摘要： The task is to provide a lubricating oil composition capable of maintaining oxidation stability over a long period of time by not only making oxidation stability evaluated by an RPVOT value excellent even while using a base oil comprising a certain amount or more of tertiary carbon atom but also suppressing a rise in acid value in the initial stage. Said task is attained by providing a lubricating oil composition comprising a base oil (X) comprising tertiary carbon atom at a content of 8.0 at% or more based on the total carbon of hydrocarbons, and an antioxidant (Y) comprising an amine-based antioxidant (A), a phenol-based antioxidant (B), and a phosphor-based antioxidant (C), and satisfying the following requirements. Specifically, the amine-based antioxidant (A) comprises a diphenylamine compound (A1) having a specific structure. The phenol-based antioxidant (B) comprises a hindered phenol compound (B1) having an ester structure. Furthermore, the total content [(A1) + (B1) + (C)] of the diphenylamine compound (A1), the hindered phenol compound (B1) having an ester structure, and the phosphor-based antioxidant (C) was set to greater than 1.0 mass% and 2.0 mass% or less based on the total amount of the lubricating oil composition.

摘要： This invention relates to lubricating compositions containing hydroxyalkane phosphonic acids and derivatives thereof. More specifically, this invention relates to hydroxylakane phosphonic acids which can be reacted to form salts with basic materials, including overbased detergents, dispersants and amines. These materials can be particularly useful in lubricating compositions. The hydroxyalkane phosphonic acid is represented by the following formula: wherein X is oxygen, sulfur or a secondary amino group, n is an integer from 1 to 8, Y is hydrogen or a phosphonic acid group and R is an alkyl group having from 1 to about 100 carbon atoms.

摘要： The concentrates comprise specified proportions of diluent oil, an organic sulfur-containing antiwear and/or extreme pressure agent, an ashless dispersant, a dimethyl ester of an aliphatic phosphonic acid in which the aliphatic group has an average in the range of about 12 to about 24 carbon atoms, and a 3-hydrocarbyl-2,5-diketopyrrolidine in which the hydrocarbyl group is an alkyl or alkenyl group having an average in the range of about 12 to about 30 carbon atoms. By using weight ratios of diketopyrrolidine to the dimethyl phosphonate of at least 3:1, the concentrate remains homogeneous at temperatures at least as low as 12 DEG C. When utilized as a top treat in gear oils formulated with conventional GL-4 and GL-5 gear additive packages substantial improvements in limited slip axle performance can be realized.
