Comparative Viscosity Classifications

Notes
(1) Viscosity can only be related horizontally.
(2) Viscosities based on 95 VI single grade oils.
(3) ISO and AGMA viscosities are specified at 40oC.
(4) SAE 5W, 10W, 75W, 80W and 85W viscosities are specified at low temperature. Equivalent viscosities at 100oF and 210oF are shown.
(5) SAE 90-250 (Gear Oils) and SAE 20-50 (Engine oils) are specified at 210oF/99oC.
