It's up to you. Maybe you can get an octane tester to find out if there really is an effect, first... as you can't always trust what's on the website.

Note, ha... that you're also not sure how much of a boost it will give you, even if it's legit. A lot of the octane boosters on the market don't give you much of a boost per bottle.

I normally dislike adding additives, as you're never really sure if they're safe, but if the EPA approval number checks out (I suppose you could check it online), they should be relatively harmless. Good luck!
