The Chevy Tahoe has a feature that displays an Oil Life Remaining percentage that helps you know when to change your oil. For example, if “REMAINING OIL LIFE 80%” is displayed, that means 80% of the current oil life remains.
Once the Remaining Oil Life hits a low percentage, a message that says “CHANGE ENGINE OIL SOON” will be displayed.
You can reset the Oil Life on your 1998 to 2021 Chevy Tahoe using these steps.
