Heavy duty fleets using B5-B20 as common diesel alternatives

In Michigan, as the U.S. trucking industry faces new federal limits on greenhouse gas emissions, a University of Michigan team surveyed fleet managers to gauge their views on fuel usage, fuel economy and fuel-saving technologies. The survey results, released with the American Transportation Research Institute, include responses from nearly 100 heavy-duty fleet managers who operate more than 114,500 truck-tractors and haul 9 billion tons of freight across 1.8 billion miles annually. Every heavy-duty fleet in this survey currently uses diesel fuel, with biodiesel blends B5, B10 and B20 being the most common alternatives.
