Simple; one word--CAFE. There is no other reason to reduce viscosity to those levels except in the quest to eek out every single drop of MPG from the engine. There is always a trade of economy versus longevity else high HP engines would run any viscosity, but they do not, do they? At any rate, this has been beaten to death and I have no desire to do it all over again.
