Oil Maintenance and Service Tips
Checking Oil Level
Check engine oil level monthly when the engine is cold and on level ground. The oil level should register between the minimum and maximum marks on the dipstick. Add oil in small increments if the level is low to avoid overfilling.
Oil Change Best Practices
Change engine oil every 7,500 miles or 12 months under normal driving conditions. Always replace the oil filter during each oil change to maintain proper filtration. Use only oil meeting GM dexos1 Gen 2 specifications to ensure warranty compliance.
Severe Driving Conditions
Reduce oil change intervals to every 5,000 miles for severe driving conditions including frequent short trips, towing, dusty environments, or extreme temperatures. Monitor the oil life monitoring system for accurate service intervals. Severe conditions accelerate oil degradation and require more frequent maintenance.
Oil Drain Plug Torque
Torque the oil drain plug to 18 lb-ft (24 N·m) to prevent leaks or damage. Use a torque wrench for accurate tightening rather than over-tightening by hand. Replace the drain plug gasket if specified by the manufacturer.
