Ethanol Blends

Determination of the Potential Property Ranges of Mid-Level Ethanol Blends

The American Petroleum Institute (API) sponsored a study to support an improved understanding of the fuel volatility and octane number impacts resulting from the blending of ethanol in motor gasoline at concentrations within the range of 10 to 30% by volume. The intent was to develop information for use in discussions regarding the need for changes in ASTM specifications to accommodate mid-level gasoline/ethanol blends. The report below summarizes that effort.
