93 octane in stock engine

I have always heard that if you don't have a high compression engine, that there is no point in running anything more than regular 87 octane unleaded fuel. I know some people that run a tank of 93 octane occationally to "clean out the engine", but it seems to me this is not required (other than to get some of the additives like fuel injector cleaner, etc that some companies put in their premium fuel). Anyone have thoughts on this?
