| 5. According to a study by Cornell University, for every gallon of Ethanol produced, 1.4 gallons of energy is consumed in the process, compared to 0.15 gallons used in the manufacture of Gasoline.
6. It takes 1.5 gallons of ethanol to drive as many miles as one gallon of gasoline. Ethanol Response: This is a misleading statement since no one drives on pure Ethanol. Most motorists will not notice any difference in mileage using the standard 10% Ethanol blend. For trivia purposes, it takes only about 8 ozs. of MTBE to pollute an Olympic-size swimming pool and make the water virtually undrinkable. 7. Ethanol increases the vapor pressure of Gasoline by 1 psi, resulting in higher evaporative emissions of Volatile Organic Compounds, while tailpipe emissions of Acetaldehyde increase 150%. Ethanol Response: This is another example of twisting the truth. All Gasoline, whether it has Ethanol in it or not, has to meet relevant/government Standards with regards to vapor pressure and Gasoline is produced and blended accordingly. Therefore, Ethanol blends do not exceed any such Standards for vapor pressure. On the other side of the car, Ethanol blends significantly reduce tailpipe emissions, including reducing carbon monoxide emissions by up to 33%. In fact, such Ethanol blends are being progressively being made mandatory in many Metros around the World to help their clean air goals. While Acetaldehyde emissions may increase due to the higher oxygen content of Ethanol blends, the flip side is that Ethanol blends reduce Formaldehyde emissions significantly and Formaldehyde emissions are 50% more toxic then Acetaldehyde emissions, which are still very low. 8. Ethanol permeates the hoses and lines of automobile fuel systems resulting in a 50% increase in VOC emissions for pre 1995 cars. Ethanol Response: Again, not true. Ethanol compatible materials have been used by the automotive industry since the late 1970's when Ethanol began to be blended with Gasoline. 9. Ethanol dissolves oxide scale from the walls of pipes and tanks, subjecting the systems to internal corrosion, which leads to leaks. Ethanol Response: Again, this accusation is not true. While Ethanol has good detergent qualities, it actually helps keep tanks clean and prevents leaks. Since Ethanol has been used in many parts around the world, the various tank and pipe component manufacturers have developed products that work well with Ethanol blends. Content generated by S. K.
