why does some gasoline contain 10% ethanol?

government nonsense

The 2005 energy bill mandated that 4 billion gal­lons of renewable fuel (mostly corn-based ethanol) must be added to the gasoline supply in 2006. That amount rises to 4.7 billion gallons for 2007 and 7.5 billion in 2012. These targets represent a large per­centage increase in ethanol use but are still only a small fraction of the 140 billion gallons of gasoline that the U.S. currently uses every year.

1988 Denver, Colorado, mandated ethanol oxygenates fuels for winter use to control carbon monoxide emissions. Other cities followed.

1990 Clean Air Act Amendments - Mandated the winter use of oxygenated fuels in 39 major carbon monoxide non-attainment areas (based on EPA emissions standards for carbon dioxide not being met) and required year-round use of oxygenates in 9 severe ozone non-attainment areas in 1995.

1992 The Energy Policy Act of 1992 (EPAct) was passed by Congress to reduce our nation's dependence on imported petroleum by requiring certain fleets to acquire alternative fuel vehicles, which are capable of operating on nonpetroleum fuels. The Clean Air Act (1990) and Alternative Motor Fuels Act (1998 & 1992) contain provisions for mandating oxygenated fuel (RFG =Ethanol and MTBE). Requirements set for 2 types of clean-burning gasoline, RFG Federal Reformulated Gasoline and Wintertime Oxygenated Fuel.

1995 The EPA began requiring the use of reformulated gasoline year round in metropolitan areas with the most smog.

the problem we can make our own gasoline but the government will not allow us to.

No, i did not say drill here drill now !!!

Yes i said we can make our gasoline, we currently have the ability to make synthetic gasoline......how about that.....shocking isn't it.

Money ? Greed? haaa
