    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.

    Does the job
    By  JCharles,  a  Verified Buyer  from  Alaska  on  February 28, 2024
    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
    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.

    Great Stuff, Terrible Bottle
    By  ROBERT,  a  Verified Buyer  from  Florida  on  August 01, 2023
    Like the octane boost although the contents do not drain well norm the bottle. Something in the design of my truck gas filler port prevents the bottle from emptying. No doubt as an antisyphon mechanism.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great boost in power
    By  NICHOLAS,  a  Verified Buyer  from  Pennsylvania   on  July 30, 2023
    I extract ethenol from gas and use this to replenish the octane. Works wonders and much better than 105 or any other brand!
    Bottom Line
    Yes, I would recommend this to a friend.

    Works well
    By  AtlantaAcman,  a  Verified Buyer  from  Atlanta  on  July 05, 2023
    Works like it says, just needs bottles compatible with capless fuel. 1st bottle got stuck so don't even try without funnel of some sort
    Bottom Line
    Yes, I would recommend this to a friend.
