Summary:This lubricating oil composition for a four stroke engine contains a base oil (A) and 0.5-10 mass% of a polyolefin (B) which has at least constituent units derived from isobutene and which has a number average molecular weight of 500-10,000. The lubricating oil composition has a sulfated ash content of 0.3-1.2 mass%. Cette composition d'huile lubrifiante pour un moteur à quatre temps contient une huile de base (A) et 0,5 à 10% en masse d'une polyoléfine (B) qui a au moins des unités constitutives dérivées de l'isobutène et qui a une masse moléculaire moyenne en nombre de 500 à 10'000. La composition d'huile lubrifiante a une teneur en cendres sulfatées de 0,3 à 1,2% en masse. 本発明の4サイクルエンジン用潤滑油組成物は、基油(A)と、少なくともイソブテン由来の構成単位を有し、かつ数平均分子量が500~10,000であるポリオレフィン(B)0.5~10質量%とを含み、硫酸灰分が0.3~1.2質量%である。
