Short answer: about 6 quarts (5.7 liters) of engine oil with a new filter.
In practice, the exact capacity can vary slightly by model year, drivetrain configuration, and whether an oil cooler is installed. The typical viscosity recommendation for this engine setup is 5W-30 with Dexos1 Gen 2 approval, but always confirm the specification for your specific vehicle in the owner's manual or from a GM dealer.

Maintenance tips: how to perform an oil change
Before listing the steps, note that the following guide reflects common practice for the 3.6 L V6 in this truck family. Use the recommended oil type and quantity for your exact year/model as stated in the manual.
- Warm up the engine briefly to loosen oil, then park on a level surface and engage the parking brake.
- Gather supplies: the correct amount of oil (about 6 quarts), a new oil filter, an oil filter wrench, a drain pan, a funnel, and gloves.
- Position the vehicle and safely lift the front end if needed to access the drain plug; place a drain pan underneath.
- Remove the drain plug and allow the old oil to drain completely; remove and replace the oil filter with a new one, ensuring a proper seal.
- Reinstall the drain plug, then add fresh oil through the engine oil fill port using a funnel until the dipstick indicates the correct level.
- Start the engine and run it for a minute to circulate oil, then stop and recheck the level; add more oil if needed to reach the full mark.
- Dispose of the used oil and filter properly according to local regulations.
Concluding: After a complete oil change, recheck the level with the engine warm and running for a moment, and reset any oil-change reminder if equipped.
