Abstract:
1. A method for determining, in real time, the suitability of basestock oils for use as the basestocks in the production of fully formulated lubricating oils meeting product low temperature viscometric properties, which method comprises: (a) selecting at least one low temperature viscometric property of the fully formulated lubricating oil selected from mini-rotary viscometer (MRV) viscosity, yield stress, Brookfield viscosity, cold cranking simulator (CCS) and pour point, (b) producing a training set by: (c) subjecting a base oil to steps 1-8; (d) comparing the delta intensity of signal of the base oil of step (c) with the correlation data base to predict whether a formulated lubricating oil possessing the selected low temperature viscometric property or properties can be made using said base oil.
