摘要:
A lubricant composition of (a) an oil of lubricating viscosity; (b) a dispersant comprising the condensation product of a carboxylic functionalized polymer with an aromatic amine having at least 3 aromatic rings and at least one primary or secondary amino group; and (c) an overbased metal detergent comprising an oil-soluble neutral metal salt component and a metal carbonate component, provides good seal and corrosion performance. The total amount of neutral metal salt component in the lubricant composition is at least about 0.75 percent by weight and the sulfated ash level of the lubricant composition is less than about 1.1 percent.
