[origin: EP0903399A1] Lubricating oil contains (a) thiophosphoric ester(s) (I), (b) dithiophosphoric esters or phosphoric thioesters (II) and (c) oil additive(s) (III) selected from polyol partial esters, amines and epoxides. The thiophosphoric esters (I) and dithiophosphoric ester or phosphoric thioesters (II) are of the following formulae: R1, R2, R3 = 3-20 C hydrocarbyl; X = O or S; R1', R2', R3' = optionally substituted 3-20C hydrocarbyl . An Independent claim is also included for a concentrate containing (I), (II) and (III).
