Findings from a study by a team at the University of Oklahoma suggest that the stability of diesel fuel—i.e., either the biodegradation of diesel hydrocarbons or, by inference, the degree of biocorrosion—is independent of the concentration of organosulfur species in the fuel. In other words, accelerated biocorrosion associated with the use of ultra-low sulfur diesel [...]

Univ. of Oklahoma study suggests that biocorrosion associated with ULSD not related to level of sulfur in the fuel
The latest national survey of 100% biodiesel (B100) “blend stock” samples by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) found that 95% of the samples from 2011-12 met ASTM International fuel quality specifications. The ASTM standards serve as guidelines for industry and are designed to ensure quality at the pump for consumers [...]
Researchers at Purdue University have found that they can extend a flexible control strategy designed better to manage the lower fuel energy density and increased NOx emissions from biodiesel use to also address biodiesel variability due to feedstock and processing differences. A paper on their work is published in the International Journal of Engine Research. [...]
Ford’s all-new 2014 Transit full-size van, which goes on sale late next year, will be offered with a new 3.2-liter Power Stroke five-cylinder diesel. The new diesel engine, Ford’s second in North America, has already been applied in the global Ford Ranger truck sold in world markets (3.2 Duratorq TDCi 200). The new Power Stroke [...]
