Dr. Haas is s dipshit. He has been destroyed on Bob Is The Oil Guy because of his outrageous claims. He is the guy who promotes running 0-5 weight in everything.
However....I like to read his stuff mainly because it promotes thought.....but I have dismissed him as a educated "guesser".....what is your question about his old oil temp ramblings?

His point about wear at startup is correct but thinning the oil isnt correct. if startup wear is the leaading cause of engine failure why not put in an electric oil pump that turns on with the key so you could have oil flow before the engine is turning. but obviously manufacturers have discovered the startup issue isnt relevant. on the issue of oil temperature, the temperature of oil has to be I think at least 195 at the coolest, this is to evaporate any moisture that accumulates in the oil and help to burn off any hydrocarbon build up also.so yes cooling the oil is good but under the 195 mark is pointless and counterproductive for your engine.

That is why I run a 180* T-stat in the winter to make sure the oil heats up good and switch in the 160* in the summer

After my H/C/I my car would hit 230* with the A/C on in traffic so I put on a dual 1" core radiator and a 160* T-stat to keep it cool. Fans are programed to come on at 185* all the time. It will still hit 185 in the summer with the 160* stat when city driving sometimes so i still think it heats up enough.

From what I have read the oil will generally run about 20* hotter than the coolant with the ideal temperature in the 195*-220* range.
