There are many, but it would be more expensive to buy and add them than to simply buy a premium gasoline. Besides, you would need to know which are already present. For example, methanol has an octane number of 120, but it has limited solubility in gas, so you can only add 5-10% depending upon what else is present. For a list you would have to go to a university or college library and try looking up gasoline additives in a catalogue and see what they have.
