Amazon Reviews
"I purposely delayed this review for a few months to give this a chance to sit for a while and see how it does. Dumping it in some gas and saying it works great after a week isn't saying much, right? It's been 3 months since I've added some fuel. I put some in my CanAm Spyder which has aftermarket tuning and requires 91 octane or higher and is pretty finicky about fuel quality. I can easily tell the difference in the way it runs between gas from a top-tier station and a bottom-of-the-barrel station, so I figured this would be a good test for this fuel stabilizer.
After 3 months of sitting in a can that's not completely sealed (so there will be a bit more accelerated breakdown of the fuel due to air exposure) I filled up my Spyder and took it for a spin. It runs just as good as if I'd filled it up with fresh fuel from the station. Very good sign! I'll try some more in a few more months and see how it goes, but so far, this stuff is doing a fantastic job!"

"Used as directed, so far so good. I used with 110 octane race fuel and with typical 87 octane, it preserves fuel better than other products."
~ Kevin
"I bought HappyFuel directly from this website last year. My cars all started and ran much better this year after using HappyFuel. Definitely a premium product. I just bought more HappyFuel from Amazon for this winter."

"My neighbors used this product last year to store their classic cars. They were impressed with the results and their cars ran fantastic so I bought Happy fuel to store my 150 hp Yamaha boat engine for this winter"
~ Jeff
"I own a classic car restoration shop and we use this product in all of our client cars. I personally use this in own classic cars and jet skis as well. Highly recommended. It’s a lot less money to use this product than rebuild a carburetor or flush a gas tank when the gas goes bad."
~ Jim
"This is the perfect solution for those who want to store a generator with gas in the tank ready to go when the power goes out!"

"I used HappyFuel last winter to store my 66 GTO and my pontoon boat. I have to say that there was a huge improvement in both vehicles starting and responsiveness compared to the other stabilizers I’ve used in the past. I’m sold!"
