when did they start adding ethanol to gasoline
Ethanol fuel in the United States Gasoline containing up to 10% ethanol began a decades-long growth in the United States in the late 1970s. The demand for ethanol produced from field corn was spurred by the discovery that methyl tertiary butyl ether (MTBE) was contaminating groundwater.[27][30] MTBE's use as an oxygenate additive was widespread due to mandates in the Clean Air Act amendments of 1992 to reduce carbon monoxide emissions. MTBE in gasoline had been banned in almost 20 states by 2006. Suppliers were concerned about potential litigation and a 2005 court decision denying legal protection for MTBE.[citation needed] MTBE's fall from grace opened a new market for ethanol, its primary substitute.[27] Corn prices at the time were around US$2 a bushel.[citation needed] Farmers saw a new market and increased production. This demand shift took place at a time when oil prices were rising.

Tetraethyllead By 2011, the United Nations announced that it had been successful in phasing out leaded gasoline worldwide. "Ridding the world of leaded petrol, with the United Nations leading the effort in developing countries, has resulted in $2.4 trillion in annual benefits, 1.2 million fewer premature deaths, higher overall intelligence and 58 million fewer crimes," the United Nations Environmental Programme said.[73][74] The announcement was slightly premature, as a few countries still have leaded gasoline for sale as of 2013 (see above).
