"The viscosity of binary liquid mixtures has been a subject of much investigation, but most of the work has been done with mixtures of substances other than lubricating oils. Lubricating engineers have found viscosity to be the most important property of a good lubricant, though up to the present time no one has succeeded in deducing a satisfactory expression by which the viscosity of a blended lubricant may be calculated from a knowledge of the physical properties of its components. This investigation has been an attempt to find a relationship between the absolute viscosity of a blended lubricating oil and the viscosities and relative numbers of molecules of its components" – Introduction, p. 1.
