ABSTRACT:
A device and method for measuring the quality of a vehicle oil change and the condition of oil obtained during an oil change is provided which includes an oil measurement compartment and at least one coolant sensor. The oil measurement compartment includes a conductivity sensor including a pair of horizontal parallel wires and a pair of vertical parallel wires which are capable of measuring the quantity, temperature, and conductivity of the drained oil. The coolant sensor is comprised of a hydrophilic material in contact with a permanent surface comprised of two spaced apart metal wires or traces. The coolant sensor measures the viscosity, coolant concentration, and overall condition of the oil.
