If the car asks for premium its for a reason (L67 and L47 N*) but the LN3, L27 and L36 don't require high end octane.
In the end, use what is best for your car

L67'* need premium gas or you will experience pre-detonation issues. The guy with the 03 SSEi is ignorant of his new L67....89 is not the recommended fuel and shouldn't be used.
