Abstract:
A lubricating composition having improved high and low temperature properties is disclosed. More specifically, the addition of a certain ethylene copolymers having a Melt Index of at least about 40 g/10 mins. to a mixture comprising (1) a lubricating oil, (2) a thickener, and (3) a VI improver results in a lubricating composition which has both excellent high temperature adhesiveness and low temperature slumpability.
