This is the start of that link you posted Jim. I just had to read it from the beginning. I don't remember which chapter you specifically linked, but I read that and then realized that there was more.
The only reservation that I have is that Bob sounds like he knows what he is talking about, and his flow vs viscosity vs psi stuff is a valid technical point....somehow I just can't bring myself to use a 5w- 30 or a 0w- 30 oil .... but like he says at the beginning chapter, forget what you think you know about motor oils. I find that after reading all of it that yes I held the common misconceptions because I grew up with natural base stock oils. Synthetics do not behave at all like natural base stock oils.
