Abstract
A method for improving fuel efficiency and reducing frictional properties, while maintaining or improving deposit control, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and a combination of (i) a friction modifier mixture and (ii) a detergent, as a minor component. Fuel efficiency and friction reduction properties are improved and deposit control is maintained or improved as compared to friction reduction properties and deposit control achieved using a lubricating engine oil containing a minor component other than the combination of the friction modifier mixture and detergent. A lubricating engine oil having a composition including a lubricating oil base stock as a major component, and a combination of (i) a friction modifier mixture and (ii) a detergent, as a minor component.
