  • Method for improving the fuel efficiency of engine oil compositions for large low and medium speed engines by reducing the traction coefficient
    Patent number: 8759267
    Abstract: The present invention is directed to a method for improving the fuel efficiency of low and medium speed engine oil compositions by reducing the traction coefficient of the oil by formulating the oil using at least two base stocks of different kinematic viscosity wherein the differences in kinematic viscosity between the base stocks is at least 30 mm2/s.
    Type: Grant
    Filed: January 28, 2011
    Date of Patent: June 24, 2014
    Assignee: ExxonMobil Research and Engineering Company
    Inventors: Kathleen H. Tellier, Vincent M. Carey, Kevin L. Crouthamel
  • Method for improving the fuel efficiency of engine oil compositions for large low and medium speed gas engines by reducing the traction coefficient
    Patent number: 8748362
    Abstract: The present invention is directed to a method for improving the fuel efficiency of large engine oil compositions by reducing the traction coefficient of the oil by formulating the oil using at least two base stocks of different kinematic viscosity wherein the differences in kinematic viscosity between the base stocks is at least 32 mm2/s, and, preferably, additizing the composition with a salicylate detergent, a mixture of salicylate-phenate detergents or a mixture of sulfonate and phenate detergents.
