If you're mixing polar and non-polar base fluid, the first for additive solubility, does that mean the additives stay mainly in the polar component of the finished fluid? If that polarity also makes the polar fluid (and additves with them) attracted to metal surfaces, does that mean you get a higher additive concentration at those surfaces?
Are Viscosity Index Improvers also dependant on the solvency of the base fluids?
