Oil Life and Oil Life Start Value
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The oil life is displayed in percentages. The oil life start value is used to increase or decrease the starting point of the oil life. The oil life start value can be changed back to the maximum of approximately 16,093 km (10,000 miles) if the value was previously changed or to lower the value by 10% increments down to 10%. Each 10% reduction lowers the oil life in both mileage and time (days).
