Abstract: A LUBRICATING OIL COMPOSITION HAVING AS AN ANTIOXIDANT AND ANTIWEAR ADDITIVE A MIXTURE OF (1) OF PHOSPHOROTHIONYL OR PHOSPHONYL SULPHIDE OF THE FORMULAE

R1-O-P(=X1)(-O-R2)-(S)N-P(=X2)(-O-R4)-O-R3, OR

(-O-A1-O-)>P(=X1)-(S)N-P
WHERE R1, R2, R3 AND R4 ARE HYDROCARBYL GROUPS A1 AND A2 ARE DIVALENT HYDROCARBON GROUPS, X1 AND X2 ARE OXYGEN OR SULPHUR, AND N IS AN INTEGER OF 1 TO 4 AND (2) AN ORGANIC AMMONIUM THIOPHOSPHATE OF THE FORMULAE

R5-X1-P(=X3)(-X2-R6)-S(-) HN(+)(-R7)(-R8)-R9, OR

(-X1-A3-X2-)>P(=X3)-S(-) HN(+)(-R7)(-R8)-R9

WHERE R5, R6 AND R7 ARE HYDROCARBYL GROUPS, A3 IS A DIVALENT HYDROCARBON GROUP, X1, X2 AND X3 ARE OXYGEN OR SULPHUR, R8 AND R9 ARE HYDROGEN OR HYDROCARBYL GROUPS.
