Complete Oil Specifications
Your 2023 Chevrolet Traverse 3.6L V6 requires 5W-30 full synthetic oil meeting API SP and GM’s dexos1 Gen 2 standards.
Quick Reference
| Specification | Value |
|---|---|
| Viscosity | 5W-30 |
| API Rating | API SP / dexos1 Gen 2 |
| ILSAC Rating | GF-6A |
| Capacity (with filter) | 6.0 quarts |
| Oil Filter | ACDelco PF63E |
| Normal Interval | 7500 miles |
Why 5W-30 is Critical for This Engine
The 3.6L V6 engine utilizes hydraulic timing chain tensioners and variable valve timing (VVT) solenoids. GM specifically engineered these tight tolerances around the flow characteristics of 5W-30 oil to provide immediate pressure during cold starts and proper shear stability when hot. Note that while Gen 3 oils exist, Gen 2 is the official minimum specification required for this engine year.
Using incorrect oil will:
- ❌ Prevent proper operation of the VVT phasers, triggering a Check Engine Light.
- ❌ Accelerate wear on hydraulic timing chain tensioners leading to costly chain rattling.
- ❌ Compromise the strict dexos1 deposit-control requirements, causing sludge buildup in oil galleys.
Chevrolet-Approved Oil Brands
-
✅ ACDelco dexos1 Gen 2 Full Synthetic 5W-30
-
✅ Mobil 1 Advanced Full Synthetic 5W-30
-
✅ Castrol Edge Full Synthetic 5W-30

Always look for the green dexos1 Gen 2 (or Gen 3) logo on the bottle to ensure you are protecting your factory warranty.
Severe Service Check
You need the 5000-mile interval if you:
- Drive mostly short trips (under 5 miles)
- Frequently idle in stop-and-go city traffic
- Experience extreme temperatures (consistently over 90°F or below 10°F)
- Tow a trailer, camper, or haul heavy cargo
- Drive in dusty or coastal conditions
Installation Details
Drain Plug Torque: 18 ft-lbs
Warning: Over-tightening the drain plug can easily strip the aluminum oil pan threads.

Pro Tip: Always double-check that the old oil filter gasket ring came off with the old filter. If it sticks to the engine block housing and you screw the new filter on top of it, the system will blow out the oil upon starting the engine.
FAQs
What oil does a 2023 Chevrolet Traverse 3.6L V6 take?
5W-30 full synthetic oil meeting the API SP and dexos1 Gen 2 / Gen 3 specification.
How many quarts does it need?
6.0 quarts with a new filter.
Can I use 5W-20 instead?
No. Using thinner oil than recommended will reduce oil pressure in the VVT system and fail to properly lubricate the timing chains under load.
Is synthetic oil required?
Yes. Only full synthetic oil can meet the stringent deposit and oxidation standards of the dexos1 specification required to maintain your warranty.
How often should I change the oil?
Every 7500 miles for normal driving, or every 5000 miles for severe service. Do not exceed the threshold determined by the Traverse’s intelligent Oil Life Monitor (OLM).
What does dexos1 mean?
dexos1 is General Motors’ proprietary oil specification that often exceeds the standards required by ILSAC and API. It’s designed specifically for GM engines to prevent aeration, block low-speed pre-ignition (LSPI), and reduce turbo/engine deposits.
