20W-50's pretty popular from what I remember. It's what I've always used, only blew a couple cam seals, but I think that was a wear issue. My mechanic recommends always changing the oil after the winter, but you may not even have to bother if it doesn't get cold there, and you don't drive really early in the morning.
i cant tell you exactly about georgia because i dont know the weather there. But here in florida where it never goes below 70 in the winter, single wieght 40 is best. I used to be a Huge fan of the heavy duty 20w50 out of truck engines, in fact i was probly the one that started that trend goin around here, but i found out that single wieght oils take much longer to break down and the viscosity is always constant. So if the weather doesnt get to cold there go for single wieght 40. Its hard to find but its cheap.
