  • Patent number: 6652667
    Abstract: Disclosed are methods for removing engine deposits in a gasoline internal combustion engine by introducing a cleaning composition into an air-intake manifold of a warmed-up and idling gasoline internal combustion engine and running the engine while the cleaning composition is being introduced. One such cleaning composition suitable for these methods comprises (a) a phenoxy mono- or poly(oxyalkylene) alcohol; (b) at least one solvent selected from (1) an alkoxy mono- or poly(oxyalkylene) alcohol and (2) an aliphatic or aromatic organic solvent; and (c) at least one nitrogen-containing detergent additive.

  • Patent number: 6562765
    Abstract: An engine oil having a base oil and a friction reducing amount of an oil soluble sulfurized or unsulfurized oxymolybdenum complex prepared from reacting, in the presence of a polar promoter, an acidic molybdenum compound and a basic nitrogen compound and a low concentration of a sulfurized oxymolybdenum dialkyldithiocarbamate; employed together to provide at least 450 parts per million of molybdenum and less than 175 parts per million of molybdenum from the dialkyldithiocarbamate, both on the basis of the engine oil.
