- The Instron Capillary Rheometer, with special extremely fine capillaries, has been used to measure the apparent viscosities of non-Newtonian polymer-thickened multigrade oils at temperatures from 100¿̐ưF to 320¿̐ưF and shear rates to 106 sec¿̐ư1. The same apparatus can produce permanent shear under extreme conditions. Temporary shear data at 100¿̐ư, 150¿̐ư, 210¿̐ư, 280¿̐ư and 320¿̐ưF are reported for eight commercial oils and five experimental oils formulated with different VI improvers in the same base oil. Permanent shear data are given for a larger set of oils.
