SCOTTSDALE, Ariz., Dec. 15, 2010 (GLOBE NEWSWIRE) -- Green Planet Group, Inc. (OTCBB:GNPG) announced today that its wholly owned subsidiary, Xentx Lubricants, has completed its initial locomotive tests in North Carolina. As most are aware, there is an ever increasing pressure from the Environmental Protection Agency (EPA) on the diesel engine manufactures to produce engines that are more fuel efficient and thereby reduce emissions and odors. In addition, the demand to reduce emissions and improve efficiency of older engines continues. The primary goal of these tests was to reduce the black smoke (soot) and increase the locomotive's power. Adding Xentx Diesel Fuel Treatment to the diesel fuel resulted in eliminating all of the black smoke, thereby improving combustion and improving power. These locomotive tests were organized and performed by Mr. Michael Covington, CEO and President of Green Equipment Solutions, who stated that the results were "astonishing, virtually all of the black smoke disappeared." The success of these tests has resulted in other major railroads becoming interested in performing their own tests. "Although these locomotive tests are extensive and time consuming," states Edmond Lonergan, President/CEO of Green Planet Group, "when completed, they will result in long term, large revenue contracts. In 2007 and 2008, the freight rail system in the U.S. consumed just over 4 billion and 3.9 billion gallons of diesel fuel, respectively. Green Planet's goal is to eventually treat 10% of this fuel which would result in additional annual revenues of $7.8 million," concluded Mr. Lonergan.
