Abstract
A hydrocarbon-soluble molybdenum complex of a hydrocarbon substituted thio-bis-phenol, e.g. the reaction product of 1-2 moles of nonyl phenol sulfides and one mole of molybdenum oxide (reacted if desired in the presence of an amine promoter), in combination with a sulfur donor provides lubricity activity to lubricating oils and other hydrocarbons including fuels.
