Title
(EN) LUBRICANT COMPOSITION FOR INTERNAL COMBUSTION ENGINE
(FR) COMPOSITION LUBRIFIANTE POUR MOTEUR À COMBUSTION INTERNE
(JA) 内燃機関用潤滑油組成物
Abstract
(EN) This lubricant composition for an internal combustion engine comprises (A) a lubricating base oil, (B) magnesium salicylate, (C) calcium salicylate, and (D) a viscosity index improver, said lubricant composition having an HTHS viscosity at 150°C of 1.7-2.3 mPa·s and an HTHS viscosity at 100°C of 4.8 mPa·s or less. Thus, it is possible to provide a lubricant composition for an internal combustion engine that has good fuel-saving performance.
(FR) Cette composition lubrifiante pour moteur à combustion interne comprend (A) une huile de base lubrifiante, (B) du salicylate de magnésium, (C) du salicylate de calcium, et (D) un améliorant d'indice de viscosité, ladite composition lubrifiante ayant une viscosité HTHS à 150 °C de 1,7 à 2,3 mPa · s et une viscosité HTHS à 100 °C de 4,8 mPa · s ou moins. Ainsi, il est possible de fournir une composition lubrifiante pour un moteur à combustion interne qui a de bonnes performances d'économie de carburant.
(JA) （Ａ）潤滑油基油、（Ｂ）マグネシウムサリシレート、（Ｃ）カルシウムサリシレート、および（Ｄ）粘度指数向上剤、を含む内燃機関用潤滑油組成物であって、１５０℃のＨＴＨＳ粘度が、１．７以上２．３ｍＰａ・ｓ以下であり、１００℃のＨＴＨＳ粘度が、４．８ｍＰａ・ｓ以下である内燃機関用潤滑油組成物により、良好な省燃費性能を具備する内燃機関用潤滑油組成物を提供することができる。
