Capacity by Engine Option

Oil Change Interval

GM recommends following the Oil Life Monitoring System (OLMS) displayed in your vehicle's Driver Information Center (DIC). This system dynamically adjusts the oil change interval based on driving conditions, engine operating temperature, and other factors. However, general guidelines are:

• Normal Duty: Typically between 7,500 – 10,000 miles or 12 months, whichever comes first, as indicated by the OLMS.
• Severe Duty: If you frequently tow, drive in extreme temperatures, idle extensively, or drive in dusty conditions, the OLMS will likely recommend an oil change sooner, potentially around 3,000 – 5,000 miles.

It is crucial to never exceed 12 months between oil changes, regardless of mileage.

Drain Plug Torque

The engine oil drain plug for both the 5.3L V8 and 6.2L V8 engines on the 2021 GMC Yukon requires a torque of 18 ft-lbs (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 (Brief Steps)

1. Gather all necessary tools and supplies: new oil filter, 8 quarts of SAE 0W-20 Dexos 1 Gen 2 oil, drain pan, wrench for oil drain plug, oil filter wrench, torque wrench, and new drain plug crush washer.
2. Warm up the engine for a few minutes to allow the oil to flow more easily.
3. Park the vehicle on a level surface and engage the parking brake. For easier access, you may need to lift the front of the vehicle using a jack and secure it with jack stands.
4. Locate the oil drain plug on the engine oil pan. Place your drain pan directly underneath.
5. Carefully remove the drain plug and allow all the old oil to drain completely. This can take several minutes.
6. Once drained, reinstall the drain plug with a new crush washer and tighten it to 18 ft-lbs (24 Nm).
7. Locate the oil filter. Place the drain pan underneath it, as some oil will spill when removed.
8. Remove the old oil filter. Apply a thin coat of new oil to the gasket of the new oil filter.
9. Install the new oil filter by hand until snug, then tighten an additional ¾ to 1 full turn. Consult the oil filter packaging for specific tightening instructions.
10. Lower the vehicle if it was raised.
11. Remove the oil fill cap on top of the engine and slowly add the 8 quarts of new oil.
12. Reinstall the oil fill cap.
13. Start the engine and let it run for a few minutes. Check for any leaks around the drain plug and oil filter.
14. Turn off the engine and wait a few minutes for the oil to settle. Check the oil level on the dipstick and add more if necessary to reach the "full" mark. Do not overfill.
15. Reset the Oil Life Monitoring System in your vehicle.
