GM Oil Life Monitor

---

Standard on every Uplander model, the patented GM Oil Life Monitor helps take the guesswork out of when to change your vehicle's oil while also helping protect the environment from unnecessary oil changes. By tracking key engine operating parameters such as temperature, total number of revolutions, etc., the system predicts the vehicle's oil life and indicates when a change is necessary. See the Owner's Manual for more information. Maintenance needs vary with different uses and driving conditions.
