Hello George; I'm "Confused" as to "WHAT" properties an oil would contain that would disqualiy useage on the street.

My thinking would be obviously counter-intuitive meaning, if a certain oil can withstand the hardships of RACING!!!...How would LESS demands of the oil in a street engine negate the beneficial properties of the oil that are so advantageous on the race track???!!!...Mark
