Title (EN) LUBRICANT OIL COMPOSITION
(FR) COMPOSITION D'HUILE LUBRIFIANTE
(JA) 潤滑油組成物
Abstract:
(EN) A lubricant oil composition that among those of the same viscosity grade, attains a further reduction of lubrication resistance to thereby enhance the energy saving performance of lubricant. The lubricant oil composition is characterized in that a lubricant base oil is blended with a viscosity index improver of 30 or below PSSI so that the viscosity index of the composition is 160 or higher and so that the ratio of 100°C kinematic viscosity drop after shear thereof is 15% or below.
(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.
(JA) 同一粘度グレードにおいて潤滑抵抗をさらに低減して潤滑油の省エネルギー性能をより高めることができる潤滑油組成物として、潤滑油基油に、PSSIが30以下の粘度指数向上剤を、組成物の粘度指数が160以上、かつせん断後の100℃動粘度低下率が15%以下となるように配合してなることを特徴とする潤滑油組成物が提供される。
