    Anyone into performance should really consider this product!
    By  PETE,  a  Verified Buyer  from  NH  on  October 13, 2024
    5 stars for the engineer(s) that developed this concoction! It increases the "Smiles Per Mile", as well as the throttle response in my LS2 powered 5th Gen. GTO. I add a bottle of Octane Boost every track day I attend, and whenever I want to impress friends that occasionally get to ride in my hotrod!
    Bottom Line
    Yes, I would recommend this to a friend.

    Want a Lil More Pep in Your Step
    By  ROBERTO,  a  Verified Buyer  from  New York  on  October 13, 2024
    I used this product 1st with my Caddy ATS and when I I tell you she really hauled booty when I would use it, I’m being dead serious. Octane Boost does the same for my CTS-V so until I get my flex fuel kit I’ll be turning to Octane Boost when I want to move a little quicker.
    Bottom Line
    Yes, I would recommend this to a friend.
