ABSTRACT:
A lubricating oil composition for two-stroke cycle cylinder injection engines contains as essential ingredients: (A): a base oil containing (1) 10-30% by mass of polybutene with number-average molecular weight 250-350 on the basis of a total amount of the base oil, (2) 30-60% by mass of polybutene with number-average molecular weight 450-550 on the basis of the total amount of the base oil, and (3) 15-40% by mass of mineral oil and/or a synthetic oil, which is other than polybutene, with kinematic viscosity 2-35 mm.sup.2 /s at 100.degree. C., on the basis of the total amount of the base oil; and (B): 2-15 parts by mass of alkylaminophenol having an alkyl group with 8-400 carbon atoms relative to 100 parts by mass of the base oil.
