Abstract
A lubricant in the form of a water or oil insoluble solvent in oil emulsion is described where a base (soluble or dispersible in said oil-insoluble solvent or water) is present in the dispersed phase. These lubricants are beneficial in various applications such as internal combustion engines where the oil needs enough basicity to neutralize any inorganic acids generated by sulfur present in the fuel.
