Capacity by Engine Option

Oil Change Interval

The 2020 Sierra is equipped with an Oil Life Monitor (OLM) that determines the oil change interval. It will illuminate a "Change Engine Oil Soon" message when it's time. This interval can be up to 7,500 miles, but varies based on your driving habits.

• Normal Duty: Follow the OLM. It will likely trigger between 5,000 and 7,500 miles.
• Severe Duty: If you frequently tow, idle for long periods, or drive in dusty/dirty conditions, expect the OLM to recommend an oil change sooner, typically every 3,000 to 5,000 miles.

Drain Plug Torque

• Drain Plug Torque: 18 ft-lbs (25 Nm)
• Crush Washer: It is highly recommended to replace the drain plug gasket at every oil change to prevent leaks. The OEM part number is 12616850.

How to Change the Oil

1. Run the engine for 2-3 minutes to warm the oil.
2. Place a drain pan under the oil pan drain plug.
3. Remove the plug and let the oil drain completely.
4. Re-install the drain plug with a new crush washer and torque to 18 ft-lbs.
5. Move the drain pan under the oil filter.
6. Remove the oil filter (some oil will spill).
7. Apply a light coat of new oil to the gasket of the new filter.
8. Install the new filter and tighten it one full turn after the gasket makes contact.
9. Fill the engine with the correct amount and type of oil.
10. Start the engine, let it run for 30 seconds, then shut it off and re-check the oil level, topping off as needed.
11. Reset the Oil Life Monitor.

Common Issues / Tips

For the 2019-2021 generation of Sierra 1500s, the most notable oil change-related tip is for the 5.3L and 6.2L V8 models. Some of these trucks feature a two-piece oil pan made of a cast-aluminum upper section and a stamped-steel lower section. The drain plug is on the lower section. Be careful not to overtighten the drain plug, as the stamped steel pan can be more prone to stripped threads than a traditional cast pan. Always use a torque wrench.
