PURPOSE: To obtain a composition having excellent emulsifying resistance and capable of keeping property as an engine oil and useful for a race necessitating high-performance. CONSTITUTION: A base oil of lubricating oil is mixed with a compound expressed by the formula: HO-(EO)1 -(PO)m -(EO)n -H (EO is ethylene oxide, PO is propylene oxide, (1), (m) and (n) are each integer and (EO)/(EO+PO) is 1-25wt.%) and weight-average molecular weight of 2,000-10,000 to obtain the objective oil composition for a 2-cycle engine. |
