An engine oil having a base oil and a friction reducing amount of an oil soluble sulfurized or unsulfurized oxymolybdenum complex prepared from reacting, in the presence of a polar promoter, an acidic molybdenum compound and a basic nitrogen compound and a low concentration of a sulfurized oxymolybdenum dialkyldithiocarbamate; employed together to provide at least 450 parts per million of molybdenum and less than 175 parts per million of molybdenum from the dialkyldithiocarbamate, both on the basis of the engine oil.
Huile à moteur composée d'une base d'huile avec une quantité d'un complexe oléosoluble sulfuré ou non d'oxymolybdène suffisante pour réduire la friction, obtenu en faisant réagir, en présence d'un promoteur polaire, un composé de molybdène acide et un composé basique de l'azote avec une faible concentration d'un dialkyldithiocarbamate d'oxymolybdène sulfuré; les deux sont employées ensemble pour donner au moins 450 parties par million de molybdène et moins de 175 parties par million de molybdène à partir du dialkyldithiocarbamate, les deux mesures étant exprimées en fonction de l'huile à moteur.
