I emailed Warren Distribution about the discrepancies in additive chemistries between what the data sheets for Supertech High Mileage state for additives, and what PQIA's VOA shows. The data sheets show high calcium and boron. PQIA shows modest calcium and high sodium.
According to Dietz Brock at Warren Distribution the additives used at the Iowa plant and the West Virginia plant are different, but meet the same certifications. A WPP product does have different additive chemistry than a WNE product. We in the Northeast get the WNE product with the calcium and sodium additive package that is bottled in the West Virginia plant.
