In the case of a ASHLESS 2 cycle oil yeah it would be a ashless dispersant or lousy base oil or dye but a normal cheapo spectro will NOT show much in that they show normally only ASH or metal addiitves.

That something else are the ashless additives, which will not show up on a VOA. You would have to have someone run a very expensive test to see them.
