Yesterday on his local(DC Metro area)radio show a couple callers asked about synthetic and dino oil. His answers were kinda blanket statements if you ask me. He states one of the major advantages of synthetic oil is it's roughly 700 times stronger then dino in shear strength/stability(ability to stay in the bearings under extreme pressure he was saying). I've heard him mention these number(700 times more shear strength)a bunch of times but is it true? He also stated less engine wear on a cold start due to synthetics being more "slippier".Able to move throught the engine more easily.Less wear at normal operating temperature due to easier flow with a synthetic also. The guy asked if it mattered what brand of snythetic he used,response was something like "no,any one of the major brands is fine". Another guy called in asking about upping to a 10W40 over a 10W30 due to a slight consumption over a 5K OCI(car had over 270K with M1).He answer basically said that he was sacrificing flow to all the internals over a small oil consumption that was normal in new motors. What say you guys?
