ABSTRACT:
A detection device having pushbutton operation which after a short predetermined period of time indicates by means of lights whether both oil and lubricant levels are adequate or if not which is not satisfactory. The device is coupled with circuitry so as to quickly activate a thermistor within the lubricant reservoir for accurate detection at that point and may be coupled with engine deactivation means to preclude engine operation in the event that the device is not activated or in the event that either of the coolant or lubricant levels are inadequate.
