You’re not measuring wear. Only in your imagination.could give dozens of examples of high mileage and thin oils, all of which are available here. But I think then the next excuse comes from you. If oils are released for 0w20, then there is no more wear than with a sae 40, for example. These are practical experiences. Whoever says thicker is always better at wear and tear who just lives in yesterday and not in the present.
Again, if you only understood some basic physics that would help.
You were gone there for a while. Did you go on a vacation?
