   Same way you compare any two oils.  Viscosity breakdown with time,   
   viscosity curve with temperature, adhesion, solvent characteristics,   
   ability to keep particulates in solution, three-ball test, etc.   
      
   There are standards for all this stuff and in general the European   
   standards are tighter than the US ones.  It's interesting to look across   
   a given line... for example, the Castrol Syntec 10W-40 meets the latest   
   European standards but the 10W-30 and 10W-50 formulations do not.
