Many years ago I attended a seminar on oils delivered by a representative from DX oils at an AACA annual meeting. Something he said has stuck with me for thirty years or more. When talking about off the shelf oil additives he said “The best result you can hope for with an additive is that it does no damage”. He reminded us that motor oil has been developed by chemical engineers and additives have already been added. Whatever you add in addition to the oil hasn’t been accounted for in the oil formulation. It is entirely possible that your additive will not be compatible with, and in fact counteract the additives in the motor oil. I’m not a chemical engineer. I will leave the oil formulation to someone at a higher pay grade. Zeke
