Abstract
This specification covers a fuel blend, nominally 75 to 85 volume % denatured fuel ethanol (Ed75-Ed85) and 25 to 15 additional volume % hydrocarbons for use in ground vehicles with automotive spark-ignition engines. Fuel ethanol (Ed75-Ed85) shall conform to the performance requirements prescribed. Fuel ethanol (Ed75-Ed85) shall be visually free of sediment and suspended matter. The hydrocarbon/aliphatic ether blend content, vapour pressure, acidity, pH requirements, gum content, inorganic chloride, water requirements, copper requirements, and sulphur requirements shall be tested to meet the requirements prescribed.
