I didn't watch anything past the title, however I have bought some of the Amazon oil and so far what I've received was blended by Warren Petroleum, same place that blends SuperTech for Wally World in most western states.
The TBN is similar to SuperTech, at least the stuff I bought from both stores, which is a touch lower than you'd expect from name brand so the add pack isn't as good as a big name oil but still a good value and changed at reasonable intervals should work fine.
