Definitions

  • the present invention relates to an engine oil composition for automobiles. More particularly, the invention relates to the long life and fuel-saving engine oil composition which can suppress the friction loss in the engine to a low level for a long time.
  • engine oil compositions have been required to possess various performances such as wear resistance, oxidation stability, and detergent dispersibility. Recently, in order to suppress the earth from getting warmer due to increase in the content of CO 2 in the atmosphere, how to improve the mileage of the automobiles is an important problem. Accordingly, the fuel saving has been also strongly required with respect to the engine oils.
  • the engine oil composition is composed of a mixture of a base oil purified from petroleum, added with additives such as a detergent, an antioxidant, an anti-wear agent, and a viscosity index improver.
  • additives such as a detergent, an antioxidant, an anti-wear agent, and a viscosity index improver.
  • the viscosity of the engine oil is lowered by decreasing the viscosity of the base oil or changing the viscosity index improver.
  • friction modifier FM has recently come to be added so as to reduce the wearing in the boundary lubricating area.
  • organic molybdenum compound such as molybdenum dithiocarbamate (MoDTC) and oxymolybdenum organo phosphodithioate sulfide (MoDTP) are highly effective as described in JP-B 3-23595 (EP-A-113045).
  • MoDTC contains no phosphorus, increase in its addition amount does not cause decrease in the catalytic activity.
  • MoDTC has a small friction-mitigating effect, it may be considered that MoDTC is used in combination with zinc dithiophosphate (ZnDTP) as an anti-wear agent so as to supplement the wear-mitigating effect of the former.
  • ZnDTP has been frequently used, as antioxidant and anti-wear agent, in the engine oil compositions.
  • ZnDTP contains phosphorus and gives adverse influence upon the exhaust gas catalyst as mentioned above, its addition amount is limited so that good friction-mitigating effect cannot unfavorably be maintained for a long time.
  • MoDTC be used in combination with a sulfur-based extreme pressure additive (See JP-B 5-83599, JP-A-61 127 797). This combination does not afford adverse effect upon the exhaust gas catalyst, but it encounters a practically great problem upon the engine oil composition in that wear largely occurs in the valve train system.

  • the present inventors discovered that the combination of MoDTC and ZnDTP with a polysulfide compound can remarkably prolong the performance of the low fuel consumption rate, that is, can maintain the friction-mitigating effect of the engine oil for a long time without affording adverse influence upon the exhaust gas catalyst. Based on this discovery, the inventors have accomplished the present invention.
