I recently read an article that stated a guy who builds ethanol plants and is on the ethanol board donated a pickup truck to a school. The students took it apart and after over 105,000 miles burning E-85 except when it was not availalbe, this gasoline only truck had no damage to anything. A man who has been dismantling vehicles over 40 years claimed the parts that come in contact with the ethanol are identical except fuel injectors that are larger in the multi-fuel vehicles. The article claimed no damage to catalytic converters, or anything that comes in contact with E-85. There was mention of oxygen sensors but the article claimed the oxygen sensor was probably bad prior to burning E-85. Replacing the sensor solved the problem with the engine light, and it did'nt return. Also a person did a test with different mixtures and determined for his vehicle the most cost effective was E-70. Has anyone here any experience with experiments concerning this?
