Applies to: Gasoline engines (3.6L V6 eTorque, 5.7L HEMI). The 3.0L EcoDiesel has a separate schedule and is not covered.

Schedule type: oil-life monitor (oil change indicator)

The truck tells you when the oil is due based on how it's driven, which can be as early as 3,500 miles in hard use. Never go past 10,000 miles, 12 months, or 350 engine hours. Get it done within 500 miles of the message. Summarized in our own words from the sources listed. Always follow the owner's manual or your dealer for your specific vehicle (VIN, engine, and options).

Checked against the official document for model year 2020; other years in this range are assumed to follow it. Confirm in your owner's manual.
