Eastwood Fuel Guard - Ethanol Treatment is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Us eit in my Motorcycle I bought this awhile back to try. During one of Eastwoods' Sales. And have been using it in my 2010 Yamaha Majesty With every fill-up. So far I have not had any issues with the Ethanol. Which most "Riders" are aware of. Motorcycles and Ethanol don't get along too well.

About Eastwood Fuel Guard - Ethanol Treatment

Got a Carburetor?
Today’s automotive fuels have as much as 10% Ethanol blended in your gasoline. While this is good for domestic farmers and our environment, it is harmful to your carbureted engine.
What is Ethanol?
Ethanol, also known as Ethyl-alcohol C2H5OH, is a domestically produced fuel additive made from renewable resources such as corn, grains and even potatoes. Ethanol is good for our agricultural economy and helps us reduce our dependency on foreign petroleum products.
What is Phase-Separation?
Ethanol and water readily dissolve within each other. When the two reach their maximum saturation point, the water separates and is released into the fuel. The higher the ambient temperature, the sooner phase separation occurs. Phase separation can occur in as little as 30 days.
