ABSTRACT:
Disclosed is a diesel engine oil composition containing a lube oil base and one or more metallic detergent-dispersants selected from among a perbasic alkaline earth metal sulfonate, phenolate, and salicylate. The total phosphorus content of the composition is suppressed to 100 ppm by weight or less, to thereby provide diesel engine oil compositions having excellent oxidation stability and wear resistance.
