Abstract
An engine oil system comprises an oil condition sensing device and a control module. The oil condition sensing device includes an electrically actuated member and is in fluid communication with an engine oil reservoir. The control module selectively causes current to be supplied to the oil condition sensing device to actuate the member, measures the current, determines a parameter of the current, and selectively identifies at least two of an oil level, an oil change event, and an oil viscosity level based on the parameter.
