Ethyl alcohol, or ethanol, is a grain alcohol that in the US is derived from corn. America is the world’s largest producer of ethanol (Brazil is the second), but despite our thirst for beer, most of that alcohol is going into our gas tanks, not down our gullets. Why is it in our gas? According to Congress and the EPA (Environmental Protection Agency), corn juice is blended into our gasoline to reduce our dependence on foreign oil and to help cut tailpipe emissions. The politics, economics, and environmental impact of ethanol are all subject to debate, but we’ll steer clear of that controversy and instead stick to the facts and focus on how ethanol affects your motorcycle and thus you.
