Abstract
A molybdenum complex of a lactone oxazoline dispersant, preferably an oil-soluble lactone oxazoline obtained as a reaction product of hydrocarbyl substituted lactone carboxylic acids, for example, polybutyl lactone carboxylic acid, with 2,2-disubstituted-2-amino-1-alkanols, such as tris-(hydroxymethyl) aminomethane (THAM), and their derivatives are useful additives in lubricating oils since both the sludge dispersant and antifriction properties of said oil are enhanced.
