Most of the heat that gets into the over plumbed/over cooled oil systems of most of these cars come from the pressure rise in the oil pump itself

Jerry, Can you expain your statement? Firstly, I am well aware of the heat gain when a gas is compressed (and conversely the cooling as it expands). Secondly, I always thought that much of the heat in motor
oil came as it is cooling certain parts of the engine. Why/how does the oil get hotter as it goes through the pump? Is this caused by friction or something else? If you are an engineer, please try to make the explanation using ordinary English so that I don't have to ask for a translation later on.
By the way, I don't think that I have ever seen my oil temp much over 240 F.
Thanks,
Wayne
