EUROPEAN ACTIVITY CONCERNING ENGINE OIL VISCOSITY CLASSIFICATION--PART IV-THE EFFECTS OF SHEAR RATE AND TEMPERATURE ON THE VISCOSITY OF MULTIGRADE OILS

Three mathematical models have been used to correlate over a thousand high-shear-rate viscosity data generated by CEC Committee CL-23 on multigrade reference oils, using shear rates up to 16000/s at 25 degrees C and up to 1300,000/s at 150 degrees C. The work has established that all three models provide a good fit for the data and that there is little difference between their precisions of fit. The constants found by fitting the three models to the high-shear-rate viscosities of fifteen multigrade reference oils of special interest to the CEC and the SAE/ASTM are recorded for future use.
