I think you are overlooking the best feature of this oil--------the extra micro filtration process it goes thru--a VOA particle count would tell you if it is marketing, or a much cleaner oil right out of the bottle.
To see the special color you have to look with a black light. This is how oems can tell if you've changed the factory fill like you said you did, or not!
