Oil Change Interval

6.0L V8 Gasoline:

• Normal Duty: Every 7,500 miles or 12 months, whichever comes first.
• Severe Duty: Every 3,000-5,000 miles or 6 months, whichever comes first. Refer to your vehicle's Oil Life Monitor (OLM) for precise guidance.

Duramax 6.6L V8 Diesel:

• Normal Duty: Every 7,500 miles or 12 months, whichever comes first.
• Severe Duty: Every 5,000 miles or 6 months, whichever comes first. Heavy towing, frequent idling, or dusty conditions may warrant shorter intervals. Always consult the Oil Life Monitor (OLM) and your owner's manual.

Drain Plug Torque

• 6.0L V8 Gasoline: 18 lb-ft (24 Nm). Always use a new crush washer.
• Duramax 6.6L V8 Diesel: 37 lb-ft (50 Nm). Always use a new crush washer.

How to Change the Oil (General Steps)

1. Safely lift and support the front of the vehicle. Ensure it's level for accurate draining.
2. Place a suitable drain pan under the oil pan.
3. Remove the drain plug and allow the oil to drain completely.
4. Once drained, reinstall the drain plug with a new crush washer and tighten to the specified torque.
5. Locate and remove the old oil filter. Be prepared for some oil spillage.
6. Apply a thin film of new oil to the gasket of the new filter.
7. Install the new oil filter, tightening by hand until snug, then an additional 3/4 to 1 full turn (refer to filter instructions).
8. Lower the vehicle safely.
9. Remove the oil fill cap and add the recommended amount and type of fresh engine oil.
10. Reinstall the oil fill cap.
11. Start the engine and let it run for a few minutes. Check for leaks around the drain plug and filter.
12. Shut off the engine, wait a few minutes for the oil to settle, and then check the oil level on the dipstick. Add more oil if necessary to reach the "full" mark.
13. Reset the Oil Life Monitor.

Common Issues / Tips (2016 GMC Sierra 2500HD)

• Diesel Exhaust Fluid (DEF): For Duramax owners, remember that the 2016 model utilizes DEF. Ensure consistent DEF levels are maintained as it's crucial for emissions system operation. Never run out of DEF.
• Fuel Filter (Diesel): For Duramax engines, regular fuel filter replacement (typically every 20,000-25,000 miles or indicated by the maintenance reminder) is vital to protect the high-pressure fuel system.
• Oil Life Monitor (OLM): Do not solely rely on mileage for oil changes. The OLM in your Sierra 2500HD takes into account various operating conditions to accurately recommend when an oil change is due. Still, consider the severe duty intervals for heavy use.
• Crush Washers: Always use a new crush washer with the drain plug to prevent leaks. These are cheap and essential.
• Oil Cooler Lines (Gasoline): On the 6.0L V8, occasionally check for leaks around the oil cooler lines. This is a known area for potential seepage as vehicles age.
