Engine Oil Additives Don't add anything to your oil.Your Cadillac dealer is ready to advise if you think something should be added. When to Change Engine Oil Your Cadillac has an "Oil Life Indicator." This feature will let you know when to change your oil-- usually between 3,000 miles (5 000 km) and 7,500 miles (12500 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 7,500 miles (12500 km) or 12 months without an oil change. The system won'tdetect dust in the oil. So, if you drive ina dusty area, be (5 m or sure to change your oil every 3,000 miles 000 k ) sooner if the "Change Oil Soon" light comes on. Remember to reset the Oil Life Indicator when the oil has been changed. For more information, see "Oil Life Indicator" in the Index.
