I've googled this to death and can't find 1 article to support using higher octane on a well maintained engine if all that's called for is 87 octane.
The cost savings over years (and gallons) of gas purchases would buy you a new engine if you stick to regular.

Or.....you could save money by running premium because your premium economy is 4mpg better than your regular economy and my engine is pretty damn spotless inside too. But I'm desmogged, tweaked, and my compression ratio is greater than stock.
