yeah TOO high octane rating can harm your engine. For those who uses 91 on an engine designed for 87, don't worry you're fine. 91 is not high enough to do anything but put a dent in your wallet.
Kinda off topic but are there any automotive type groups or events at or near cal poly pomona (besides clubs)?
