With energy security, economic stabilization, and environmental sustainability being at the forefront of US policy making, the development of biodiesel production and use within the United States has been growing at an astonishing rate. According to the latest DOE energy report, biodiesel production and consumption in the US has decreased since its peak in 2008, but still remains an important factor in the US energy mix. However, despite recent studies showing that B5 has similar performance qualities to that of the currently used ultra-low-sulfur petroleum diesel (ULSD) fleet managers and corporations still remain hesitant regarding a switch to B5. This research examined the major areas of concern that arise with transitioning fleets from ULSD to B5 with the goal of alleviating those concerns with quantitative results from an actual fleet implementation and transition. In conjunction with the Pennsylvania Department of Transportation (PennDOT) a comparison of cost, cold weather fuel properties, engine performance, fuel economy, and maintenance and repairs was conducted using data obtained over 3 years from a pilot study. The results found that B5 performed as well or better than ULSD in all performance metrics.
