Abstract: A method for improving friction reduction and fuel efficiency, while maintaining or improving wear protection, in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition comprising a lubricating oil base stock as a major component; and a detergent mixture comprising a first detergent having a TBN of less than about 100, and at least one other detergent different from said first detergent, as a minor component. The composition contains greater than about 4 weight percent of the first detergent, based on the total weight of the formulated oil. Friction reduction and fuel efficiency are improved and wear protection is maintained or improved as compared to friction reduction, fuel efficiency and wear protection achieved using a lubricating engine oil containing a detergent mixture having other than the first detergent having a TBN of less than about 100.

Abstract translation: 在通过使用配制的油作为润滑油的润滑油润滑的发动机中，提高摩擦降低和燃料效率的方法，同时保持或改善磨损保护。 配制油具有以润滑油原料为主要成分的组成， 以及包含TBN小于约100的第一洗涤剂和至少一种不同于所述第一洗涤剂的其它洗涤剂作为次要组分的洗涤剂混合物。 基于配制的油的总重量，组合物含有大于约4重量％的第一洗涤剂。 与使用含有TBN小于约100的第一洗涤剂以外的洗涤剂混合物的润滑发动机油进行摩擦降低，燃料效率和磨损保护相比，摩擦减少和燃料效率得到改善，并且保持或改进了磨损保护。

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 from 75 to 95 wt % of lubricating oil base stock including a Group I base stock or a combination of a Group III, Group IV and Group V base stock including from 30 to 35 wt % Group III, 45 to 55 wt % Group IV and 0 to 5 wt % Group V and a friction modifier mixture comprising a polymeric ethoxylated fatty acid ester at from 0.1 to 1.0 wt. % and a mixed glyceride ester at from 0.1 to 1.0 wt. % of the formulated oil. The lubricating engine oils are useful in internal combustion engines including direct injection, gasoline and diesel engines.
