Complete Oil Specifications
Your 2023 Buick Envision with the 2.0T LSY engine requires 0W-20 full synthetic oil meeting GM dexos1 Gen3 and API SP / ILSAC GF-6A. The LSY turbocharged four-cylinder is GM’s workhorse compact engine, providing a balance of performance and efficiency in the Envision’s premium compact crossover package.

Why dexos1 Gen3 for the LSY Turbo
The LSY uses Gasoline Direct Injection (GDI) and an automatic stop/start system that cycles the engine repeatedly in urban driving — each restart is a cold start for the turbo bearings. dexos1 Gen3 is specifically formulated to resist the fuel dilution that GDI engines are prone to, and provides enhanced Low-Speed Pre-Ignition (LSPI) protection. The stop/start cycling also makes oxidation stability critical — Gen3 oils maintain their protective properties through far more thermal cycles than conventional oils.
Using incorrect oil will:
- ❌ Increase LSPI risk from fuel dilution in the GDI combustion chamber
- ❌ Accelerate oil oxidation from stop/start cycling
- ❌ Void the Buick powertrain warranty (dexos1 approval required)
Buick-Approved Oil Brands
-
✅ ACDelco dexos1 Gen3 Full Synthetic 0W-20
-
✅ Mobil 1 dexos1 Gen3 Full Synthetic 0W-20
-
✅ Pennzoil Platinum dexos1 Gen3 Full Synthetic 0W-20
-
✅ Castrol Edge dexos1 Gen3 Full Synthetic 0W-20
-
✅ Valvoline Modern Engine Full Synthetic dexos1 0W-20
Look for the dexos1 Gen3 approval mark on the label. dexos1 Gen2 oils do not meet the 2023 Envision’s specification.
Severe Service Check
Use the 3750-mile interval if you:
- Drive primarily in urban stop-and-go traffic (exacerbates fuel dilution and stop/start cycling)
- Make frequent short trips under 5 miles
- Tow or carry heavy loads regularly
- Operate in extreme cold below 0°F

Pro Tip: The GM Oil Life System in the Envision calculates change intervals based on engine revolutions, temperature cycles, and load — it is more accurate than a fixed mileage schedule. Trust the indicator, but treat 7,500 miles as the maximum regardless of what it shows.
FAQs
What oil does a 2023 Buick Envision take?
0W-20 full synthetic with GM dexos1 Gen3 approval.
How many quarts does the Envision 2.0T need?
5.3 quarts with a new filter, 5.0 without.
What’s the difference between dexos1 Gen2 and Gen3?
Gen3 adds enhanced LSPI protection and improved fuel dilution resistance — both critical for the LSY’s direct injection and stop/start system. Use Gen3 in the 2023 Envision.
Is synthetic oil required?
Yes. dexos1 Gen3 requires full synthetic formulation.
How often should I change the oil?
Every 7500 miles maximum. The GM Oil Life System may prompt earlier based on your driving conditions.
