Scheduled Maintenance Engine Oil Scheduled Maintenance Change engine oil and filter as indicated by the Engine Oil Life SystemR (or every 12 months, whichever occurs first). Reset the system. The system will show you when to change the oil -- usually between 3,000 miles (5 000 km) and 15,000 miles (25 000 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 15,000 miles (25 000 km) or 12 months without an oil and filter change. Use engine oil meeting the GM Standard GM4718M. The Engine Oil Life System won't detect dust in the oil. So if you drive in a dusty area, be sure to change your oil and filter every 3,000 miles (5 000 km) or sooner if the CHANGE OIL SOON message appears. Remember to reset the system when the oil and filter have been changed. See "Engine Oil Life System" in the Index for more information on resetting the system. An Emission Control Service. 7-6
