Scheduled Maintenance NORMAL SCHEDULED MAINTENANCE AND LOG 313 Intelligent Oil-Life Monitor® - 3.7L and 5.0L Engines Your vehicle is equipped with an Intelligent Oil-Life Monitor® that determines when the engine oil needs to be changed based on how your vehicle is used. By using several important factors in its calculations, the monitor helps reduce the cost of owning your vehicle and reduce environmental waste at the same time. This means you won't have to remember to change the oil on a mileage-based schedule; the vehicle lets you know when an oil change is due by displaying OIL CHANGE REQUIRED in the information display. The following table is intended to provide examples of vehicle use and its impact on engine oil change intervals; it is provided as a guideline only. Actual engine oil change intervals depend on several factors and generally decrease with severity of use. Note: The Shelby® GT500® information display is NOT equipped with this feature. Refer to your Shelby GT500 supplement for oil change service intervals.
