<p>A base oil for lubricating oil, a lubricating oil composition containing the base oil and a phenol-based antioxidant and/or an organomolybdenum compound, and also an additive for a base oil for lubricating oil, consisting of a phenol-based antioxidant and an organomolybdenum compound are disclosed. The base oil and the lubricating oil composition containing the base oil are stable against NOx gas and are useful for use in internal combustion engines. The additive, when added to a base oil, provides a lubricating oil which is stable against NOx gas and can be used effectively in a NOx gas atmosphere.</p> |
