2023 GMC Yukon Oil Capacity, Specs, and Filter Reference

The 2023 GMC Yukon takes 8.0 quarts (7.6 liters) of full synthetic 0W-20 oil for both the 5.3L and 6.2L V8 engines, while the 3.0L Duramax turbo-diesel requires 7.0 quarts (6.6 liters) of 0W-20 diesel-specific oil. As an ASE-certified master technician, I highly recommend checking your exact engine size on the under-hood emissions sticker or your owner's manual before starting the job, as using the correct oil specification is critical for modern engine longevity and warranty compliance.

Quick answer

For the standard gasoline V8 models (5.3L and 6.2L), here is exactly what you need for a complete oil change:

• Oil Capacity: 8.0 quarts (7.6 liters) with filter replacement.
• Recommended Weight: 0W-20 Full Synthetic.
• Oil Specification: GM dexos1™ Gen 3 (API SP).
• OEM Oil Filter: ACDelco PF63
• Aftermarket Filter Cross-Reference: Wix WL10390, Mobil 1 M1-113A, Fram Ultra XG12060 (or XG10575 depending on availability).

Capacity by engine option

The 2023 GMC Yukon is offered with three distinct powertrains. Always replace the oil filter when changing the oil to achieve these capacities.

(Note: The 3.0L Duramax requires a different filter: ACDelco PF66).

Oil change interval

Your 2023 Yukon is equipped with GM's Oil Life Monitor (OLM) system, which calculates oil degradation based on driving conditions. However, here are the real-world mileage rules you should follow:

• Normal Duty: Up to 7,500 miles, or when the OLM reads 10% or lower. Do not exceed 1 year without an oil change, regardless of mileage.
• Severe Duty (Towing, frequent short trips, extreme heat/cold, heavy idling): 5,000 miles. For the V8s, changing the oil every 5,000 miles is cheap insurance to protect the complex Dynamic Fuel Management (DFM) system.

Drain plug torque

• Torque Specification: 18 lb-ft (25 Nm).
• Washer Note: The factory drain plug utilizes an integrated rubber O-ring gasket. Inspect this O-ring carefully; if it is flattened, torn, or leaking, replace the entire drain plug. Do not overtighten, as the aluminum oil pans can strip easily.

How to change the oil

1. Preparation: Bring the vehicle up to operating temperature, then shut it off. Ensure the vehicle is parked on a level surface. Engage the parking brake. Use ramps or jack stands if you need extra clearance, though many Yukons sit high enough to slide under.
2. Drain the Oil: Remove the oil fill cap under the hood to help the oil drain faster. Locate the 15mm drain plug on the oil pan. Position a large catch pan (minimum 10-quart capacity) and remove the plug. Allow it to drain completely.
3. Replace the Filter: Move the drain pan under the oil filter. Use an oil filter wrench to remove the old filter. Wipe the engine's filter mounting surface clean with a rag. Lubricate the rubber gasket of the new filter with clean engine oil. Spin the new filter on by hand until the gasket makes contact, then tighten it an additional 3/4 to 1 full turn.
4. Reinstall Drain Plug: Reinstall the drain plug and torque to 18 lb-ft.
5. Refill: Add the required amount of 0W-20 oil (8.0 quarts for V8s, 7.0 quarts for the diesel). Reinstall the oil fill cap.
6. Verify and Reset: Start the engine and let it run for roughly 30 seconds to build oil pressure and fill the filter. Check underneath for any leaks. Turn the engine off, wait 5 minutes, and check the dipstick to confirm the level is at the "FULL" mark. Finally, navigate to the driver information screen using your steering wheel controls, find the Oil Life screen, and hold the thumbwheel to reset the monitor to 100%.

Common issues / tips

• V8 Lifter Health: The 5.3L and 6.2L V8 engines utilize Active/Dynamic Fuel Management (DFM). These systems rely on complex, oil-pressure-actuated lifters. Dirty oil or low oil levels are the primary causes of premature lifter failure on these engines. Stick strictly to the dexos1 Gen 3 specification and check your oil level at every fuel fill-up.
• Diesel dexosD Importance: If you have the 3.0L Duramax, you must use oil bearing the green dexosD logo. Standard gas-engine 0W-20 or older heavy-duty diesel oils will damage the emissions system and void your warranty.
• Messy Draining: On some 4WD models, oil draining from the filter can catch on crossmembers or skid plates. Form-a-funnel tools or a piece of cardboard can help route the oil directly into your pan and keep your driveway clean.
