    Abstract: PROBLEM TO BE SOLVED: To obtain a lubricating oil composition nonproblematic in sludge formation and the deterioration of a sealing agent during a stop-and-go drive under high-humidity and low-temperature conditions by mixing an oil having lubricating viscosity with a specified thiocarbamate and an aromatic aldehyde and/or an oxirane-ring-containing epoxide. SOLUTION: This thiocarbamate is represented by formula I [wherein R1 and R2 are each a 3-5C alkyl, an aryl, or an aralkyl or they may be combined with each other to form an alicyclic or heterocyclic ring together with the N atom; n is 1 or 2; when n is 1, T is a monovalent metal or CR3R4(CR12R13)aQ (wherein a is 0 or 1; R3, R4, R12 and R13 are each H, an alkyl or an aryl; Q is formula II, III or the like (wherein R5 is H, an alkyl or an aralkyl); and when n is 2, T is a divalent metal or a hydrocarbylene). The aromatic aldehyde used is vanillin, for example. The epoxide used is an alkyl ester of a vegetable epoxide, for example. 2-50 pts.wt. aromatic aldehyde or the like is used per 10 pts.wt. thiocarbamate.

    Abstract: PROBLEM TO BE SOLVED: To obtain a lubricating oil composition nonproblematic in the formation of sludge and the deterioration of a sealing agent during stop-and-go drive under high-humidity and low-temperature conditions by mixing an oil having lubricating viscosity with and a nitrogen-containing dispersant comprising a Mannich reaction product derived from a specified phenol and an aromatic aldehyde and/or an oxirane-ring-containing epoxide. SOLUTION: A nitrogen-containing dispersant has a total alkali value of 30-160. A Mannich reaction product is formed from a phenol containing one 30C or higher aliphatic substituent, formaldehyde and an amine compound containing ethylenepolyamine. The aromatic aldehyde used is vanillin, for example. The epoxide having terminal and/or internal oxirane rings is a 1-8C alkyl ester of a vegetable oil epoxide, for example. The nitrogen-containing dispersant is used in an amount of 2-75 pts.wt. aromatic aldehyde or the like per 100 pts.wt. Mannich reaction product.

    Abstract: PROBLEM TO BE SOLVED: To provide a lubrication composition for improving the corrosion of copper-lead bearings of an engine which comprises a borated dispersant, a metal salt of a phosphorus-containing acid, a metal overbased composition and a borate ester. SOLUTION: A composition for reducing the corrosion of copper-lead bearings in a preparation is a composition comprising a major amount of a lubricating viscous oil and a minor amount of a corrosion reducing additive containing (A) a borated dispersant having a total base number of 20-160 on an oil-free basis; (B) a metal salt of a phosphorus-containing acid; (C) a metal overbased composition containing at least one of a carboxylate salt, a phenolate and a sulfonate salt in which the metal is lithium, sodium, potassium, magnesium or calcium; and, as an improvement, (D) a boric acid ester, the boric acid ester and the boric acid chloride dispersing agent, herein, giving 20 to about 800 ppm (mass) boron.
