ABSTRACT:
This invention relates to a lubricating composition comprising a major amount of an oil of lubricating viscosity, (A) an antiwear improving amount of at least one molybdenum containing composition, (B) at least one phosphorus antiwear or extreme pressure agent, and (C) at least one dispersant, provided that the lubricating composition is free of polysulfurized olefins. The lubricating compositions have improved antiwear properties. When the lubricating composition is used in a manual transmission, the amount of brass wear is reduced.
