COMPOSITION FOR ADDING TO GASOLINE

摘要

PURPOSE:To obtain the subject composition extremely reducing accumulation especially to the suction valve of automobile engine, comprising an organopolysiloxane and a lubricating oil component having a specific viscosity as principal components. CONSTITUTION:The objective composition contains (A) an organopolysiloxane expressed by the formula [R is 1-18C (halogenated)hydrocarbon; (n) is integer of 0-50] and preferably having <=50mm<2>/S viscosity at 25 deg.C and (B) a paraffin- based and/or naphthene-based lubricating oil having 3-35mm<2>/S viscosity at 100 deg.C as principal components.
