    摘要: Disclosed is a method for improving compatibility of a fluorocarbon elastomer seal with a lubricating oil composition containing (a) a major amount of a base oil of lubricating viscosity; and (b) one or more dispersants containing one or more basic nitrogen atoms. The method involves adding to the lubricating oil composition an effective amount of one or more fluorocarbon elastomer compatibility improving agents comprising 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 a saturated carboxylic acid, (ii) an anion of an α-, β- or γ-hydroxycarbonyl compound; (iii) an anion of an α-, β- or γ-hydroxycarboxylic acid, amide, or ester; (iv) an anion of an α-, β- or γ-aminocarboxylic acid; and (v) an anion of an α-, β- or γ-keto acid.
