American Power Group Announces New S4000 Dual Fuel Series for High Horsepower Engines

LYNNFIELD, MA--(Marketwired - Oct 7, 2014) - American Power Group Corporation (OTCQB: APGI) announced today that its subsidiary, American Power Group, Inc. ("APG") will introduce its new S4000 Series Stationary Dual Fuel System at the High Horsepower (HHP) Summit October 7 - 9, 2014 at the Ernest N. Morial Convention Center, New Orleans, Louisiana. Lyle Jensen, American Power Group's Chief Executive Officer will participate on two HHP Summit panels (today, October 7^th at 3:30 PM "Drilling Engines and Conversion Kits: Optimizing Fuel Cost Savings" and Wednesday, October 8^th at 3:00 PM "Pressure Pumping Engine Optimization: Fracturing Your Fuel Costs") addressing APG's dual conversion solutions for drilling engines and high pressure pumping engine optimization. APG will also be located at booth 838 during the Summit.

The APG S4000 Series has been designed to maximize oil and gas field performance utilizing a wider range of pipeline and conditioned well-head gas quality across the various shale basins in North America. Hardware upgrades include new engine anti-knock protection technology, upgraded display information as well as improvements to the durability of the hardware given the remote and difficult operating conditions many engines perform under. Software upgrades include telematics remote monitoring, auto-CanBus synchronization and upgraded variable fuel utilization programs.

Ed Wolf, American Power Group's Director of Stationary Business Development stated, "Several well-known drilling service contractors have recently conducted side-by-side field performance evaluations between APG and other dual fuel solutions in order to baseline actual performance results versus claimed performance metrics. We have been very successful in these evaluations due to having the best price, best overall up-time, highest overall average displacement fuel savings and the best operational flexibility and adaptability in the field. APG's dual fuel design continues to be noted for its high up-time and ease of operation resulting in significant net savings at the lowest total cost of ownership." Mr. Wolf added, "As we expand into other shale basins across North America, we are facing a wider energy range of natural gas quality. With our new S4000 variable fuel utilization software, we are able to perform under more diverse conditions and maximize performance and improve economic payback for a larger number of oil and gas customers."

Lyle Jensen, American Power Group's Chief Executive Officer commented, "The initial feedback on our S4000 performance in the field has been excellent with side by side evaluation testing demonstrating higher uptimes and higher overall average diesel displacement running 4% to 5% better than our competition. APG's ability to handle a wider quality range of pipeline and field gas will open up new regional markets like the Williston/Bakken basin, one of the fastest growing shale areas with approximately 200 rigs operating over 1,000 eligible diesel engines. We have received our first order for a dual fuel rig in the Williston/Bakken area which will be installed in the near future."

About American Power Group Corporation
American Power Group's alternative energy subsidiary, American Power Group, Inc., provides a cost-effective patented Turbocharged Natural Gas® conversion technology for vehicular, stationary and off-road mobile diesel engines. American Power Group's dual fuel technology is a unique non-invasive energy enhancement system that converts existing diesel engines into more efficient and environmentally friendly engines that have the flexibility to run on: (1) diesel fuel and liquefied natural gas; (2) diesel fuel and compressed natural gas; (3) diesel fuel and pipeline or well-head gas; and (4) diesel fuel and bio-methane, with the flexibility to return to 100% diesel fuel operation at any time. The proprietary technology seamlessly displaces up to 75% of the normal diesel fuel consumption with the average displacement ranging from 40% to 65%. The energized fuel balance is maintained with a proprietary read-only electronic controller system ensuring the engines operate at original equipment manufacturers' specified temperatures and pressures. Installation on a wide variety of engine models and end-market applications require no engine modifications unlike the more expensive invasive fuel-injected systems in the market. See additional information at: www.americanpowergroupinc.com.
