US Classification:
508364, 363365, 363431
Abstract:
This invention relates to synergistic antiwear compositions comprising an organomolybdenum complex and an organic sulfur compound selected from 2,5-dimercapto-1,3,4-thiadiazole derivatives, bisdithiocarbamate esters, metal dithiocarbamates, metal phosphorodithioates and phosphorodithioate esters. The organomolybdenum complex is a reaction product prepared by reacting 1 mole fatty oil, 1. 0 to 2. 5 moles diethanolamine and a molybdenum source. Lubricating compositions containing the synergistic compositions possess good antiwear properties and improved oxidation stability.

Abstract:
Lubricating compositions containing a major amount of a base oil and an effective amount of an additive component having at least one compound of formula (I): ##STR1## where R is one of the following radicals, methyl, ethyl, n-propyl, i-propyl or a combination thereof, and n=0-8. In a preferred embodiment, R is a methyl radical and n=2-3. The lubricating compositions provide improved lubricating performance, particularly by inhibiting oxidation and improving thermal stability.
