Oil loses additive performance and its ability to carry heat and debris over time, which is why mileage and time-based maintenance matter more than appearance alone. A reminder light, overdue mileage, dark or low dipstick oil, or a louder startup note can indicate that an inspection is appropriate. Towing and other demanding driving can also increase engine workload; the Grand Wagoneer L can tow up to 5,770 pounds across its seven trims.

Drivers in Avondale can schedule service online and have the completed visit logged against the vehicle’s history.

The service also includes a check of underhood fluid levels. That step helps identify a low fluid level that may need attention during routine maintenance.
