Oil loses additives and its ability to carry heat and debris before it necessarily looks dirty. Stop-and-go traffic, towing, and dust exposure can add operating demands, so drivers should respond to the oil-life reminder, low or dark dipstick reading, or louder startup engine note. Booking the visit records the service against the vehicle’s history.

The visit also includes a check of underhood fluid levels. Engine oil can lose its additive package and heat- and debris-carrying ability long before it appears dirty, which is why drivers should respond to maintenance reminders and changes in engine sound rather than relying only on appearance. The completed visit is logged against the vehicle’s history.

Because no manufacturer maintenance interval is stated for this model year, discuss the vehicle’s usage and service reminders with the team. Schedule service at Larry H. Miller Chrysler Dodge Jeep Ram Avondale, or call 480-207-2126.
