ABSTRACT:
The present invention provides a composition containing (a) a substantially nitrogen free dispersant derived from the reaction product of: (i) a polyalkenyl-substituted acylating agent; and (ii) a polyol; (b) a primary metal hydrocarbyl dithiophosphate; (c) an oil of lubricating viscosity; and (d) optionally a viscosity modifier, wherein the composition contains about 35 ppm or less of nitrogen derived from a substantially nitrogen free dispersant. The invention further provides a process for preparing the composition and its use.
