The dynamic simulations of non-equilibrium molecules of alkanes in the C20-C40 mass range, were presented, as this mass range form main constituents of lubricant basestocks, and hence their rheological properties are of great concern in industrial lubricant applicants. Simulation results obeyed corresponding states behavior as evidenced in the rheology of polymer melts. Through the generation of "master curve", for 9-octylheptadecane, this yielded the capability of quickly and efficiently predicting the Newtonian viscosity of lubricant components. Using low temperature shear thinning viscosity measurements at GPa pressures, for the first time, the consistency between simulation and experiment in the Newtonian and non-Newtonian regimes was demonstrated.
