The 50% boiling point, the gravity and the viscosity of waxy oil are sensed by sensors which provide corresponding signals. A computing circuit connected to the sensors provides a signal corresponding to the wax content of the waxy oil in accordance with the signals from the sensors and equations hereinafter disclosed.

Means for measuring the wax content of waxy oil

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 an equation hereinafter disclosed. The wax content signal is recorded.
