Abstract
The antifriction properties of a lubricating oil are enhanced by the addition of a minor amount of an oil-soluble molybdenyl bis-.beta.-diketonate. The antifriction properties are particularly enhanced when the molybdenyl bis-.beta.-diketonate is used in combination with an oil-soluble active sulfur donor, such as a zinc dialkyldithiophosphate.
