摘要：The present invention is directed to a method for improving the fuel efficiency
of large low and medium speed engine oil compositions by reducing the traction
coefficient of the oil by formulating the oil using a blend consisting of one or more GroupI base oils having a kinematic viscosity at 100° C. of from 2 to less than 12 mm/s incombination with a Group IV base oil having a kinematic viscosity of at least 38, thedifference in kinematic viscosity between the Group I and Group IV oils in the blend beingat least 30 mm/s in combination with a detergent.
