Such as? If the same volume of oil is being delivered to engine parts by the PD oil pump, then where's the lack of lubrication?
Such as the engine speed. Lower engine speed during startup due to higher viscosity oils can cause slightly more wear during startup. It's covered in one of the links he posted. It also covers why engines wear more during idle, if I remember correctly.
A computer controlled engine doesn't idle at cold start-up any differently with xW-20 through xW-50.
