Complete Oil Specifications
Your 2024 GMC Yukon XL 5.3L V8 requires 0W-20 oil certified to GM dexos1 Gen3. The L84 EcoTec3 uses Active Fuel Management (AFM) — a cylinder deactivation system that switches between 4- and 8-cylinder operation under light load. dexos1 Gen3 includes specific additive chemistry that supports AFM valve lifter health and provides Low-Speed Pre-Ignition (LSPI) protection.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| GM Approval | GM dexos1 Gen3 (API SP) |
| Capacity (with filter) | 8.0 quarts |
| Oil Filter | ACDelco PF64 |
| Normal Interval | 7500 miles (OLM) |
Why dexos1 Gen3 / 0W-20 is Critical for This Engine
The L84 5.3L V8 features AFM (Active Fuel Management) which hydraulically deactivates four cylinders at light load. The AFM lifter solenoids require an oil that can rapidly change pressure to collapse and re-extend the variable lift lifters. dexos1 Gen3’s specific friction modifier and viscosity profile ensures the AFM system responds correctly in all temperature conditions.
dexos1 Gen3 (introduced 2021) adds LSPI protection requirements — critical for the L84 which uses direct injection alongside port injection in some operating modes. It also improves oxidation stability for the extended OLM-guided intervals.
Using non-dexos oil or dexos1 Gen2 (or older) will:
- ❌ Potentially cause AFM lifter collapse errors, leading to excessive AFM valve noise
- ❌ Provide inadequate LSPI protection in GDI operating modes
- ❌ Void GM’s oil change interval coverage under warranty
GM-Approved Oil Brands
-
✅ ACDelco dexos1 Gen3 0W-20
-
✅ Mobil 1 dexos1 0W-20
-
✅ Pennzoil Platinum dexos1 0W-20
-
✅ Castrol Edge dexos1 0W-20
-
✅ Valvoline Advanced Full Synthetic dexos1 0W-20
Look for the dexos1 Gen3 approval mark on the bottle. dexos1 Gen2 bottles are still in circulation — they are not equivalent to Gen3.
Severe Service Check
Use the 3750-mile interval if you:
- Tow a trailer, boat, or fifth-wheel regularly
- Drive in sustained off-road conditions
- Operate in extreme dust, sand, or gravel environments
- Make frequent short trips under 5 miles in cold weather
- Idle for extended periods (taxis, drive-throughs, remote start in cold climates)
Installation Details
Drain Plug Torque: 18 ft-lbs
OEM Filter: ACDelco PF64 (spin-on)
Aftermarket Filters:
-
Fram PH10575
-
Mobil 1 M1-212A
-
Bosch 3323
Pro Tip: The Yukon XL holds 8.0 quarts — have at least two 5-quart jugs on hand. The drain plug is 15 mm. Use the GM Oil Life Monitor (OLM) to guide change intervals, but never exceed 12 months regardless of percentage remaining.
FAQs
What oil does a 2024 GMC Yukon XL 5.3L take?
0W-20 full synthetic meeting GM dexos1 Gen3 (API SP). dexos1 Gen2 is not the same specification.
How many quarts does the Yukon XL V8 need?
8.0 quarts with a new filter, 7.5 without. This is one of the larger capacities in the GMC lineup.
Can I use 5W-30 if I can’t find 0W-20 dexos?
In an emergency, GM permits 5W-30 dexos1 as a temporary substitute. Change to 0W-20 dexos1 Gen3 at the next opportunity.
How does the Oil Life Monitor (OLM) work?
The OLM calculates oil degradation based on engine revolutions, temperatures, and load cycles — not just mileage. It may recommend changes before 7,500 miles under severe use, or allow longer intervals under gentle highway driving.
Does the Yukon XL use the same oil as the standard Yukon?
Yes — both the Yukon and Yukon XL with the L84 5.3L V8 use the same oil specification and capacity.
How often should I change the oil?
Follow the OLM indicator. The 7500-mile guideline applies to normal mixed driving. Severe towing or off-road use: 3750 miles.
