2023 Ford Mustang maintenance schedule

Applies to: 2.3L EcoBoost and 5.0L V8 (GT, Mach 1), manual or 10-speed automatic (2023 Mustang coupe/convertible, not the Mach-E)

Schedule type: oil-life monitor (Intelligent Oil-Life Monitor)

Oil changes follow the Intelligent Oil-Life Monitor message. Ford says normal driving usually brings it at 7,000 to 10,000 miles, severe use at 5,000 to 7,500 and extreme use at 3,000 to 5,000. Never go more than 1 year or 10,000 miles between oil changes, and change it within two weeks or 500 miles of the message. Check the oil at every fill-up for track use or hard driving. 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 2023; other years in this range are assumed to follow it. Confirm in your owner's manual.
