  • Alkylated phenoxathin base stock for lubricants
    Patent number: 5286396
    Abstract: Monoalkylated phenoxathins are high-temperature stable lubricant fluids having extreme pressure and antiwear properties, additive solubility and inherent EP/antiwear properties. These novel phenoxathin fluids may also be used as additives in other lubricant fluids and are prepared by alkyating a phenoxathin in the presence of an acidic zeolite catalyst.
    Type: Grant
    Filed: June 8, 1992
    Date of Patent: February 15, 1994
    Assignee: Mobil Oil Corporation
    Inventors: Leslie R. Rudnick, Carleton N. Rowe, Derek A. Law, G. Ali Naghipur
  • Reducing fuel consumption with a fluorinated compound
    Patent number: 4394134
    Abstract: Polymerizable (that is, e.g., monomeric) polyfluorinated compounds, when added to a lubricant or to a liquid hydrocarbon fuel, as for example gasoline, will cause a reduction in fuel consumption. Reduced fuel consumption may also be realized for long periods from pistons and/or cylinder walls so coated with one or more of the polymerizable compounds.
    Type: Grant
    Filed: November 9, 1979
    Date of Patent: July 19, 1983
    Assignee: Mobil Oil Corporation
    Inventor: Carleton N. Rowe
  • Lubricant composition containing a lubricity agent
    Patent number: 4167486
    Abstract: Lubricating oils containing olefin polymerizable acid esters and dimers and/or trimers thereof have been found to increase fuel economy in internal combustion engines. This is done by deposition of the additive on the lubricated surface.
    Type: Grant
    Filed: July 20, 1978
