The circus is coming to town.
Instead of elephants and trapeze artists, there will be motorcyclists throttling their Harleys and antique cars circling the US Capitol. They have more than spectacle in mind. They will be protesting the existence of a fuel called E15, gasoline blended with 15% ethanol.
The fuel is sold in only a handful of stations nationwide, but is touted by ethanol backers as the safety valve that will allow more renewables to be blended with gasoline. Currently, most light vehicle engines only carry a warranty for use with a 10% ethanol blend–E10. But declining gasoline demand, combined with rising biofuel blending mandates means the country will hit a “blend wall” sometime in 2014.
