As the price of middle distillate fuels continues to rise, the use of bioderived materials as fuel blending stocks becomes attractive. In the present research, a severely hydrotreated diesel fuel was blended in concentrations of 10-20% and was shown to have significantly better lubricity as measured by ASTM D6078/BOCLE, ASTM D6079/SLBOCLE, and BOTD. The current ASTM methods showed a wide differentiation between the hydrotreated fuel and the soy blends. The differences in the BOTD measurements were not as large.
