First, I'll assume that by "Bomb", you don't mean that it will blow your motor up?

Sorry, couldn't resist. Zinc is generally a boundry lubricant, used to protect when the hydro properties of the oil are no longer present: shock loading, cold starts etc.
If you do some searching, you'll find that even Amsoil (which I do not use)has more zinc and phospherous than this one you're mentioning. And then my question is this: Why would you use a "conventional racing oil" when there are so many fine synthetics out there doing a better job?
