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.
