Diesel Fuel Lubricity: A Survey of 1994/95 Canadian Winter Diesel Fuels

A total of 54 Canadian Diesel Fuels were sampled in the winter of 1994/95. Both Regular and Low Sulfur (less than 500 ppm by mass sulfur) fuels were sampled. All the fuels were obtained directly from refineries and were intended for commercial sale. The fuel samples were evaluated for lubricity, as measured by the High Frequency Reciprocating Rig (HFRR) at 25 °C, and by the Scuffing load BOCLE (SLBOCLE) as developed by the Southwest Research Institute. Various relevant inspection properties were also determined. Total aromatic content and aromatic type (mono, di or poly) of the samples was also determined by High Pressure Liquid Chromatography (HPLC).

The lubricity evaluations obtained are discussed, and compared to the other parameters obtained.
