Summary

  1. 1.

    The lubricity of diesel fuels decreases almost proportionally with decreasing viscosity and increasing content of water. The variation in viscosity of commercial diesel fuels within the limits of the GOST standard may be equivalent to a twofold decrease in lubricity, and increases in water content up to 1.0% may give a threefold decrease in lubricity.

     
  2. 2.

    An increase in fuel acidity up to 1–2 mg KOH/100 ml gives a considerable improvement in lubricity. In the caustic treatment of fuels, it is inadvisable to reduce the acidity below this level.

     
  3. 3.

    Sulfur compounds, particularly mercaptans, are detrimental to the lubricity of diesel fuels. Hydrotreated diesel fuels are generally the same in lubricity as low-sulfur diesel fuels.
