    Evaluation of the AMSOL-BRAND OCTANE BOOSTER
    By  JOE,  a  Verified Buyer  from  NW-CHICAGO SUBURBS  on  December 08, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    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.

    Yes, I would recommend this to a friend.

    Great for our old cars
    By  RONALD,  a  Verified Buyer  from  AIKEN SC  on  March 09, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Worth it
    By  RANDY,  a  Verified Buyer  from  North Carolina  on  January 06, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Additives
    By  Tracy,  a  Verified Buyer  from  Wyoming  on  November 25, 2023
    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
    Bottom Line
    No, I would not recommend this to a friend.

    Must have for Friday Night Lights!
    By  Qualules,  a  Verified Buyer  from  Billings, Montana  on  October 16, 2023
    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.
    Bottom Line
    Yes, I would recommend this to a friend.
