A fully formulated lubricating oil has a lubricant additive concentrate providing reduced sludge formation. The fully formulated lubricating oil composition has therein at least one succinimide dispersant derived from a polyalkylene compound having from about 50 to about 85 % vinylidene double bonds in the compound, a metal containing detergent, at least one wear reducing agent, at least one antioxidant, and a hydrocarbon soluble titanium compound as a friction modifier (especially titanium oleate or titanium neodecanoate). The lubricating oil composition is also substantially free of molybdenum compounds. |
