ABSTRACT:
A method and apparatus is provided for determining decreases and increases of viscosities of used oils or fluids and to detect changes in the oils or fluids during operation in equipment or storage. The limits on both ends can be established by the individual user to meet his or her own specification. Also, the standards can be prepared in a laboratory using various amounts of lesser and higher viscosity oils or fluids to attain the minimum and maximum limits required. There is provided three cups having holes or apertures in the lower end and wherein the holes or apertures are of different sizes, and wherein the cups are adapted to be moved into engagement with containers having oil or fluid therein, and then the cups are raised or immersed to permit the oils or fluids to drain through the holes to accomplish the desired results.
