Capacity by Engine Option

Oil Change Interval

Chevrolet recommends using the vehicle's Oil Life Monitoring System to determine when to change your oil. This system takes into account driving conditions, engine revolutions, and oil temperature to calculate optimal oil change intervals, which can vary significantly.

• Normal Duty: The Oil Life Monitoring System typically recommends oil changes every 7,500 to 10,000 miles or 12 months, whichever comes first.
• Severe Duty (e.g., frequent short trips, extreme temperatures, towing, dusty conditions): The system may recommend oil changes as frequently as 3,000 to 5,000 miles or 12 months, whichever comes first. It is crucial to monitor the system and not exceed one year between oil changes, regardless of mileage.

Drain Plug Torque

The oil drain plug for the 2015 Chevrolet Suburban 5.3L V8 engine should be torqued to 18 lb-ft (24 Nm). Always use a new drain plug gasket or crush washer to ensure a proper seal and prevent leaks. Most new oil filters come with a new crush washer.

How to Change the Oil

Changing the oil on your 2015 Chevrolet Suburban is a straightforward process:

1. Gather Supplies: New oil, new oil filter, drain pan, wrench for drain plug, oil filter wrench, funnel, rags, jack stands, and a jack.
2. Warm Up Engine (Slightly): Run the engine for a few minutes to warm the oil, allowing it to drain more easily. Do not let it get too hot.
3. Lift and Secure: Safely lift the front of the vehicle using a jack and support it with jack stands.
4. Locate Drain Plug: Place the drain pan under the oil pan, then remove the drain plug with a wrench. Allow all the old oil to drain completely.
5. Replace Drain Plug: Install a new crush washer on the drain plug and reinstall it, tightening to 18 lb-ft (24 Nm).
6. Remove Old Filter: Place the drain pan under the oil filter, unscrew the old oil filter using an oil filter wrench, and allow any remaining oil to drain.
7. Install New Filter: Apply a thin layer of new oil to the rubber gasket of the new oil filter. Screw it on by hand until snug, then tighten an additional 3/4 to 1 full turn (or according to filter manufacturer instructions).
8. Add New Oil: Lower the vehicle, remove the oil fill cap, and add 6.0 quarts of the recommended SAE 5W-30 oil using a funnel.
9. Check Level & Leaks: Start the engine and let it run for a minute, then shut it off. Wait a few minutes for the oil to settle, then check the dipstick and top off if necessary. Inspect for any leaks around the drain plug and oil filter.
10. Reset Oil Life Monitor: Consult your owner's manual for specific instructions on how to reset the Oil Life Monitoring System.

Common Issues / Tips

• Oil Consumption: Some 5.3L V8 engines from this era, particularly those with Active Fuel Management (AFM), can exhibit higher-than-normal oil consumption. Regularly check your oil level between changes and top off as needed to prevent engine damage. If consumption is excessive, consult a qualified technician.
• Active Fuel Management (AFM) / Dynamic Fuel Management (DFM): The 2015 Suburban's 5.3L V8 features AFM, which deactivates cylinders to save fuel. Ensure you are using the correct Dexos1 Gen2 (or newer) oil specification to provide proper lubrication to these components.
• Oil Filter Location: The oil filter is located on the driver's side, near the front of the engine, making it relatively accessible for DIY oil changes.
• Aftermarket "Catch Cans": Some owners install aftermarket oil "catch cans" in the PCV system to mitigate oil entering the intake manifold, a common side effect of direct injection and AFM systems. While not factory-recommended, this is a common modification among enthusiasts.
