A lubricating oil composition which exhibits improved fuel economy and fuel economy retention, contains the combination of (a) a dithiocarbarmate of the formula R1(R2)N-C(:S)-S-(CH2)n-S-(:S)C-N(R2)R1 where R1 and R2 independently represent alkyl groups having 1 to 20 carbon atoms and n is an integer from 1 to 4; and (b) an oil soluble trinuclear friction modifying molybdenum compound, the two components functioning to provide an improvement in the friction reducing properties of the composition.
La présente invention concerne une composition d'huile de graissage qui assure une meilleure économie de carburant et un meilleur maintien de ladite économie. Cette huile renferme une combinaison (a) d'un dithiocarbonate de formule R<1>(R<2>)N-C(:S)-S-(CH2)n-S-(:S)C-N(R<2>)R<1> où R<1> et R<2> représentent chacun indépendamment des groupes alkyle possédant de 1 à 20 atomes de carbone et n est un entier compris entre 1 et 4; et (b)un composé de molybdène trinucléaire, soluble dans l'eau et modifiant les caractéristiques de friction, ces deux composants procurant une amélioration du pouvoir atténuateur des frottements de la composition.
