ABSTRACT:
This invention encompasses a lubricating oil composition contaminated with at least about 0.3 wt % of a biodiesel fuel or a decomposition product thereof, based on the total weight of the lubricating oil composition, comprising:a. a major amount of base oil of lubricating viscosity; andb. a diarylamine compound,wherein, the amount of the diarylamine compound is at least about 0.1 wt. %, based on the total weight of the lubricating oil composition.Methods of using the lubricating oil compositions are also described.
