ABSTRACT:
An oil change sensing system for an internal combustion engine, having an oil pressure sensor adapted to provide an oil pressure signal to an engine control module; an oil temperature sensor adapted to provide an oil temperature signal to the engine control module; wherein the engine control module comprises an algorithm which determines the oil's viscosity by using the measured oil temperature and oil pressure and the determined oil viscosity and a fresh oil viscosity are used to determine whether the oil is in a preferred operating range.
