Because high-temperature antifriction additives in motor oils must have low ash content, certain ashless thiophosphates were evaluated for their antifriction properties. The ashless thiophosphates were on the whole better in antiwear and antifriction properties than corresponding dithiophosphates. The replacement of diethylenetriamine by triethylenetetramine in the ashless thiophosphates leads to a certain improvement in the antiwear and antifriction properties, and the reasons for this higher efficiency were studied. Finally, the amidothiophosphates are recommended as promising materials for use as ashless antifriction and antiwear additives in lubricating oils.
