    Abstract: A two-cycle engine lubricant comprising from about 10% to about 30% low ash detergent inhibitor; from about 10% to about 45% bio-based ester selected from the group consisting of castor oil, a synthetic polyol-based ester and mixtures thereof; from about 14% to about 37% polyalphaolefin; from about 7% to about 18% synthetic ester; from 2% to about 10% surfactant; and from about 2% to about 5% pour point depressant; by weight of the lubricant. Optionally, the subject two-cycle lubricant can also comprise up to about 20 weight percent solvent, such as Stoddard solvent, to improve miscibility of the lubricant with gasoline fuel. The subject lubricant can be pre-packaged with gasoline for use with small engines not equipped for direct lubricant injection. A method for making the subject lubricant composition so as to resist subsequent separation of the components into layers is also disclosed.
