I question their last statement, but they are trying to sell the stuff right? It is a classic "might" claim. "might", "might not".

Well, it could happen. If the vehicle ECM in question is programmed to advance timing beyond specification untill knock is sensed. Very few cars do this. The vast majority start at factory spec and retard timing whenever knock happens.
