Higher HTHS protects against wear. It is a documented fact.
If the vehicle is always driven in normal service, there are no mechanical defects such as leaky injector or coolant leaks into the crankcase, no over heats. The 0w20 is fine. But the additional barrier of viscosity adds a layer of protection.
