Ed Wallace, a local automotive expert, has a 5 hour show every Saturday morning on the radio in the DFW area called "Wheels." When asked if you need high-octane fuel in modern cars, his standard answer is, "I have never used anything but 87 octane in any car I've owned since 1999." He maintains any car sold in America since 1999 will run on 87 octane just fine without any damage whatsoever. He does say that ethanol does do damage to our engines and that the government is going to increase the percentage of ethanol that may be used in our fuels. This will result in shorter lifespans for our engines.
