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. sub. 1 is --S--CS--OR, --S--CS--NR. sub. 2, --S--PS--(OR). sub. 2, or --O--P(OR). sub. 2, and X. sub. 2 and X. sub. 3 are chlorine, bromine, --S--CS--OR, --S--CS--NR. sub. 2, --S--PS--(OR). sub. 2, --OP(OR). sub. 2, or R; or B. X. sub. 1 is --S--CS--OR, --S--CS--NR. sub. 2, --S--PS--(OR). sub. 2, or --O--P--(OR). sub. 2, and X. sub. 2 and X. sub. 3 are chlorine, bromine, --S--CS--OR, --S--CS--NR. sub. 2, --S--PS--(OR). sub. 2, --O--P--(OR). sub. 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.
