Abstract (en)
[origin: WO9213933A1] The action of a crosslinked polyoxyalkylene polyiol demulsifier for a water-in-oil emulsion containing an ashless dispersant additive is enhanced by the use of a free dicarboxylic acid or anhydride. The invention has particular relevance to lubricating oils for marine use, especially trunk piston engine oils and system oils.
