    According to Consumer Reports, "ethanol isn’t as energy-dense as regular gasoline so you will see worse fuel economy with E15 gas.” [67] In March 2009, a lobbying group from the ethanol industry, Growth Energy, formally requested the U.S. Environmental Protection Agency (EPA) to allow the ethanol content in gasoline to be increased from 10% ...

    In line with the observations in Japan, hydrous ethanol is known to be less corrosive than anhydrous ethanol. The reaction mechanism is 3 EtOH + Al -> Al(OEt) 3 + 3 ⁄ 2 H 2 at lower-mid blends. When enough water is present in the fuel, aluminum will react preferably with water to produce Al 2 O 3 , repairing the protective aluminum oxide layer.

    Sugarcane ethanol has an energy balance seven times greater than corn ethanol. [101] As of 2007, Brazilian distiller production costs were 22 cents per liter, compared with 30 cents per liter for corn-based ethanol. [102] Corn-derived ethanol costs 30% more because the corn starch must first be converted to sugar before distillation into ...

    The ethanol-powered "flex" vehicles, as they are popularly known, are manufactured to tolerate hydrated ethanol , an azeotrope composed of 95.6% ethanol and 4.4% water. [ 21 ] The Honda CG 150 Titan Mix was launched in the Brazilian market in 2009 and became the first mass production flex-fuel motorcycle sold in the world.

    From 1998 to 2004, the price of gasoline fluctuated between $0.26 and $0.53 per liter ($1 and $2/U.S. gal). [94] After 2004, the price increased until the average gasoline price reached a high of $1.09 per liter ($4.11/U.S. gal) in mid-2008 but receded to approximately $0.69 per liter ($2.60/U.S. gal) by September 2009.
