Abstract
Abstract Disclosed are lubricating oil compositions containing from about 0.01 weight percent to about 5 weight percent of oil-soluble multifunctional additive having the general formula ##STR1## where A. X 1 is --S--CS--OR, --S--CS--NR 2 , --S--PS--(OR) 2 , or --O--P(OR) 2 , and X 2 and X 3 are chlorine, bromine, --S--CS--OR, --S--CS--NR 2 , --S--PS--(OR) 2 , --OP(OR) 2 , or R; or B. X 1 is --S--CS--OR, --S--CS--NR 2 , --S--PS--(OR) 2 , or --O--P--(OR) 2 , and X 2 and X 3 are chlorine, bromine, --S--CS--OR, --S--CS--NR 2 , --S--PS--(OR) 2 , --O--P--(OR) 2 or --HN--R' where R comprises hydrocarbyl groups or chlorine, bromine or hydroxy substituted hydrocarbyl; and R' comprises hydrocarbyl, or hydroxy, amine or amide substituted hydrocarbyl. The lubricating oil compositions have improved extreme pressure, dispersancy or anti-oxidant properties.
