<p>Hydrocarbon soluble organo molybdenum complexes obtained the reaction product of a hydrocarbyl substituted thio-bis-phenol, e.g. 2,21-thio-bis (4-iso-nonyl phenol), with a molybdenum compound, e.g. molybdic oxide in the presence of a suitable promoter, e.g. ethanol-anine, are useful hydrocarbon additives, particularly in combination with an oil-soluble sulfur donor. e.g. a metal dialkyl dithiophosphate to provide an additive combination for lubricating oils since the lubricating compositions comprising these co-additives exhibit improved anti-friction and anti-wear properties.</p> |
