This is a direct quote from the Owners Manual:
"The engine is designed to operate using premium unleaded gasoline with an octane rating of 91 AKI or higher. If premium unleaed gasoline is not available, regular unleaded gasoline with an octane rating of 87 AKI or higher may be temporarily used. For optimum engine performance and driveability, it is recommended that you use premium grade unleaded gasoline."

According to two different Subaru salesmen, using 87 octane will NOT damage your engine. (In fact when my Subaru dealer sold me my Tribeca I am pretty sure that they filled my tank with 87 octane. ) The one thing that they did stress was that I would get overall better performance and mileage with Premium.
