Get a used oil analysis whenever you decide to drain it.
I, for one, 'believe' in thin oil. It does exist and it does work, in its prescribed applications. I don't believe anyone suggested he use a thin oil. I'm assuming 5w-20 would be a thin oil, in this case. To be honest, I'm usually on the thin side of the argument when it's within recommendations or is the only recommendation but c'mon... OP has a 40+ year old car, he implies it burns at least some oil, and he lives in a tropical(?) climate. I think one, two, three strikes and he's probably going to be A-OK using 20w-50.
BITOG has taught me that color means next to nothing, unless it's a color like gray, then that means serious trouble. But in the case of it just turning dark fast, meh, I think you have nothing to worry about until a used oil analysis tells you otherwise.
