What octane does it boost it to?? If I put 93 in my tank and a bottle of your octane boost. What octane would I be at?

Question, is your Octane Booster Ethanol based? I specifically use non-Ethanol based fuels, I' ve been using Octane Boost but it doesn't list if it's Ethanol or non-Ethanol. Thanks

Used it on my Mitsubishi Evo X with every fill up the past 2 weeks and enjoying the extra boost!!!

This the first time, I using this product to my bike 110cc Honda, Earlier I was used product STP, but STP has not full fill their performance. Now Gumout Octane Booster has fullfill as they told. I happy with this product, Good Acceleration, Super Power improvement, I was really feel difference. Better than the STP Octane Booster. Thanks and keep it up.

i have used this for a year. when my car got older it slowed now it runs like new

I bought this because my car has been acting sorta sluggy lately I am very glad I did it kicked the slug right out of there.

I bought this for my special tuned yamaha R1 and put this in to see if it would help anything and so far it has boosted my horsepower by 6.22 and it's makes it just run smoother than normal less vibration noise lets me get up to speed a lot faster.

Have owned five Corvettes over a period of 16 years (a '95 LT1, an '02 Z06, a '96 LT4, another '02 Z06, and now an '08 LS3), and have used a bottle of this Gumout product in each car at EVERY fill-up. I highly recommend it.
