The Viscostick provides information whether the viscosity has increased or decreased. Typically it will detect 5-10% fuel dilution as well as increases in viscosity due to oil contamination like water. It can not be used to get an actual viscosity value but you will get an idea whether the viscosity is greater or smaller than the viscosity of the reference oil. It is essential that both oils have the same temperature at the time of the measurement.
