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.

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.
I have a motor with 10:1 compression with a total advance of 35 degrees at 3000 rpm’s . The only problem I had was when I shut motor down it would diesel or run on with the first bottle of AMSOIL octane booster it has stopped
Good stuff
Bottom Line
Yes, I would recommend this to a friend.
