would have something useful. They are entertaining and interesting, and they help my understanding of OPE (outdoor power equipment).
I agree, his videos are entertaining and have some usefulness, but is not an end all proof of how good an oil is in an engine.

They say mag 1 is warrens flagship product so why would I go to Walmart to pay the same price for something that isn't?

An interesting note, Mag1 5w-30 and Supertech 5w-30 share the exact same Dexos license number (D10386HG025), as well as 21 other oils.
Same for Mag1 and Supertech 0w-20, they share the same Dexos license as 16 other oils (D10394HG025).
Interestingly, Supertech 5w-20 has a unique Dexos license (D13002IL025).
Now does having the same Dexos license mean it is the exact same product, no idea, but does give one a way to help make a decision.
But again, as I said before, if it makes you feel better to use a more expensive oil, that is fine, it does not make a difference to me, but saying one product is "inferior" because of personal beliefs does not help others.
