Abstract
The present invention is directed to a method for improving the fuel efficiency of engine oil compositions for large low, medium and high speed engines 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 mm/s, and additizing the composition with one or more detergents.
