Can all cars use 10% ethanol?
All gasoline engine vehicles can use E10. Currently, only flex-fuel and light-duty vehicles with a model year of 2001 or newer are approved by the EPA to use E15. Flex-fuel vehicles can use any ethanol-gasoline blends up to E85. The energy content of ethanol is about 33% less than pure gasoline.

Who discovered ethyl alcohol?
Ethanol was first prepared synthetically in 1826, through the independent efforts of Henry Hennel in Great Britain and S.G. Sérullas in France. Michael Faraday prepared ethanol by the acid-catalysed hydration of ethylene in 1828, in a process similar to that used for industrial ethanol synthesis today.
What was the average price of ethanol in 2006?

- According to the Renewable Fuels Association (RFA), ethanol production has increased by an average of almost 22 percent per year from 2000 through 2007, as seen in the figure below. Over this period, the number of ethanol plants more than doubled, to 134. By January 2008, industry capacity stood at 7.9 billion gallons per year.
Does the ethanol mandate cause food prices to rise?
- Critics of the U.S. ethanol mandate argue that this increase in commodity prices has led to increased food prices worldwide. In the U.S., the Consumer Price Index for food and beverages increased by more than 4.5 percent last year, following an average increase of 2.5 percent from 20.
