Complete Oil Specifications
Your 2021 Cadillac Escalade 6.2L V8 requires 0W-20 full synthetic engine oil meeting the GM dexos1 Gen 2 specification.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 0W-20 |
| API Rating | API SP, SN Plus |
| ILSAC Rating | GF-6A |
| Capacity (with filter) | 8.0 quarts |
| Oil Filter | ACDelco PF63E |
| Normal Interval | 7500 miles |
Why 0W-20 is Critical for This Engine
The massive 6.2L V8 features Dynamic Fuel Management technologies to maximize efficiency. The lightweight 0W-20 viscosity allows the oil to immediately flow and actuate the precise hydraulic lifter mechanisms needed for seamless cylinder deactivation.
Using incorrect oil will:
- ❌ Prevent proper cylinder deactivation (leading to CELs)
- ❌ Negatively impact engine fuel economy by adding parasitic drag
- ❌ Provide insufficient cold-start protection to overhead cam components
Cadillac-Approved Oil Brands
-
✅ ACDelco dexos1 Gen 2 Full Synthetic 0W-20
-
✅ Mobil 1 Advanced Fuel Economy 0W-20
-
✅ Valvoline Advanced Full Synthetic 0W-20
-
✅ Pennzoil Platinum Full Synthetic 0W-20
-
✅ Castrol EDGE 0W-20 Advanced Full Synthetic
Only use oils marked distinctly with the dexos1 Gen 2 (or backward compatible Gen 3) logo. Non-dexos oils may lack the low-temperature pumpability and high-temperature oxidation resistance mandated by General Motors for their V8 engines.
Severe Service Check
You need the 5000-mile interval if you:
- Tow heavy loads, trailers, or boats
- Drive primarily in stop-and-go city traffic
- Let the Escalade idle extensively
- Live in areas with significantly dusty environments or extreme temperatures

Pro Tip: Verify that the rubber gasket from the old oil filter hasn’t stuck to the engine block mounting surface. A “double gasket” scenario will cause an immediate and massive oil leak when the engine starts.
FAQs
What oil does a 2021 Cadillac Escalade 6.2L V8 take?
0W-20 full synthetic oil meeting dexos1 Gen 2 standards.
How many quarts does it need?
8.0 quarts with a new filter.
Can I use a different viscosity?
GM mandates 0W-20 for the 2021 6.2L V8 under almost all normal operating conditions. (Note: A later GM update for certain build dates permitted 0W-40 Dexos R, consult your specific oil filler cap).
Is synthetic oil required?
Yes, dexos1 Gen 2 oils are fully synthetic to meet the strict thermal breakdown protective standards of modern GM V8s.
How often should I change the oil?
When indicated by the Oil Life Monitoring System, or roughly every 7500 miles (or 5000 miles for severe service). Do not exceed 1 year.
