SACRAMENTO, Calif., Oct. 3, 2013 /PRNewswire/ -- Greyrock Energy announced today that it has completed extensive testing of its premium diesel fuel at an advanced heavy duty diesel engine dynamometer laboratory.  

"While our fuel meets ASTM diesel fuel specifications, it is important to understand how the fuel performs in today's heavy duty diesel truck engines," Said Dr. Dennis Schuetzle, Greyrock's Chief Technology Officer.  "The fuel performed very well, showing reduced particulate emissions, carbon monoxide, hydrocarbons and carbon dioxide emissions."

Greyrock's synthetic diesel fuel is produced from natural gas using Greyrock's proprietary MicroGTL systems.  The fuel significantly exceeds ASTM D975 standards in critical areas such as cetane, sulfur, lubricity and lower aromatic content.  These premium properties result in the improved performance over traditional diesel as outlined above.

Greyrock Energy is dedicated to changing the way that the world produces liquid transportation fuels, using clean, affordable natural gas, natural gas liquids, biogas, and waste hydrocarbon gas streams. Greyrock believes that its MicroGTL technologies will have the same impact on distributed fuel production that the gas turbine has had on distributed energy production.
