Capacity by Engine Option

Oil Change Interval

For the 2022 model year, GM relies on the vehicle's Oil Life Monitoring (OLM) system to determine the appropriate oil change interval. However, the owner's manual provides guidance for "Normal" and "Severe" duty cycles.

• Normal Duty: Follow the OLM, which will typically recommend an oil change every 7,500 to 10,000 miles.
• Severe Duty: Change the oil every 3,000 to 5,000 miles. Severe conditions include frequent towing, extensive idling, driving in dusty or off-road environments, or making frequent short trips in extreme temperatures.

Drain Plug Torque

• Drain Plug Torque Spec: 18 lb-ft (25 Nm) for both gasoline and diesel engines.
• Crush Washer: Always use a new crush washer to prevent leaks. Consult your dealer for the correct part number.

How to Change the Oil (Simplified)

1. Run the engine for 2-3 minutes to warm the oil.
2. Position a drain pan under the oil pan and remove the 15mm drain plug.
3. Allow the oil to drain completely.
4. While draining, remove the oil filter. Be prepared for some oil spillage.
5. Lubricate the gasket of the new filter with fresh oil and install it hand-tight, plus an additional 3/4 to one full turn.
6. Reinstall the drain plug with a new crush washer and torque to 18 lb-ft.
7. Fill the engine with the correct amount of new oil.
8. Start the engine, let it run for a minute, then shut it off. Wait a few minutes and re-check the oil level, topping off as needed.
9. Reset the Oil Life Monitor through the infotainment screen or driver information center.

Common Issues / Tips

• Correct Viscosity is Critical: The L8T V8 gasoline engine specifically requires a dexos1 Gen 3 rated 0W-20 oil. Using a heavier weight oil can affect the performance of the variable valve timing (VVT) system.
• Diesel Fuel Dilution: The 6.6L Duramax L5P, like many modern diesels, can experience minor fuel dilution in the oil due to the DPF regeneration process. If you notice a rising oil level or smell fuel on the dipstick, it may be time for an early oil change. This is more common with frequent short trips where the engine doesn't reach full operating temperature.
• Filter Access: On the gasoline V8, the oil filter is located on the side of the oil pan and is relatively easy to access. On the Duramax diesel, the filter is mounted higher up and can be messy to remove; having a good filter wrench and plenty of shop towels is recommended.
