The wear curve vs. HT/HS has been posted here many times. It shows that no oil prevents all wear, but the curve shows an inflection at about 2.6. However, this is not representative of all operating conditions for all engines. High miles is not necessarily indicative of low wear without further inspection.So you should never make the mistake of making sae20 oils bad or saying about the ever-increasing wear. I think the future will provide further evidence by seeing high mileage.
Some people like to present the facts as something else but I think most on here see through it. They have a motivation for doing so that is generally not technical nor is it based on those facts.
