As far as color of the oil after a given period of time in use, everyone has mentioned the various factors; engine condition, drive cycles, sludge in a neglected engine being removed, etc. What I haven't heard is that the discoloration is indictive of the contaminents being held in suspension.
Also take into consideration the coloring that the manufacturer adds to the oil so the consumer will have golden brown oil. The oil that is in my car right now is very dark right out of the bottle and has a ever so slight green tint. German Castrol Syntec 0w-30
