I found this on the internet. Unlike many other internet articles, this one is written in a way that makes it seem like it's correct. Their bottom line is that for most engines, running lower octane will not harm the engine, but the increase in fuel usage will approximately equal the fuel savings if you are supposed to run on a higher octane but only run the lower one.

There was also an exposé on Canadian TV before Christmas on a show called marketplace.
