How to Select Viscosity Index Improvers: A Formulator's Guide

Pick the right viscosity index improvers for your blend. Compare OCP vs PMA vs HSD, understand SSI grades 23-55, and match polymer type to engine oil, ATF, or hydraulic fluid.

HTHS (High Temperature High Shear)

HTHS viscosity measures how engine oil behaves at 150°C under 10⁶ s⁻¹ shear — real bearing conditions, not a lab beaker. Covers ASTM D4683, SAE J300 grade-by-grade limits, and why cutting HTHS for fuel economy can cost you bearing protection.
