regarding fuel filter, it has been tested that even in the west there are impurities in the gasoline. one is 'coffee filter test' where you attach the paper coffee filter to the end of the bottle while pouring the fuel in, and apparently there are black residues on the filter. maybe this is one of the main culprit of fuel injectors getting clogged.
i am afraid that there are many wrong things about ethanol. it is wise not to use it if one has the choice. but as in diet, one has to make up one's mind what is really healthy... with ethanol situation it is similar when vegetable oil (polyunsaturated fat) was introduced in the name of reducing cholesterol. all the propaganda made naive folk believe that it is healthy, even though it is one of the most toxic substances you can put into your body. ethanol thing is just conspiracy created by some manipulative companies to make more money. why would one voluntarily want to put that crap into the tank is beyond me...: but is your bike.
"The peak flame temperature of ethanol is 1,920 °C (3,488 °F), while the the peak temperature of gasoline is 1,026 °C (1878.8 °F). Ethanol burn hotter meaning car engines run hotter.
One of the bad things that happens when ethanol used as a fuel is that car mileage will actually decrease. The New York Times stated that E10 gasoline, which is the gas used in America, actually provides 2-3 miles per gallon less than gasoline. E85 is a flex-fuel with 85% ethanol loses 7-8 miles per gallon.
Compounding the problem, the use of ethanol causes gummed-up fuel systems, damaged tanks and phase separation caused by stray moisture infiltrating fuel systems. Automakers have filed a lawsuit against the EPA's decision to make E15 (gasoline with 15 percent alcohol) legal for all cars after 2007. They argue that, among other problems, the blend could damage the engine."
