The Buick Verano typically requires Dexos1 Gen 2 synthetic motor oil, most often in 5W-30 viscosity. Exact requirements can vary by engine variant and climate, so always verify with the owner's manual or the oil cap.
Oil specification and viscosity
Understanding the correct oil specification helps ensure protection, fuel economy, and warranty coverage for the Verano. General GM guidance for newer gasoline engines under the Dexos1 Gen 2 standard is to use oils that meet that specification, with viscosity chosen based on engine and environment.
For the Verano, the two common engines are the 2.4L Ecotec and the 2.0L turbo. In most cases, both engines use Dexos1 Gen 2 oil and typical viscosity is 5W-30, but regional climate and model year can influence the exact requirement. The safest approach is to check the oil fill cap and the owner’s manual for the precise specification and viscosity.
What to keep in mind when shopping for oil:
- Oil type: Dexos1 Gen 2 certified motor oil (synthetic or synthetic-blend is commonly preferred).
- Viscosity: Commonly 5W-30 for many Verano models; some climates or model years may specify 0W-30, 0W-20, or 5W-20—verify the exact number in the manual.
- Form: Full synthetic or synthetic-blend oils are typically recommended; avoid plain conventional oil unless explicitly allowed by GM documentation.
- API rating: Look for a current API rating such as SN or newer (SP) as indicated by GM for your engine.
Following the Dexos1 Gen 2 standard and the correct viscosity helps ensure engine longevity and smooth operation across seasons. Always confirm with the official documentation for your exact vehicle and region.
Engine variants and oil requirements
2.4L Ecotec engine
The 2.4L engine used in base Verano models generally requires Dexos1 Gen 2 oil with a viscosity around 5W-30 in typical climates. Mismatches in viscosity can affect cold-start protection and overall performance, so the manual should be consulted for any climate-specific notes.
2.0L turbo engine
The Verano Turbo’s 2.0L turbocharged engine also relies on Dexos1 Gen 2 oil, commonly 5W-30, though regional variations may apply. Always verify the precise viscosity and specification in the vehicle’s manual or on the oil fill cap.
Maintenance tips and oil changes
Maintenance intervals and capacity can vary by year and driving conditions. In general, Dexos1 Gen 2 synthetic oil is designed to support longer change intervals under normal use, with more frequent changes recommended in severe service (extreme temperatures, frequent short trips, towing, or heavy city driving). The oil capacity is roughly in the 4-5 quart range, depending on engine variant and whether you’re replacing the oil filter.
- Consult the owner’s manual or dealer for the exact oil specification and change interval for your Verano’s engine.
- Use a Dexos1 Gen 2 certified oil at the recommended viscosity (commonly 5W-30, but verify for your model/year).
- Replace the oil filter with every oil change and use a compatible OEM or reputable aftermarket filter.
- Ensure proper oil fill to the OEM specified level after changing oil; run the engine briefly and recheck the dipstick.
Following these steps helps maintain engine protection and performance while honoring GM’s recommended specifications.
Where to find the exact specification
To be sure you’re using the correct oil for your Buick Verano, check the following sources: the vehicle’s owner’s manual, the oil cap under the hood, and the vehicle’s maintenance schedule provided by GM. If in doubt, ask a Buick dealer or a certified mechanic to confirm Dexos1 Gen 2 compatibility and the precise viscosity for your engine and climate.
Summary
In short, the Buick Verano generally takes Dexos1 Gen 2 motor oil, with 5W-30 being the most common viscosity for many engines, though regional and model-year variations can apply. Verify exact specifications on the oil cap or in the owner’s manual, use Dexos1 Gen 2 certified oil, and follow the recommended change intervals to keep the Verano running smoothly across seasons.
Is 5W-20 or 5W-30 better for older cars?
Key Differences: 5W30 vs 5W20
5W30 offers better high-temperature protection. It's great for towing, highway driving, or older engines, especially for drivers in Frandor and Lansing who use their vehicles for more than just errands. 5W20 is thinner and generally suited for newer engines that prioritize efficiency.

What type of oil does a 2016 Buick Verano use?
Oil Grade: SEOC3
| Viscosity: | 0W-30 (Below -29°C) 5W-30 (All TEMPS) |
|---|---|
| Torque: | 18 ft/lbs (Oil Drain Plug) |
| Notes: | (1) If using E85 or M85 fuels, use AMSOIL of the appropriate viscosity for the OEM recommended drain interval. Extended oil drains can only be extended through oil analysis when these fuels are used. |
Does Buick need synthetic oil?
Choosing the right oil: Always use Buick-approved oil that meets the dexos1 specification and the proper SAE viscosity grade, such as ACDelco dexos1® Full Synthetic. You can find the specific requirements for your SUV in your Owner's Manual or by consulting your dealer.
