Abstract
The air release rate of lubricating compositions is significantly enhanced when the composition is formulated with one or more vinyl aromatic-olefin block copolymers that forms a micelle-like structure in the oil. Compositions having the specified copolymers retain less than about 2.5% air after 1 min. at 50° C. when tested by ASTM D 3427.
