Abstract
A method and apparatus for measuring viscosity of an oil at low temperature and low shear stress. It employs a columnar container of the oil with vertically spaced temperature control devices to apply different cooling histories simultaneously. After the cooling histories have been applied, the viscosity of all the different histories is determined by measuring the instantaneous velocity of a probe moving through the column of oil under a constant force.
