The Drawbacks of Using Ethanol Fuel Blends

Auto Trends Magazine - December 14, 2011

Most gaso­line pow­ered cars can also safe­ly run on an ethanol blend con­sist­ing of 10 per­cent ethanol and 90 per­cent gaso­line, known as E10 fuel. The EPA says cars fueled with either E10 or E85 (85% ethanol and 15% gaso­line for flex-fuel vehi­cles) will see a drop in fuel effi­cien­cy. Dri­vers using these ethanol-based fuels will expe­ri­ence low­er miles per gal­lon and high­er costs.
