The difference in burning 87 over 93 is performance. The engines have knock sensors and when you burn 87 and the engine starts predetonation (knock, because the fuel isn't stable enough not to in a high compression engine) the knock sensors will retard the timing until it stops. That retarding of the timing will decrease performance. Thats it.
