ABSTRACT:
An additive, a lubricating oil composition which incorporates the additive, and a concentrate for a lubricating oil are disclosed. The additive includes (a) a halogenated copolymer prepared from ethylene, a C.sub.3 to C.sub.18 alpha-olefin, preferably a C.sub.3 to C.sub.8, or mixtures thereof, and at least one halogen, and (b) an amino-aromatic polyamine compound. Most preferably, the copolymer is prepared from ethylene, propylene and at least one polyene.
The lubricating oil composition comprises a major amount of an oil of lubricating viscosity and a minor amount, effective to impart viscosity index improvement, dispersancy and antioxidant properties to the oil, of the prescribed additive.
The concentrate comprises a diluent oil of lubricating oil viscosity and from about 1 to about 50 weight percent of the prescribed additive based on the total weight of the concentrate.
