Or is the whole zinc snake oil based on an old wives tale?

Why would you think that a modern, higher revving, hotter running engine would NOT need something in the oil to replace the zinc?

Or that the modern oils are not backwards compatible? Anybody read a jug for API standards lately? What is the earliest spec they promise to meet? SC? SD? SE?
