Beschreibung
Zusammenfassung:	The invention provides a low deposition consumable engine oil composition saving fuel having excellent deposit resistance under high temperature more than 400 degrees centigrade and observably reducing the friction coefficient between metals. The low deposition consumable engine oil composition saving fuel is characterized that: the dynamic viscosity under 100 degrees centigrade is more than 4.5 mm2/s, and mineral oil with viscosity index more than 120 and/or amine antioxidant containing more than 1.5 mass % in total of synthetic oil and/or phenol antioxidant, and further containing more than 0.02 mass % of organic molybdenum compound measuring by molybdenum (Mo).
