(57) Abstract: [configuration] for 2-cycle engine lubricating oil composition of the present invention, the lubricant base oil, the following formulas (1) In formula (1) HO- (EO) l - (PO) m -(E O) n —H (wherein EO is ethylene oxide, PO is propylene oxide, l , m , and n are integers, and EO / (EO + PO) is 1% by weight to 25% by weight. ), A compound having a weight average molecular weight of 2,000 to 10,000 is blended. [Effect] The lubricating oil composition for a two-cycle engine of the present invention is excellent in anti-emulsification property and can maintain the performance as an engine oil, and is useful as a lubricating oil composition for high performance races. |
