The pinging noise that you hear is detonation occuring in one or more of the cylinders. The dealer suggested to move to a higher octane inorder to prevent this because the higher the octane the higher the prevention of Detonation.
The Probable cause of the pinging, would be that you refilled with a bad batch of gasoline. Premium should be used in this vehicle no matter what. Due to the clearances of the heads and valves in the motor. And also due to the material used to make the cylinder heads, if severe detonation occures then the valves could be damaged.
