    摘要: An additive composition providing improved low temperature viscosity, corrosion and detergent properties when used in lubricating oils for internal combustion engines is presented. The additive composition comprises an unsulfurized carboxylate detergent-dispersant additive having been modified by incorporation of from about 3.2 wt % to 7.5 wt %, based on the total additive composition, of an alkaline earth metal salt of a linear, saturated carboxylic acid having from about 16 to about 20 carbon atoms and wherein the additive composition has a superalkalinization ratio of less than about 1.4:1, a TBN of less than about 200 and a sediment value of less than about 0.2% by volume.
