Capacity by Engine Option

Oil Change Interval

Regular oil changes are vital for the longevity of your 2019 Chevrolet Silverado 2500HD. Always refer to your owner's manual for the most accurate and up-to-date information.

• Normal Duty: For most drivers under normal operating conditions, an oil change is recommended every 7,500 miles or 12 months, whichever comes first, for the gasoline engine. For the Duramax diesel, the oil change interval is typically 7,500 – 10,000 miles or 12 months, depending on usage and interpretation of the Oil Life Monitor (OLM).

• Severe Duty: If your driving habits fall under severe duty conditions (e.g., frequent towing/hauling, extreme temperatures, dusty conditions, extensive idling, short trips), you should consider more frequent oil changes. This could mean changing the oil every 3,000-5,000 miles or 6 months for the gasoline engine and 5,000-7,500 miles or 6 months for the diesel. Always pay attention to your vehicle's Oil Life Monitor (OLM) system.

Drain Plug Torque

Properly torquing the drain plug prevents leaks and avoids damaging the oil pan or plug threads. Always use a new crush washer with each oil change.

• 6.0L V8 Gasoline Engine:

  • Drain Plug Torque: 18 lb-ft (24 Nm)
  • Crush Washer: Refer to parts counter for correct size/type; often a flat aluminum or nylon washer.

• 6.6L V8 Duramax Diesel Engine:

  • Drain Plug Torque: 37 lb-ft (50 Nm)
  • Crush Washer: Refer to parts counter for correct size/type; often a metal gasket with a rubber coating.

How to Change the Oil

Changing the oil on your Silverado 2500HD is a straightforward maintenance task. Always ensure the vehicle is on level ground and safely supported before beginning.

1. Gather Supplies: New oil, new oil filter, drain pan, wrench for drain plug, oil filter wrench, funnel, rags, jack and jack stands (if needed).
2. Warm Engine (Optional but Recommended): Drive the truck for a few minutes to bring the oil up to operating temperature. This helps the oil drain more completely.
3. Locate Drain Plug: Place the drain pan under the oil pan. Use the appropriate wrench to loosen and remove the drain plug.
4. Drain Oil: Allow all the old oil to drain completely into the pan. This usually takes 10-15 minutes.
5. Replace Drain Plug: Install a new crush washer on the drain plug and thread it back into the oil pan. Torque to the specified value.
6. Remove Old Oil Filter: Place the drain pan under the oil filter and use an oil filter wrench to loosen and remove the old filter. Be prepared for a small amount of oil to spill.
7. Prepare & Install New Oil Filter: Apply a thin film of new engine oil to the gasket of the new oil filter. Thread the new filter into place by hand until snug, then turn an additional 3/4 to 1 full turn (or follow filter manufacturer's instructions).
8. Add New Oil: Using a funnel, carefully add the recommended amount and type of fresh engine oil through the oil filler cap.
9. Check Oil Level: Start the engine and let it run for a minute or two to circulate the new oil. Shut off the engine, wait a few minutes, then check the oil level with the dipstick. Add more oil if necessary until it reaches the "full" mark.
10. Dispose of Old Oil: Properly dispose of the used motor oil at a recycling center.

Common Issues / Tips

• Oil Life Monitor (OLM): The Silverado 2500HD uses an OLM system. While helpful, always consider your specific driving conditions. For severe duty, don't solely rely on the OLM; consider more frequent changes.
• Duramax Fuel Filter: On Duramax diesels, remember the fuel filter service is also crucial and generally recommended every 22,500 miles. Don't neglect it.
• Def/DPF Systems (Diesel): For the Duramax, using the correct low-ash CK-4 oil is critical to protect the Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR) systems. Incorrect oil can lead to premature DPF clogging and costly repairs.
• Oil Cooler Lines (Gasoline): On the 6.0L gasoline engine, keep an eye on the oil cooler lines at the front of the engine for leaks, especially as the vehicle ages. These are a known point of failure.
• Proper Oil Spec is Key: Ensure you are always using oil that meets the specified dexos1 (gasoline) or CJ-4/CK-4 (diesel) standards. Using non-compliant oil can void your warranty and lead to engine issues.
