ASTM approves new 100 octane standard that could boost ethanol blending

March 16, 2017 |

In Pennsylvania, a new ASTM International standard that supports 100 octane fuel could help drive innovation in the auto industry as cars with higher-performance engines are introduced into the global marketplace.

This new standard responds to a years-long effort by engine manufacturers and others to create a broadly accepted specification for this higher-octane fuel which can withstand higher compressions before igniting, thus extracting more energy from a given quantity of fuel.

The new standard (D8076, Specification for 100 Research Octane Number Test Fuel for Automotive Spark-Ignition Engines) was developed by a leading global standards organization, ASTM International, and its committee on petroleum products, liquid fuels, and lubricants (D02).

American Coalition for Ethanol welcomed a recently published ASTM International standard, which creates a broadly accepted specification for high-octane fuel that could help not only drive innovation in the auto industry, as cars with higher performance engines are introduced into the global marketplace, but growth within the ethanol industry, as these engines can utilize ethanol’s powerful octane boost with fuel blends between 25 and 40 percent.
