First question, has anyone put 100+ octane in there car? And what did you notice?

Second question, Has anyone tried grounding there knock sensor?

I have searched but could find no answers, if there are please point me in the right direction, Thanks!!

 

The higher the octane rating in the gas the less "explosive" it is. (Octane makes it smoooth burning) Unless you're getting knock, running more octane won't do a thing for you....
