I think we all have to face the fact that the most widely available motor 
oils are now formulated to work in modern engines, which have significantly 
different requirements than those of the air-cooled Corvair 
engine.  Fortunately, there are a lot of specialty lubricant manufacturers 
who still make suitable products.  It also pays to look around your local 
area. My neighborhood FLAPS has a selection of Amsoil and Brad Penn oils on 
the shelf...
