L-2353R Title: SULFUR-CONTAINING COMPOSITIONS, LUBRICANT, FUEL AND FUNCTIONAL FLUID COMPOSITIONS Abstract of the Disclosure This invention is directed to novel composi- tions comprising (A) certain sulfur compounds, and (B) at least one carboxylic detergent composition. The compositions of the invention are useful as additives in lubricants and functional fluids, fuels and aqueous systems. Lubricating, fuel and functional fluid compo- sitions containing the derivatives of the invention exhiblt improved antioxidant, anti-wear, thermal stabil- ity and/or extreme-pressure properties. The compositions of the invention comprise the combination of (A) at least one sulfur compound characterized by the structural formula Image (I) wherein R1, R2, R3, R4, G1 and G2 and x are as defined hereinafter; and (B) at least one carboxylic dispersant compo- sition prepared by the reaction of a hydrocarbon-substi- tuted succinic acid-producing compound with at least about one-half equivalent, per equivalent of acid-pro- ducing compound, of an organic hydroxy compound, or amine containing at least one hydrogen attached to a nitrogen atom, or a mixture of said hydroxy compound and amine.
