  The present invention provides a lubricating oil composition for internal combustion engines which includes a boronated imide-based dispersant, or the boronated imide-based dispersant and a non-boronated imide-based dispersant, in which a boron content (B % by mass) derived from the boronated imide-based dispersant and a nitrogen content (N % by mass) derived from the boronated imide-based dispersant or derived from the boronated imide-based dispersant and the non-boronated imide-based dispersant satisfy the following formula (I): N≧B+0.05 (I); and a phosphorus content (P % by mass) and a content of a metal component (M % by mass) derived from a metallic detergent on the basis of a total amount of the composition satisfy any of the following requirements A to C: A: P<0.03 and M<0.05; B: P<0.03 and 0.05≦M≦0.12; and C: 0.03≦P≦0.06 and M<0.05. The lubricating oil composition for internal combustion engines can be considerably reduced in content of ZnDTP having a large phosphorus content or a metallic detergent while maintaining a good wear resistance for aluminum materials.
