Capacity by engine option

Oil change interval

Chevrolet recommends changing the oil in your 2023 Suburban when the Oil Life Monitoring System indicates, typically around 7,500 miles (12,000 km) for normal driving conditions. However, under severe driving conditions, such as frequent short trips, sustained idling, towing, or extreme temperatures, the system may recommend an earlier change, potentially at 3,000-5,000 miles (4,800-8,000 km). Always follow the vehicle's oil life monitor for optimal engine longevity and warranty compliance.

Drain plug torque

For the 2023 Chevrolet Suburban with the 5.3L V8 (L84) and 6.2L V8 (L87) engines, the oil drain plug torque specification is 18 lb-ft (25 Nm). Always use a new drain plug washer (crush washer) with each oil change to ensure a proper seal and prevent leaks.

For the 3.0L Duramax I6 (LM2) engine, the oil drain plug torque specification is 22 lb-ft (30 Nm). A new drain plug washer should also be used with each oil change for this engine.

How to change the oil

1. Warm up the engine: Drive the vehicle for a few minutes to bring the oil to operating temperature, ensuring it drains more easily.
2. Lift and secure: Park on a level surface, engage the parking brake, and safely lift the front of the vehicle using a jack and secure it with jack stands.
3. Locate drain plug: Place a suitable oil drain pan beneath the oil pan.
4. Drain oil: Carefully remove the drain plug and allow all the old oil to drain completely. Inspect the old crush washer.
5. Replace drain plug: Install a new crush washer on the drain plug and reinstall the drain plug, tightening it to the specified torque.
6. Remove old filter: Move the drain pan under the oil filter. Loosen and remove the old oil filter. Be prepared for additional oil to drain out.
7. Prepare new filter: Apply a thin film of new oil to the rubber gasket of the new oil filter.
8. Install new filter: Thread the new oil filter on by hand until the gasket makes contact, then tighten an additional 3/4 to 1 full turn (or to manufacturer specifications, if different).
9. Fill with new oil: Lower the vehicle. Remove the oil cap and carefully add the recommended amount and type of new oil.
10. Check oil level: After filling, start the engine and let it run for a minute to circulate the oil. Turn off the engine, wait a few minutes for the oil to settle, and then check the oil level using the dipstick. Add more oil if necessary, but do not overfill.
11. Reset oil life monitor: Reset the oil life monitoring system according to your owner's manual instructions.

Common issues / tips

For the 2023 Chevrolet Suburban, particularly with the 5.3L and 6.2L V8 engines, maintaining the correct oil level and using the specified Dexos1 Gen3 0W-20 oil is crucial due to the Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) systems. These systems rely on oil pressure to actuate cylinder deactivation solenoids. Using the wrong oil viscosity or having low oil levels can lead to issues with these systems, potentially causing misfires, excessive oil consumption, or even engine damage over time.

For the 3.0L Duramax diesel, using the exact DexosD specification 0W-30 oil is paramount. Diesel engines have different lubrication requirements, and the DexosD spec ensures proper protection for the engine's components, including the sophisticated emissions systems.

Many owners choose to run a slightly shorter oil change interval than the maximum suggested by the oil life monitor, especially if they frequently do heavy towing or drive in dusty conditions, as added protection for these advanced engines. Regularly inspect for any signs of oil leaks around the drain plug and oil filter area after an oil change.
