My question was honest in the respect I wanted to see if you had actual data that supported your claim. The thixotropic agents added to oil to change viscosity as a function of temperature are polymers (haven't seen any MW data on them) that can or might have some shear sensitivity and break down into smaller molecules. This is mentioned by different sources but without any analysis that supports their assumption. It could just be assumptions or some hand waving.
