2. Description of the Related Art Currently, the situation surrounding automobiles is becoming stricter, such as fuel efficiency regulations and exhaust gas regulations. Behind this are environmental issues such as global warming, air pollution and acid rain, and resource protection from concerns over the limited depletion of petroleum energy. At present, improvement of fuel efficiency is the most effective as these measures. In order to reduce the fuel consumption of automobiles, that is, to promote so-called fuel saving, we have also improved the automobile itself, such as reducing the weight of the automobile itself and improving the engine, as well as reducing the viscosity of engine oil to prevent friction loss in the engine. Improvement of engine oil, such as addition of a good friction modifier, is also an important factor. The engine oil acts as a lubricant between the piston and the liner, but since fluid lubrication is large in this portion, friction loss can be reduced by reducing the viscosity of the engine oil. For this reason, in recent years, the viscosity of engine oils has been reduced, but problems such as deterioration of sealability and increase in abrasion due to the reduction in viscosity of lubricating oil have newly occurred. In addition, the lubricating oil plays an important role in the lubrication of valve trains, bearings, etc. Cause it.
Therefore, reduction of friction loss due to lower viscosity of engine oil,
A friction modifier, an extreme pressure agent, and the like are added for the purpose of preventing abrasion.

[0003] Organic molybdenum compounds have an excellent friction reducing effect and are therefore added to various lubricating oils, but they are particularly effective in reducing fuel consumption in engine oils and are essential for fuel saving oils. Has become an additive. Even if the fuel-saving oil exhibits excellent fuel-saving performance at the new oil stage, it cannot be said to be an excellent fuel-saving oil if the performance cannot be maintained for a long time. Therefore, it is an important theme required for current fuel-saving oils to maintain the friction reducing effect even after long-term use.

[0004]

Among the organic molybdenum compounds, there is a molybdenum amine compound obtained by reacting an inorganic molybdenum compound such as molybdenum trioxide with a secondary amine (for example, Japanese Patent Publication No. 5-62639, Japanese Patent Publication No. 6-4866, etc.). However, the conventional one has not always been satisfactory in maintaining the friction reducing action (so-called long drain property) after long-term use.
Therefore, the present inventors have intensively studied a lubricant capable of maintaining excellent properties without significantly reducing the friction reducing action and the wear resistance action even after long-term use.
It has been found that a molybdenum amine compound obtained by reacting a compound containing a bivalent molybdenum atom with an amine compound having a specific structure is excellent in lubricity and long-term stability even after long-term use. Was.

[0005]

That is, the present invention provides a lubricating agent comprising a molybdenum amine compound obtained by reacting a compound containing a hexavalent molybdenum atom with an amine represented by the following general formula (1). Agent.
