Abstract: An additive package including an oil-insoluble additive, a method for formin g an additive package with an oil-insoluble additive and a lubricant in the fo rm of a dispersion of an oil-insoluble additive in oil is described where an oi l- insoluble solvent, e.g. water, can be used to help create the dispersed phas e. These packages, methods and lubricants are beneficial in various application s such as internal combustion engines where the oil benefits from functional additives that are not readily soluble in the oil. In many embodiments the o il- insoluble solvent is partially or fully removed before use.
