New compounds are derived from intra-molecular and inter-molecular, in the case of a polymer, sulphur bridged hydrocarbon rings of 12 carbon atoms. The hydrocarbon ring is preferably 1,5,9-cyclododecatriene. The compound also contains the residue of a dithiophosphoric acid containing two organic moieties. The new compounds are useful in major or minor amounts in lubricating oil compositions. The lubricating oil may be a hydraulic oil. The composition may also contain other conventional lubricant additives.
