I was turned on to this product by a fellow motorcycling friend who said he'd gotten great results with it, so I bought a bottle of it and tried it. Wow! The engine seemed to run smoother, I had better throttle response, and I could even run my bike on a lower octane fuel. I soon figured out that this additive would actually SAVE me money in the long run, so I turned around and bought a whole GALLON of it! My wife and I now both run it in our bikes, and when we store them this winter we will be putting this in our tanks to stabilize the fuel (this product is said to keep gas fresh up to 36 months!). We even put some in our snowblower's tank and IT runs better, too! Give it a shot--I'm sure glad WE did!

I have been using Ethanol Equalizer for almost 2 years now, I use it in all my engines.On my motorcycle, some bad fuel had caused phase separation and contaminated my fuel injection system, after using a 4oz. bottle at 1/2oq. per 5gal. it ran better than it ever had! I used to look through the throttle body's at the intake valves and see oily carbon, Ethanol Equalizer has left them shiny clean. On my dirt bike it boosts octane and has stopped the detonation I had experienced, and I use it in all my engines in storage as an economical stabilizer. I love this stuff!!

Works great. I use this in my motorcycles for winterization. I have never had a problem with the fuel while I have been using this. Great product.
