I don't mean to sidetrack this topic, but the owner'* manual for my '93 SSEi says:
"If the octane is less than 91, you may get a heavy knocking noise when you drive. (In an emergency, you may be able to use lower octane--as low as 87--if heavy knocking does not occur)."
FWIW, I personally know people who use regular or mid-grade fuel in their supercharged cars because of today'* high cost of gas, and nobody has noticed any problems.
Are you saying that "Boom" will occur?
