2019–2025 Chevrolet Silverado maintenance schedule
Schedule type: oil-life monitor (GM Engine Oil Life System)
The truck calculates oil life from how it's driven and shows CHANGE ENGINE OIL SOON. Change the oil within 600 miles of the message and at least once a year. GM still wants a tire rotation and check every 7,500 miles. Extended idling counts as 33 miles per hour of idle. 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 2019; other years in this range are assumed to follow it. Confirm in your owner's manual.
