Abstract
This invention provides novel lubricating oil compositions comprising an organometallic additive, including a metal selected from Groups I, Ib, and VIII of the Periodic System of Elements, e.g. Na, K, Cu, Co, Ni or Fe, chelated with the reaction product of formaldehyde, an amino acid and a phenol, dissolved in a lubricating oil. Depending on the choice of the metal, the above organometallic additive imparts rust inhibition, sludge dispersant, wear reduction and anti-oxidant properties to said lubricating oil compositions.
