The additive is prepared by reacting a polyamine with an alkenyl succinic acid anhydride having a number average molecular weight of about 500 to about 10,000 at a temperature of 60.degree. C.-120.degree. C. to form mono-alkenyl succinimide, bis-alkenyl succinimide or a mixture of mono- and bis-alkenyl succinimide. 2-pyrrolidone-5-carboxylic acid is then added to form an acylated mono-alkenyl succinimide, bis-alkenyl succinimide or mixture of mono- and bis-alkenyl succinimide. The acylated mono-alkenyl succinimide, bis-alkenyl succinimide or mixture of mono- and bis-alkenyl succinimide is acylated with an acylating compound selected from the group consisting of glycolic acid, oxalic acid, lactic acid, 2-hydroxymethyl-propionic acid and 2,2-bis(hydroxymethyl) propionic acid at a temperature of about 150.degree. C. to about 185.degree. C., to form a mixed acylated mono-alkenyl succinimide, bis-alkenyl succinimide or mixture of mono- and bis-alkenyl succinimide and the mixed acylated mono-alkenyl succinimide, bis-alkenyl succinimide or mixture of mono- and bis-alkenyl succinimide is recovered.
