Abstract
Official abstract text for this publication.
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 oil-soluble titanium compounds.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for improving compatibility of a fluorocarbon elastomer seal with a lubricating oil composition having one or more dispersants containing one or more basic nitrogen atoms in an internal combustion engine containing fluorocarbon elastomer seals, the method comprising operating an internal combustion engine containing fluorocarbon elastomer seals with a lubricating oil composition comprising a) a major amount of a base oil of lubricating viscosity; (b)…
