We aren't discussing the secret ingredient at this time, that would be a whole different thread by itself.
We are just discussing what octane our base engine requires. My father and my girlfriend both swear the secret ingredient does work and they came to that conclusion on their own. Example, my girlfriend can go a whole week without gassing up when I put the secret ingredient in. But can't make it the whole week when I haven't had a chance to add it. If anyone's wondering what it is, it was in one of the commercials one of the VCA chapters made for VOI X.
