I've been using Amsoil lubricants for almost 10 years. I started using their octane boost a few years ago in my 2011 Raptor when off roading and it give me that extra power when i need it most.
Bottom Line
Yes, I would recommend this to a friend.

After receiving this advertised product performance additive, I tried it. I am happy to say it actually provided substantial performance; you could feel it. In my opinion, the product price could be better. It is a little overpriced and should cost customers less, thus causing better social awareness of this good product.
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.

octane boost

I run 12.5 compression on a 448 cu NA hemi and 93 pump gas
when I know there will be some real hard pulls I always add one bottle
of octane boost to 10 gallons so far no knock no hemi tick no timing retard
OBTW I also run Amsoil 60 weight !!
Our 1959 and 1964 Cadillac Fleetwoods need a little boost from 89 octane non-ethanol gas from Circle K. This gives the octane boost our cars were used to when they were built.
I own the last generation Audi V8 Biturbo engine. I don't trust octane ratings at the pump and use this product as protection.
Bottom Line
Yes, I would recommend this to a friend.

Worth it

2020 WRX stage 2 93 tune. Started adding a bottle of this to my tank at my tuners request (he runs it in his personal 2019 WRX) and it really made a noticeable difference in everyday driving. Engine is running smoother now, idle through whole rpm range, not getting any mis or really “hesitation” that it had been getting off straight 93 pump gas. AF learn was out of spec: +/- 18-20%: in half a tank running this product those numbers have dialed in and are staying under +/- 8% where they should. Highly recommend this product if you’re running a similar set up! I have noticed throttle response is more accurate, it feels like the car is running at its best, and the car just feels “happier,” I guess would be the best way to explain it.
I got the octane boost to give it a little bit more horsepower but I don't put that much into it. Cause I think it's just for racing so use it your own description
I use this in my 2012 Cadillac CTS-V, 6.2L, Supercharged Motor. Friday nights here are big for Street Racing. I'm a 64 y.o., gearhead, so when I pull up in the Caddy, I get some raised eyebrows. I always use, non-E-85, premium fuel and dump a bottle of the go-juice in the tank at the beginning of the evening. It is noticeable in the seat of the pants feel from the stock 556 h.p. LSA.
We race everything from hopped up diesel trucks (yes, this IS Montana!), to 5.0 Mustangs to JDM projects. I'm not saying I beat the 'stangs all the time, but enough of the time to get some notice and respect.
