2025 GMC Yukon Oil Capacity & Filter Guide

The 2025 GMC Yukon takes 8.0 quarts (7.6 liters) of 0W-20 oil for the 5.3L and 6.2L V8 engines, or 7.0 quarts (6.6 liters) of 0W-20 diesel-spec oil for the 3.0L Duramax inline-six. Getting the right oil capacity, viscosity, and filter for your full-size SUV is critical to keeping its engine running smoothly and maintaining your factory powertrain warranty.

Below is your complete ASE-certified guide to servicing the oil in your 2025 GMC Yukon.

Quick answer

Here are the vital specs for the most common 2025 GMC Yukon engines (5.3L and 6.2L V8):

• Oil Capacity: 8.0 quarts (7.6L) with filter change
• Recommended Weight: 0W-20
• Oil Specification: GM dexos1 Gen3 / API SP
• OEM Oil Filter: ACDelco PF63
• Aftermarket Filters: Fram PH10575, Wix WL10390, Mobil 1 M1-212A

(Note: If you have the 3.0L Duramax diesel, see the table below for your specific requirements.)

Capacity by engine option

The 2025 GMC Yukon is available with three different powertrains. Always verify which engine is under your hood before buying supplies.

Oil change interval

Modern GMC vehicles are equipped with an Intelligent Oil-Life Monitor (IOLM) system that calculates oil degradation based on engine temperatures, RPMs, and driving habits. However, we recommend the following baselines:

• Normal Duty: Every 7,500 to 10,000 miles, or when the Oil Life Monitor indicates, but at least once every 12 months.
• Severe Duty: Every 5,000 miles or 6 months. Severe duty includes frequent towing, extensive idling, driving in dusty conditions, or making mostly short trips under 5 miles where the engine never reaches full operating temperature.

For the 3.0L Duramax, adhering to severe duty intervals when towing heavy loads is highly recommended to protect the turbocharger and valvetrain.

Drain plug torque

• V8 Engines (5.3L / 6.2L): 18 lb-ft (25 Nm)
• 3.0L Duramax: 18 lb-ft (25 Nm)

Crush Washer Note: The factory drain plug uses a built-in rubber gasket. Inspect this gasket at every oil change. If it is torn, flattened, or leaking, you must replace the entire drain plug. If your drain plug utilizes a separate crush washer, replace the washer every single time you remove the plug to prevent leaks.

How to change the oil

1. Warm the engine: Run the vehicle for 3–5 minutes so the oil is warm and flows easily, then park on a level surface and engage the parking brake.
2. Access the drain plug: Place a large drain pan (at least 10-quart capacity) under the oil pan.
3. Drain the oil: Remove the 15mm drain plug. Allow the oil to drain completely.
4. Replace the filter: Locate the oil filter (front driver's side on the V8s, accessible from underneath). Remove the old filter, wipe the engine mating surface clean, and ensure the old rubber O-ring is not stuck to the engine block. Lubricate the new filter's O-ring with fresh oil and install it hand-tight (usually 3/4 to 1 turn past initial gasket contact).
5. Reinstall the plug: Install the drain plug and torque it to 18 lb-ft.
6. Fill the engine: Pour in the required amount of 0W-20 oil (8.0 qts for V8s, 7.0 qts for diesel) using a clean funnel.
7. Check levels and reset monitor: Start the engine, check for leaks underneath, and shut it off. Wait 5 minutes, then check the dipstick to confirm the level is correct. Finally, reset the Oil Life Monitor via the driver information screen on the dashboard.

Common issues / tips

• Dynamic Fuel Management (DFM): The 5.3L and 6.2L V8s use DFM cylinder deactivation technology, which relies heavily on precise oil pressure to operate the active lifters. Using the wrong viscosity or delaying oil changes can lead to premature lifter failure. Always stick to 0W-20 dexos1 Gen3.
• Filter Placement: On the V8 engines, the oil filter is located close to the front differential and crossmember. It is highly recommended to place a rag or a formed piece of cardboard under the filter housing before unscrewing it to prevent oil from dumping onto the steering components and frame.
• Duramax Oil Spec: Do not put standard gasoline-engine 0W-20 in the 3.0L Duramax. It specifically requires GM dexosD specification oil to handle diesel soot and protect the emissions system.
