That's not so bad. It may seem bad, but most consumer grade mongrades you come across here are just API SN, with nothing else. I'd suggest that a CF/SJ or something similar (which some of the oil companies still do provide here) would be more useful. I'm sure there's enough legacy farm equipment here to justify it, too, especially when some people stick to old specs.
Even when CF/SG was current (actually even before there was SG), my dad gave short shrift to monogrades. I suppose that living on a farm with no electricity (and therefore no block heaters or oil pan heaters) and an SAE 30 when the temperature went to -40 could very quickly sour one on the utility of monogrades.
