It would be interesting to run a datalog while running 87 to see if there actually is any.. i'm sure someone on here has done that.

There probably is one someplace yes. I only bring it up as a possible not as a given. I would hope that the ECU would prevent any issues and under normal driving it would almost be guaranteed that it would. Hard driving on the other hand could be a bit of a gamble to trust that it would all the time. They require high octane for a reason and I don't think I would want to trust the ECU to protect my engine for a prolonged period. That isn't even taking the retarded timing and resulting loss of power into the equation.
