The facts on Ethanol!The basic story on ethanol mileage and cost.Some Ethanol proponents claim it doesn't hurt their mileage, but this goes against physics, and you will not find the ethanol lobby making such fraudulent claims--they could be sued. But just to be sure, zFacts analyzed all of EPA's ethanol mileage tests for one year and, big surprise, ethanol gave exactly 2/3 the mileage of gasoline Unfortunately it's very expensive. The USDA tells us that ethanol cost 57 cents more per gallon on average over the last 25 years and it still does. Put that together with the fact that it takes 1.53 gallons to equal a gallon of gasoline. EPA has measured the gas mileage of 2006 flexible fuel models. For the 31 models they tested the average reduction is 26 percent fewer miles per gallon. For example a car that gets 30 mpg on regular would typically get 22.2 mpg with E85. This is exactly what is predicted from the fact that E85 has less energy per gallon than gasoline.
For these calculations, the EPA assumes that E85 costs $2.00 and regular $2.20 gallon. Obviously they are on the low side, especially for ethanol, but this proportion is similar to what DOE predict for the next few years. The loss in mileage more than makes up for the cost savings, and on average the EPA predicts driving on E85 will cost 23 percent more than driving on regular.

I've already drilled the center of the bolt out with about 7/64" drill bit the entire length of the bolt. Only one end of the bolt is visible. I tried to use an easy out but it wasn't budging and I didn't want t
