ABSTRACT:
A lubricating oil composition for internal combustion engines giving improved soot dispersancy. That lubricating oil composition has a mixture of borated and carbonated polyalkylene succinimides derived from different molecular weight polyalkylenes. The molecular weight of the polyalkylenes from which the carbonated polyalkylene succinimide is derived is at least 300 greater than the molecular weight of the polyalkylenes from which the borated polyalkylene succinimide is derived.
