Your article on the ethanol blending barrier (Blending wall hinders ethanol industry growth, Jan. 8, 2009) was misleading on two counts.
It is true that the federal government has established a 10 percent blending limit. However, Minnesota has passed a 20 percent blending rule and is applying for a federal waiver. The article also leads us to believe that cars will not run correctly, according to the automakers, on more than 10 percent ethanol.
People all over the country are running their fuel injected cars on up to 50 percent ethanol with no performance or maintenance problems and significantly improved emissions results.
One test reported by David Blume used a variety of unmodified cars from a 1977 Mercedes to a 2004 Toyota Tacoma. Their computers adapted to the fuel change, ran fine and passed their smog tests (in California!) with flying colors.
If we just make the ethanol and cut our gasoline by 40-50 percent with it, that simple act can replace imported oil and all the foreign policy costs that go with it.
