I agree with Andrew, forget the additives. Buy the best gas you can and if you have problems take it to a mechanic and he can tune the car for the gas you are using.
You will not notice any performance gains from a bottle of snake oil you put in your gas. If the car is knocking, don't go to the snake oil, go to a mechanic.
