No.... If you're claiming that one oil that meets the same specs as the rest is better than they are, then the burden of proof lies on YOU.That’s called an “Appeal to Ignorance Fallacy”
It works both ways. Until proven otherwise, oil is not oil.
Just because we can't prove that your oil isn't better doesn't make it actually true. That burden of proof lies on you to show it to be so.
It's "Russell's Teapot" (https://en.wikipedia.org/wiki/Russell's_teapot) just for oil.
