Moreover, multivariable statistical analyses techniques have been used for predicting the pressure viscosity coefficient of lubricants using NMR experiments [13].
A number of studies have been carried out in the past on determining and establishing the dependency among different lubricant parameters since Barus established a relation between viscosity and pressure by introducing pressure viscosity coefficient "[alpha]" [14].
