Reply to "Are Viscosity Index Improver Polymers all that bad?"

TPaul:
Stay with your rationale as exposed along your first 2 paragraphs. Paradoxically, the purported advantage of multigrades easing cold starts is even more real at the higher than 100C temperature range! You can easilly see this in a log-log chart of viscosity and temperature, as you extrapolate the straight line trend further into the high temperatures.
