Does the Ford 2014Focus have a true oil monitor or just s a timer? I'm not interested on how often I should change oil or at what intervals are recommended by various experts or opinions. What I want to know is whether the 2014 Focus actually monitors the oil condition as to purity and contaminates and if those contaminates or oil integrity will trigger the change oil alert? Regardless of how often I drive the car or if I should not drive the car for long periods of time will the monitor tell me when the oil is due for a change based on the oil integrity and not just a timer. Again I'm not interested in experts recommended changes or oil age or type of oil other than manufacturers recommended type be it a blend or a synth. Thanks.
