Capacity by Engine Option

The 2023 model year offered two distinct engine choices, each with a different oil and filter requirement. It is critical to use the correct fluid and parts for your specific engine to ensure longevity and proper performance.

Oil Change Interval

Your truck is equipped with the GM Oil Life Monitoring (OLM) system, which should be your primary guide for scheduling oil changes. The system calculates the ideal interval based on mileage, engine hours, and driving habits.

• Normal Duty: For most drivers, the OLM will recommend an oil change every 7,500 to 10,000 miles. This typically involves highway driving with minimal loads.
• Severe Duty: If you frequently tow heavy trailers, haul large payloads, operate in dusty or off-road conditions, or engage in excessive idling, the OLM will shorten the interval accordingly, often to between 3,000 and 5,000 miles. Duramax owners who tow should be especially vigilant about following the severe duty schedule.

Drain Plug Torque

Properly tightening the oil drain plug is essential to prevent oil leaks and avoid stripping the threads in the oil pan.

• Drain Plug Torque Spec: 18 lb-ft (25 Nm)
• Crush Washer: Always use a new crush washer on the drain plug with every oil change to ensure a perfect seal. Do not reuse the old washer.

How to Change the Oil

Changing the oil on your Silverado 2500HD is a straightforward process for a DIYer with the right tools. This is a general guide; consult a detailed service manual for your specific engine.

1. Warm the engine for 2-3 minutes to allow the oil to flow easier.
2. Position a drain pan under the oil pan and remove the drain plug.
3. While the oil is draining, locate and remove the old oil filter. Be prepared for some oil spillage.
4. Wipe the filter mounting surface clean and apply a thin layer of new oil to the gasket of the new filter.
5. Install the new oil filter and tighten it three-quarters to one full turn after the gasket makes contact.
6. Once the old oil has fully drained, reinstall the drain plug with a new crush washer and torque it to 18 lb-ft.
7. Refill the engine with the correct amount and type of oil.
8. Start the engine, let it run for 30 seconds, then shut it off. Wait a minute for the oil to settle, then check the dipstick and add oil if necessary. Check for any leaks around the plug and filter.
9. Reset the Oil Life Monitor through your vehicle's infotainment screen.

Common Issues / Tips

• Confirm Engine Type: Before buying supplies, double-check whether you have the gas or diesel engine. They use completely different oil and filters.
• Duramax Capacity: The 10-quart capacity of the Duramax is substantial. Ensure you have enough oil on hand and a large enough drain pan to handle the volume.
• Reset the OLM: Forgetting to reset the Oil Life Monitor is a common mistake. If it’s not reset, it will not accurately predict your next required service.
• Dipstick is King: The stated oil capacity is a reference. Always use the dipstick for the final, accurate fill level. Add the final quart slowly to avoid overfilling.
