Title: (DE) SCHMIERÖLZUSAMMENSETZUNG
(EN) LUBRICANT OIL COMPOSITION
(FR) COMPOSITION D'HUILE LUBRIFIANTE
Abstract:
(EN) The present invention provides a lubricating oil composition improved in fuel-saving properties by reducing lubrication resistance within the same viscosity grade oils. The lubricating oil composition comprises a lubricating base oil and a viscosity index improver with a PSSI of 30 or lower blended such that the viscosity index of the composition is 160 or greater and the 100°C kinematic viscosity loss after shearing is 15 percent or less.
(FR) L'invention concerne une composition d'huile lubrifiante qui, pour une même qualité de viscosité, atteint une meilleure réduction de la résistance à la lubrification pour augmenter la performance d'économie d'énergie du lubrifiant. La composition d'huile lubrifiante se caractérise en ce qu'une huile lubrifiante de base est mélangée à un améliorant de l'indice de viscosité de 30 PSSI ou moins, pour que l'indice de viscosité de la composition atteigne 160 ou plus, et pour que son taux de chute de la viscosité cinématique à 100 °C après le cisaillement soit de 15 % ou moins.
