Abstract

"Of all the properties required of a good lubricant the most important is that of the viscosity at the temperature of its use. Most lubricants consist of oils blended or compounded together in such a way as to produce an oil of a desired viscosity, falling in the special group of viscosities expressed by the Society of Automotive Engineers in their tabulations.

There have been several methods developed to enable the refiner to blend quickly and efficiently although Bell stated that the methods were largely that of trial and error. Herschel formed a chart for blending by the logarithmic rule of volume percentage. This was based on a chart devised by Espy, the calculations being based on the logarithmic function of the volume percent of the component oils. This method had been suggested by Arrhenius and proved to be erroneous by Reyer, Dunstan and Thole, and Kendall and Monroe. Charts showing corrections to be applied were devised from data obtained from 25, 50 and 75 percent blends.

The investigation herein described has been based largely on the work of Epperson and Dunlap in an effort to justify the application of the mol fraction-cube root viscosity equation of Kendall and Monroe to the blending art"--Introduction, page 1.
