More Information
Summary:Disclosed are Group III base stocks comprising at least 30 wt % naphthenes, a viscosity index from 120 to 145; and a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.
