Abstract of the Disclosure A system measures and records the API gravity the viscosity and the sulfur content of waxy lubricating oil and provides corresponding signals A computing circuit develops a signal corresponding to the wax content in accordance with the sensed parameter signals and the following equation. (1) W = C1 - C2A + C3? - C45 + C5A2-C6? + C7(A)(S) where C1 through C7 are constants and the preferred embodiment, when the temperature of the waxy oil being analyzed by a viscosity analyzer is substantially 210°F, has values of 51.17, 4.3135, 182.83, 5.2388, 0.101, 6.6106 and 0.19609; W is the wax content in weight percent, A is the API gravity of the oil and V is the kinematic viscosity of the oil in centistokes.
