You are absolutely free to make your own determination if an oil is worth using or worth changing for another, If you are satisfied with any one particular oil then that is fine, no issues.
No, I am not using the Castrol in my BMW because that's the same as the branded BMW oil. I couldn't care less who makes the oil for BMW, all I care about are the approvals and certifications. I used to use Mobil 1 0W-40 but when they dropped Longlife-01 approval I started buying Castrol instead. The containers of Castrol 0W-40 at my local Walmart still are the LL-01 type so I'm continuing to buy that, but if it no longer carries the approval I'll probably just buy anything that has Porsche A40 approval since that is a very demanding specification.
And I have not "researched out" the best oil, how would I do that? I'm not capable of determining that an oil is "stout" by a VOA or UOA like some on here are seemingly able to do, nor do I really know whether my M60 engine likes an oil either. I also don't know whether your criteria of "like" is an acceptable substitute for a manufacturer's approval. All I know is that when an oil carries a particular certification or approval that means the oil has a performance level equal to or better than what the manufacturer specifies.
Off topic, first your signature said you were from Texas and Global, then just Texas and now just "US". Did you move?
