I have to say I was suprised when I saw they had added it to the premium fuel. I had been running 91 octane in the Vette when I went out to fuel up not to long ago and saw the 93 octane on the pump. High octane is good right?

Not necessarily... I'd use whatever is recommended for your application. Too much octane can make the motor run as inefficient as too little. Octane is only an anti knock agent. Too much = bad, too little = bad.
