If one oil has 150ppm Boron and say 55 Molly, but oil two only had 80 Boron and no Molly. All other areas in a VOA are much a like. Would the extra boron be a reason to pick?
Since organics that don't show in simple voa's can be used, I don't think you could make a decision on this alone. Gotta see the whole picture. What about ZDDP levels?
