Oil Maintenance and Service Tips
Regular oil changes are critical for maintaining engine health and preventing premature wear. The Cadillac XT6 oil change interval is every 7,500 miles or 6 months under normal driving conditions. Severe driving conditions include frequent short trips, extended idling, towing, dusty environments, or extreme temperatures.
Always use dexos1-approved full synthetic oil to maintain warranty coverage and ensure proper engine protection. Check the oil level monthly by parking on level ground, waiting for the engine to cool, and using the dipstick to verify the level is between the minimum and maximum marks. When performing an oil change, always replace the oil filter and torque the drain plug to 18 lb-ft (24 N·m) to prevent leaks.
ACDelco dexos1 and Mobil 1 Advanced Full Synthetic are approved oils that meet GM specifications. Reset the oil life monitor after each oil change through the vehicle information center. Never extend oil change intervals beyond the manufacturer recommendations, as degraded oil loses its protective properties.
Normal vs. Severe Driving Conditions
| Driving Type | Oil Change Interval | Examples |
|---|---|---|
| Normal Driving | Every 7,500 miles or 6 months | Highway commuting, moderate temperatures |
| Severe Driving | Every 5,000 miles or 4 months | Frequent short trips, towing, extreme heat or cold, dusty conditions |
