My 2 cents: If your idle oil pressure is so low your oil light is
flickering after high speed driving (and 75-80 is really pushing a flathead
six, especially if you don't have overdrive), I would run 20W50, which would
give you noticably better hot idle oil pressure, and (I think) an extra
margin of protection in high speed driving.
