You have asked a question for which you will get as many different opinions are there are people who answer - we all have our pet theories, and most of us have stories to back up our bias. You already know mine, so I won't repeat myself and start that whole argument again. I think most of us will agree that if your engine is in top notch condition, it will run great on any type oil you put in it. If it is tired, or worn out to the point where the oil pressure is so low that the lifters clack when the engine is hot, the engine needs to be rebuilt, and no type of oil is going to make that problem disappear.
