摘要：
A synergistic demulsifier composition for the improvement of demulsification properties and method of making said composition is disclosed along with a lubricant composition containing same. The demulsifier composition consists of effective amounts of one or more demulsifier additives and one or more dispersants. The demulsifier additives consist of a first copolymer of propylene oxide and ethylene oxide and a second copolymer of propylene oxide and ethylene oxide. The dispersant can be an untreated polyalkene succinimide type dispersant, preferably an untreated polyisobutylene succinimide type dispersant.
