well holy crap.now i am not sure. there is not much info on the actual web site.
if it does take 8oz then you get 1 octane per ounce added to 1 gallon of gas. thats expensive, i wonder where the other site got its info? one has to be wrong.
wonder how much it takes to keep the valve seats lubed up?

are there any other brands that boost octane? this was just one i came across.
