Great productBy SCOTT, a Verified Buyer from Minnesota on June 15, 2025My Genesis GV70 is turbocharged and requires above standard octane fuel lest the computer backs down the settings and thus performance.

93 Octane Tune SupportBy Whitesheep, a Verified Buyer from PHOENIX, AZ on March 04, 2025The Softronic tune on my Porsche likes 93 octane, but around here it is hard to find anything over 91.

Worked great in my 4 stroke snowmobileBy Moonshine455, a Verified Buyer from Vermont on February 22, 2025I 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 LineYes, I would recommend this to a friend.Was this review helpful?

A treat for my truckBy Mconniff, a Verified Buyer from Slidell, Louisiana on February 10, 2025Occasionally 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 LineYes, I would recommend this to a friend.Was this review helpful?
