Finding 100 percent gasoline is hard and getting harder all the time. Efforts are afoot to turn the 10 percent ethanol blend into a 15 percent blend.
What is ethanol? Why is it used? Is it any good? Does it really harm engines? So what's the flap about ethanol?
Ethanol (CH3CH2OH) is not-aged alcohol. The only difference between ethanol and a shot of your favorite at the bar is filtering, aging and added flavors. That's it. The same corn that produces alcohol also produces moonshine. The factories that produce ethanol for addition into motor fuels are just giant stills.
