Capacity by engine option

Oil change interval

6.0L Vortec V8:

• Normal Duty: The Silverado's Oil Life Monitoring (OLM) system should be followed, typically indicating a change between 7,500 and 10,000 miles or 12 months, whichever comes first.
• Severe Duty: If you frequently tow heavy loads, drive in extreme temperatures, idle extensively, or drive in dusty conditions, the OLM may recommend an oil change sooner, potentially between 3,000-5,000 miles. It is always best to adhere to the OLM notification.

6.6L Duramax V8:

• Normal Duty: Follow the Oil Life Monitoring (OLM) system, which generally recommends an oil change between 7,500 and 12,000 miles or 12 months, whichever comes first.
• Severe Duty: For vehicles regularly towing heavy loads, operating in extreme heat or cold, or used for commercial purposes, the OLM will trigger an oil change sooner, often around 5,000-7,500 miles. Using synthetic diesel oil can extend the life, but always rely on the OLM.

Drain plug torque

• 6.0L Vortec V8: The oil pan drain plug torque specification is 18 lb-ft (24 Nm). Always use a new drain plug gasket or crush washer to prevent leaks.
• 6.6L Duramax V8: The oil pan drain plug torque specification is 33 lb-ft (45 Nm). A new crush washer should always be used with each oil change.

How to change the oil

1. Warm the Engine: Drive the truck for a few minutes to bring the oil up to operating temperature, ensuring it drains more easily. Safely park on a level surface.
2. Locate Drain Plug: Place a drain pan under the oil pan. For the 6.0L, remove the 15mm drain plug. For the 6.6L Duramax, remove the 13mm drain plug.
3. Drain Oil: Allow all the old oil to drain completely. This can take 10-15 minutes.
4. Replace Drain Plug: Install a new crush washer on the drain plug and re-install it, tightening to the specified torque.
5. Remove Oil Filter: Position the drain pan under the oil filter. Use an oil filter wrench to loosen and remove the old filter. Be prepared for a small amount of oil to spill.
6. Prepare New Filter: Apply a thin film of new oil to the gasket of the new oil filter.
7. Install New Filter: Hand-tighten the new oil filter until the gasket makes contact, then turn an additional 3/4 to 1 full turn. Do not overtighten.
8. Add New Oil: Remove the oil fill cap and add the recommended amount and type of new oil.
9. Check Level & Leaks: Start the engine and run for a minute to circulate the oil. Shut off, wait a few minutes, then check the oil level with the dipstick. Add more oil if needed. Also, check for any leaks around the drain plug and oil filter.

Common issues / tips

• Duramax LML Fuel Injector Return Lines: The Duramax LML engine is known for occasionally having issues with fuel injector return lines developing leaks over time. While not directly oil-related, a fuel leak near the engine can sometimes be confused with an oil leak or affect engine performance, especially if the fuel dilutes the oil. Regular inspection during oil changes is a good idea.
• 6.0L Vortec AFM/DOD System: The 6.0L Vortec V8 uses Active Fuel Management (AFM) or Displacement on Demand (DOD), which deactivates cylinders for improved fuel economy. This system can be prone to lifter failures, especially if oil change intervals are neglected or improper oil is used. Using Dexos1 Gen2 (or Gen3) specified oil and adhering to the OLM is crucial for the longevity of AFM components.
• Oil Life Monitoring (OLM) System: Trust the OLM system. It's a sophisticated algorithm that takes into account various factors like engine revolutions, temperature, and driving conditions to determine when an oil change is truly needed. Don't simply rely on mileage alone.
• Aftermarket Filters: While the listed aftermarket filters are popular, ensure any substitute filter meets or exceeds OEM specifications for filtration efficiency and construction. Cheaper, lower-quality filters can lead to premature engine wear.
