The technology of the invention relates to compression-ignition internal combustion engine lubricants, particularly those having at least improved sealing performance, reduced build-up and excellent durability. The present invention relates to a lubricant composition with a low dispersant content comprising (a) an oil of lubricating viscosity, (b) from about 0.5 percent by weight to 3.0 percent by weight of a substituted phenol compound. by an oxyalkylated hydrocarbyl, (c) from about 0.01 percent by weight to 2.6 percent by weight of a polyalkenylsuccinimide dispersing agent, and (d) from about 0.05 percent by weight to 2, 0 percent by weight of a polyolefin dispersing agent viscosity modifier, and the zinc containing lubricating composition in a proportion of less than about 700 ppm by weight of the composition. |
