2019 GMC Sierra 1500 Oil Capacity & Filter Guide

The 2019 GMC Sierra 1500 requires between 6.0 and 8.0 quarts of oil, depending on the engine. For the most common 5.3L V8, you'll need 8.0 quarts of full synthetic 0W-20 oil that meets the dexos1 Gen 2 specification.

Quick Answer

• Recommended Oil Weight: SAE 0W-20 (5.3L & 6.2L V8) or SAE 5W-30 (4.3L V6)
• Oil Specification: dexos1® Gen 2 Full Synthetic
• Oil Filter (V8 Engines): GM/ACDelco PF63E
• Oil Filter Cross-Reference: Fram PH10575, Wix 57045, Mobil 1 M1-212A

Capacity by Engine Option

The 2019 model year was a transition, featuring both the new T1 platform and the outgoing K2 platform. Always verify your engine before purchasing supplies.

Oil Change Interval

Your 2019 Sierra is equipped with an Oil Life Monitoring (OLM) system. The system will display a "Change Engine Oil Soon" message when it's time for a service. However, the interval can vary based on your driving habits.

• Normal Duty: Follow the OLM, which will typically recommend an oil change every 7,500 to 10,000 miles or once a year, whichever comes first.
• Severe Duty: If you frequently tow heavy loads, idle for long periods, drive in dusty conditions, or make many short trips, you should change the oil more frequently, around every 3,000 to 5,000 miles.

Drain Plug Torque

The engine oil drain plug should be tightened to 18 lb-ft (25 Nm). Over-tightening can damage the threads in the aluminum oil pan, leading to costly repairs. Always use a new crush washer if the old one appears deformed to ensure a proper seal.

How to Change the Oil

Changing the oil on a 2019 Sierra is a straightforward process.

1. Run the engine for a few minutes to warm the oil.
2. Safely raise the vehicle using ramps or a jack and jack stands.
3. Place a drain pan under the oil pan and remove the 15mm drain plug.
4. While the oil drains, remove the oil filter. The V8 filters are located on the driver's side of the engine block and can be accessed from the wheel well.
5. Wipe the filter mounting surface clean and apply a thin layer of new oil to the gasket of the new filter.
6. Install the new filter and tighten it hand-tight plus an additional 3/4 turn.
7. Reinstall the drain plug with a new crush washer and torque it to 18 lb-ft.
8. Fill the engine with the correct amount and type of new oil.
9. Start the engine, let it run for 30 seconds, then shut it off and check for leaks.
10. Wait a few minutes, then check the oil level on the dipstick and top off if necessary.
11. Reset the Oil Life Monitor through the infotainment screen.

Common Issues / Tips

• Correct Filter is Crucial: The ACDelco PF63E filter specified for the V8 engines features a higher bypass valve rating required for the engine's variable-pressure oiling system. Using an incorrect filter (like the older PF48) can lead to inadequate lubrication and potential engine damage.
• AFM/DFM Lifter Noise: The 5.3L and 6.2L engines use Active Fuel Management (AFM) or Dynamic Fuel Management (DFM). Using the correct dexos1 Gen 2 certified 0W-20 oil is critical for the proper function of the hydraulic lifters involved in this system. Ticking noises on startup can sometimes be attributed to using the wrong oil viscosity or quality.
• Check Your RPO Codes: To be absolutely certain which engine you have, check the Service Parts Identification sticker in the glove box. The engine code (e.g., L84, L87) will be listed there.
