A lubricating oil composition is disclosed which comprises (a) a major amount of an oil of lubricating viscosity; and (b) one or more non-halogen-containing oil-soluble titanium complexes comprising at least one ligand selected from the group consisting of (i) an anion of an &#x3b1;-, &#x3b2;- or &#x3b3;-hydroxycarbonyl compound; (ii) an anion of an &#x3b1;-, &#x3b2;- or &#x3b3;-hydroxycarboxylic acid, amide or ester; (iii) an anion of an &#x3b1;-, &#x3b2;- or &#x3b3;-aminocarboxylic acid; and (iv) an anion of an &#x3b1;-, &#x3b2;- or &#x3b3;-keto acid.

Lubricating oil compositions containing titanium complexes

The invention is directed to oil soluble additive compositions, lubricating oil compositions, and additive concentrates comprising the salt of (1) a molybdenum oxide, sulfide, or oxysulfide; (2) an amide reaction product of a carboxylic acid component and a polyamine component wherein the charge mole ratio (CMR) of the carboxylic acid component to the polyamine component is about 2:1 to 1:1; and (3) a post-treating agent.

Preparation of a post-treated molybdenum amide additive composition and lubricating oil compositions containing same

A lubricating oil composition is disclosed which comprises (a) a major amount of an oil of lubricating viscosity; (b) one or more non-halogen-containing oil-soluble titanium complexes comprising at least one ligand comprising an anion of a carboxylic acid; (c) one or more dispersants; and (d) one or more detergents, wherein the lubricating oil composition is free of any zinc dialkyldithiophosphate.

Lubricating oil compositions

Disclosed is a lubricating oil composition containing an oil of lubricating viscosity and a N,N,N',N&#x2032;-tetraalkyl-naphthalene-1,8-diamine and at least one additive selected from antioxidants, dispersants, and detergents which together provide superior oxidation inhibition and are suitable lubricants for automotive and truck crankcase lubricants; as well as transmission lubricants, gear lubricants, hydraulic fluids, compressor oils, diesel and marine lubricants.

Lubricating oil compositions containing a tetraalkyl-napthalene-1,8 diamine antioxidant

The invention is directed to oil soluble additive compositions, lubricating oil compositions derived from a process for preparing a sulfurized oil soluble molybdenum complex having reduced active sulfur comprising: reacting an acidic molybdenum compound with an amide derived from a carboxylic acid component an polyamine component in a ratio from 2:1 to 1:1; there after sulfurizing to provide a sulfurized oil soluble molybdenum which is subsequently treated with at least one compound capable of reacting with the active sulfur of step b).
