Not sure where your located but plentifull around my area. The only critical thing is the jasco rating for wet clutches!! Most oil containers state whether wet clutch compatible. For year round use the 5w-40 is a good choice unless you have extreme cold well below 0.... Then a lighter weight like 0w - 20 etc can be used. I highly recomend a synthetic oil as thevthermal break down is far less than dino oil. Lots of folks run dino oil with no issues so your call. Stay with a popular brand and you will be fine.
