Best octane fuel for 2004 ford Crown Victoria?

The 2004 Ford Crown Victoria's owner's manual recommends using regular unleaded gasoline with an octane rating of 87. Using a higher octane fuel (like 89 or 91) won't provide any performance benefit and is simply a waste of money for this vehicle. The engine is not designed to take advantage of the higher octane.
