2024 Chevrolet Silverado 3500HD Oil Capacity & Filter Guide

Quick Answer

The 2024 Chevrolet Silverado 3500HD requires 6.0 quarts (5.7 liters) of 0W-20 engine oil for the 6.6L L8T gasoline engine, and 10 quarts (9.5 liters) of 15W-40 or 5W-40 engine oil for the 6.6L L5P Duramax diesel engine. In both cases, the oil should meet the appropriate OEM specifications.

• 6.6L L8T Gasoline Engine:

  • Oil Filter Cross-Reference: Fram XG12060, Mobil 1 M1-113A, Wix 57045

• 6.6L L5P Duramax Diesel Engine:

  • Oil Capacity: 10 quarts (9.5 liters)
  • Recommended Oil Weight: 15W-40 (preferred for most conditions) or 5W-40 (for colder climates or improved cold start)
  • Oil Specification: DexosD (consult owner's manual for specific Dexos revision)
  • Oil Filter OEM Part Number: 12706387 (ACDelco TP3006)
  • Oil Filter Cross-Reference: Fram CH12630, Wix 57602, Mobil 1 M1-213

Capacity by Engine Option

Oil Change Interval

The oil change interval for your 2024 Chevrolet Silverado 3500HD can vary significantly depending on driving conditions and engine type.

• Normal Duty: For standard driving conditions with regular highway use and minimal towing, the Engine Oil Life System (EOLS) is designed to inform you when an oil change is due. This is typically up to 7,500 miles or 12 months, whichever comes first.
• Severe Duty: If your truck is subjected to harsh conditions such as frequent short trips, extensive idling, dusty environments, consistent heavy towing, or extreme temperatures, the oil life will deplete faster. In these severe conditions, it is generally recommended to change your oil every 3,000-5,000 miles or every 3-6 months, or sooner if the EOLS indicates. For the Duramax diesel, heavy towing applications will also warrant more frequent changes.

Always consult your owner's manual and follow the vehicle's Engine Oil Life System (EOLS) for the most accurate oil change recommendations. The EOLS takes into account various operating conditions to determine the optimal interval.

Drain Plug Torque

Properly torquing your drain plug is crucial to prevent leaks and avoid damaging the oil pan threads.

• 6.6L L8T Gasoline Engine: The drain plug torque specification is 18 lb-ft (24 Nm). Always use a new drain plug crush washer with each oil change to ensure a proper seal. The OEM crush washer is typically aluminum or rubber-coated metal.
• 6.6L L5P Duramax Diesel Engine: The drain plug torque specification is 33 lb-ft (45 Nm). A new crush washer is also highly recommended for the Duramax to prevent leaks.

How to Change the Oil

Changing the oil on your 2024 Chevrolet Silverado 3500HD is a straightforward process for the DIY mechanic. Always ensure the engine is warm (but not hot) to allow the oil to drain more effectively, and use jack stands for safety if lifting the vehicle.

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. Access: Safely lift and support the front of the truck if necessary to access the drain plug and oil filter. For the Duramax, consider dropping the spare tire for easier access to the filter.
3. Drain Oil: Place the drain pan under the drain plug. Loosen and remove the drain plug and allow all the old oil to drain completely. Inspect the old crush washer.
4. Replace Drain Plug: Install a new crush washer on the drain plug and reinstall 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 oil filter. Be prepared for some oil to spill.
6. Install New Oil Filter: Apply a thin film of new oil to the gasket of the new oil filter. Screw on the new filter by hand until it seats, then tighten an additional 3/4 to 1 full turn (or as per filter manufacturer instructions). Do not overtighten.
7. Add New Oil: Using a funnel, slowly add the recommended amount and type of new oil to the engine through the oil filler cap.
8. Check Level: After adding the oil, start the engine and let it run for a minute to circulate the new oil. Then, shut off the engine and wait a few minutes for the oil to settle. Check the oil level on the dipstick and add more if needed to reach the "FULL" mark. Do not overfill.
9. Dispose: Properly dispose of used oil and filter at an approved recycling center.

Common Issues / Tips for This Generation

• Duramax Diesel Fuel Filter: For Duramax owners, it is critical to also change the fuel filter regularly, often every 15,000-20,000 miles, or as indicated by the maintenance reminder system. This is separate from the oil change but equally vital for engine longevity.
• DEF System Maintenance: The Diesel Exhaust Fluid (DEF) system on Duramax models requires periodic refills. Pay attention to warnings and maintain proper DEF levels to avoid derating engine power. Always use high-quality, approved DEF.
• Oil Life Monitor Accuracy: While the EOLS is generally accurate, active drivers who frequently tow or operate in severe conditions may consider slightly shorter intervals, especially for the Duramax, as a preventative measure.
• Proper Oil Specification: Always double-check your owner's manual for the latest Dexos specifications (e.g., Dexos1 Gen3 for gasoline, DexosD for diesel) as these can be updated by GM. Using the correct specification is crucial for warranty compliance and engine protection.
• Check for Leaks: After any oil change, always check thoroughly for leaks around the drain plug and oil filter. A small drip can become a big problem.
