How good are Motorcraft 10w/30 & 10w/40?

Lakeville, MN
Your best bet for getting the correct SL rated information is to get the data sheets for the Conoco Super All Season Motor Oil in the same grades. My VOA of the Conoco 5w20 showed it to be identical to the motorcraft 5w20 (which isn't a surprise since Conoco makes the Motorcraft lineup). Why the web page hasn't updated to the new SL specs is a mystery after this long!
