  • Lubricating oil composition
    Patent number: 10000719
    Abstract: An automotive lubricating oil composition for an internal combustion engine comprises (A) an oil of lubricating viscosity in a major amount; and (B) an oil-soluble zinc dithiocarbamate as an additive component in a minor amount in which each of the two amino groups is substituted with an aryl group and with either another aryl group, an aliphatic group or a hydrogen atom, the composition having not greater than 1600 ppm by mass of phosphorus, expressed as phosphorous atom.
    Type: Grant
    Filed: August 17, 2012
    Date of Patent: June 19, 2018
    Assignee: INFINEUM INTERNATIONAL LIMITED
    Inventors: Joseph P. Hartley, Jonathan P. Flemming

  • Lubricating oil composition
    Patent number: 8455410
    Abstract: A crankcase lubricating oil composition for an internal combustion engine comprising (A) an oil of lubricating viscosity in a major amount; and, (B) as an additive component in a minor amount one or more, oil-soluble imides derived from a hydrogenated Diels-Alder adduct of a maleic anhydride and a furan, where the imide group has the formula >NR, where R is an aliphatic hydrocarbyl group having 4 to 8 carbon atoms.
