I would say Amsoil, many great UOA's, it doesn't get modified often like other oils do(like green/gold and other changing oils).
My reasoning is this: It has many great UOA's, I like the fact that it doesn't get modified like other oils do(stable oil from a stable ethical company), it seems to be better according to the comments of others in terms of engine noise compared to some other oils. It seems to perform well with nice extended UOA's even without bypass filters where I'd want one. If it goes out of grade it goes up one, which I have no problem with.
However if the green GC was not modified and the company seemed less shady, or it wasn't a factor that I might not be able to find it in the future if I were to get some now, it would be the perfect oil. It really depends on how you interpret the question.
Hypothetical situation time
---------------------------
I'll call the perfect oil P-Oil: To me I would need it to circulate well in the cold. Protect well in extreme heat, which makes a Group 4 and beyond oil a P-Oil.
The next step is that it needs to perform well on an extended drain with better wear than other oils, hence Perfect oil.
It needs to leave nothing behind and it needs to be able to suspend enough to clean a decent amount of what was left behind from other changes.
It should have some form of cleaning and antioxidation additives, something that works like LC that is already inside the oil, I think it's a great idea, no?
P-Oil would need to be found in more stores than some of these localized oils, such as GC in Autozone.
When I get to thinking what is the best oil I always think of UOA's, extended drains, and a clean engine, and I expect a PAO oil or better.
