ASTM D5798 - Ethanol Fuel Blends for Flexible-Fuel Automotive Spark-Ignition Engines

We perform ethanol quality testing by Specification ASTM D5798, which covers the requirements for automotive fuel blends of ethanol and gasoline. These fuel blends are used in ground vehicles equipped with ethanol fuel blend flexible-fuel spark-ignition engines. Fuel produced according to this specification contains 51-83 volume % ethanol, and is referred to at retail as ‘Ethanol Flex-Fuel.’ ASTM D5798 formerly covered Fuel Ethanol (ED70-Ed85) for Automotive Spark-Ignition Engines, also known commercially as E85. The nomenclature ‘fuel ethanol’ has been changed to ‘ethanol fuel blends’ to distinguish this product from ASTM D4806 - Denatured Fuel Ethanol Specification.
