for a few other facts:

In January 2011 the U.S. Environmental Protection Agency (EPA) granted a waiver to allow up to 15% of ethanol blended with gasoline (E15) to be sold only for cars and light pickup trucks with a model year of 2001 or later.

In 1896, Henry Ford designed his first car, the "Quadricycle" to run on pure ethanol.[27] In 1908, the revolutionary Ford Model T was capable of running on gasoline, ethanol or a combination.[27]
[28]

[29] Ford continued to advocate for ethanol fuel even during the prohibition, but lower prices caused gasoline to prevail

As of 2005, 68% of American flex-fuel car owners were not aware they owned an E85 flex.[9]
[10] Flex and non-flex vehicles looked the same. There was no price difference. American automakers did not label these vehicles.[10]
[44] In contrast, all Brazilian automakers clearly labeled FFVs with text that was some variant of the word Flex. Beginning in 2007 many new FFV models in the US featured a yellow gas cap to remind drivers of the E85 capabilities.

not everyone agrees that it could or should be used in a crossfire I for one think 33% could be used if not all the time then at least on race day. I am not telling any one to use it. read everything you can before you do. here is where it was posted in years before. jim
