2021 Ram ProMaster maintenance schedule

The factory schedule for normal driving. Oil changes follow the oil-change indicator on most models; severe use (towing, dusty roads, lots of idling) shortens some intervals.

A dot means the service is due at that mileage or after that many years, whichever comes first. Engines: see schedule title.
