How does ethanol affect gas mileage?
While there are many variables that affect fuel economy (weather, car condition, road grade, tire pressure, air conditioner use, etc.), studies indicate that fuel economy with ethanol-enriched fuels may decrease, but not likely with E10. E85 has approximately 27% less energy then gasoline, but fuel economy loss varies between 10 to 25%.
Studies have indicated that fuel economy with ethanol-blended fuels may decrease. However, it is not likely with E10. E85 has approximately 27% less energy then pure gasoline, but fuel economy loss varies from 10 to 25%. What is ethanol made from? Ethanol is made by fermenting almost any material that contains starch. Grains such as corn, sorghum, potatoes, and sugarcane are good sources, but new technology makes the creation of ethanol from cellulosic material such as corn stalks, paper pulp, and switch grass possible. How is ethanol made? Ethanol is produced by taking the starch or sugar portion of feedstock and fermenting it. The fermented starch is then distilled into alcohol. The excess water is removed so the resulting ethanol, or ethyl alcohol, is pure, or 200 proof. How much ethanol can be made from a bushel of corn? A bushel of corn produces about 17 lbs of carbon dioxide, 16 lbs. of distiller’s grains and 2.8 gallons of ethanol.
