    93 Octane Tune Support
    By  Whitesheep,  a  Verified Buyer  from  PHOENIX, AZ  on  March 04, 2025
    The Softronic tune on my Porsche likes 93 octane, but around here it is hard to find anything over 91. This gets the job done and then some with one bottle per tank.
    Bottom Line
    Yes, I would recommend this to a friend.

    Worked great in my 4 stroke snowmobile
    By  Moonshine455,  a  Verified Buyer  from  Vermont  on  February 22, 2025
    I added about 1.5 ounce of Octane Boost to about 10 gallons of last year's gas when I pulled my 4 stroke snowmobile out of storage. It had previously been dosed with about 4 oz of gas preservative/stabilized added when it went into storage. It ran great on my first ride.
    Bottom Line
    Yes, I would recommend this to a friend.

    A treat for my truck
    By  Mconniff,  a  Verified Buyer  from  Slidell, Louisiana  on  February 10, 2025
    Occasionally I will give my truck a treat, every couple of months I'll put a tank of 93 octane, where I normally put mid-grade I like to think that using the higher octane will keep things a bit cleaner. When I do this I will try to put one of these "Octane Boost" into the tank with the 93. I can feel a difference when I accelerate and knowing that I am using quality fluids from AMSOil I know my little truck (2016 Ram Power Wagon) is well taken care of.
    Bottom Line
    Yes, I would recommend this to a friend.

    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.
