Correct me if I'm wrong please.
The car actively aims to heat the oil to 100c, this allows it to evaporate any water in the oil.
Also JB4 starts working at 90c so you want it to be higher
Also this is just a guess but the viscosity of the oil will be at its warm rating past 100c and is able to better coat the engine.
