Fuel economy and oxidation inhibition in lubricant compositions for internal combustion engines.

摘要

A friction-reducing lubricating oil composition and a method for reducing the fuel consumption of an internal combustion engine are disclosed. The lubricating oil composition comprises (a) a major amount of an oil having lubrication viscosity; (b) a minor amount of a friction-modifying, polar and surface-active compound; (c) a minor amount of a Group IA alkoli metal containing compound and (d) a minor amount of a transition element metal in a hydrocarbon-soluble or dispersible compound. The method for reducing fuel consumption of a spark-ignited internal combustion engine comprises utilizing an embodiment of the lubricating oil composition in the crankcase of the engine.
