Motor oils are hardly designed for engines that are way off spec with whatever varied problem they might be afflicted with. (They are designed for newer or otherwise at least healthy cars.) Additives on the other hand are designed for some more specific applications. There are some unknown properties and there are makers of just snake oil too, so therefore if one can find testimonials and experiences posted online, then it could help make a better guess at choosing a product.
