J.W. Stenger Trucking Tests EcoDual Natural Gas System
By Steve Pollock
Joe and Karen Stenger founded J.W. Stenger Trucking in 1991. The company has grown to 35 trucks, hauling a diversity of commodities, including flatbed, van and dump and serving the oil field industry, stamped truck parts and aggregates.
With a son, Joe Stenger, III flying an F15 in Afghanistan, Joe and Karen became very interested in implementing ways to reduce dependence on foreign oil. Recognizing a lack of fueling infrastructure for natural gas, Joe decided to try EcoDual, a dual fuel system that mixes natural gas with diesel fuel, providing economical operation and a cleaner burning engine with reduced emissions. The system switches to all diesel fuel if the natural gas is not available.
Joe received a grant from the state of Ohio to install EcoDual on one of his trucks. He chose a 2008 Peterbilt 386 with a 525 hp Cummins ISX engine. The truck was used on a dedicated run from Wheeling, West Virginia to Columbus, Ohio and back. Joe could find natural gas fueling stations along I-70 in Washington, Pennsylvania and in Columbus, Ohio.
Joe estimates his fuel savings at between 25-30% or $400 to $600 per week with a return on investment (ROI) in about 15-16 months. Annual fuel savings are about $24,000 per year. The truck has operated with the EcoDual System for about 2 years and 100,000 miles with a total of 600,000 miles on the truck. Since the rest of his fleet operates in other areas, Joe is waiting for additional fuel infrastructure before converting the rest of his trucks. For now Joe and Karen Stenger are proud to be a part of a solution toward energy independence by using an energy source that is provided completely within the United States.
