Abstract
Hydrocarbon-soluble organo molybdenum complexes obtained as the reaction product of a hydrocarbyl substituted hydroxy alkylated amine e.g. N,N',N'-tris(2-hydroxy ethyl)-n-tallow-1,3-diaminopropane, with about one molar equivalent of a molybdenum compound, e.g. ammonium molybdate, 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.
