You do realize that 20-50 weight oil is NOT the same as straight 50 weight oil. I have always run 20-50, lately Brad Penn oil (Now renamed to Penn/Grade) in my CJ with an AMC 360 in it. If I lived where 0* was common in the winter time it would be a different story.
Arguments are all over the place when it comes to oil. I like it thicker than some folks. My belief is that the thicker oils cushion the bearings better than the thin stuff. Others like thin oils because it moves faster through the engine removing heat and sludge more efficiently. Lumpy has a point, emotion plays a big roll in the oil discussion.
I also believe that oils have advanced quite a bit over the years. I remember when 10-40 was the hot ticket, everybody used it. Suddenly !0-40 is a no no. 10-30 is supposed to be better. Now 5-15 or one of the other light oils are preferred.
