E85 is not 15%.
E85 is what they have is countries like Brazil. It can have between 53% to 85% alcohol. This is also known as Flex Fuel.
Brazil has true flex fuel automobiles. This is because Brazil has very little petroleum reserves. However, they can grow sugar beets year round. Sugar beets are the best crop to grow and make ethanol. They are so good at making it there, they can export it here and be a lot cheaper than making it from corn. Except, that would not be beneficial for all the farmers in Iowa, where they have that caucus every four years.
Thanks.. I was unaware that you could get 53% alcohol in E85, I will check to see if that is the American definition however.
