The 2014 Buick Verano requires Dexos1 Gen 2 5W-30 full-synthetic motor oil.
In more detail, the Verano’s two gasoline engines—the 2.4L inline-4 and the available 2.0L turbo—call for oil that meets GM’s Dexos1 Gen 2 specification with a viscosity of 5W-30. Using oil outside this specification can affect lubrication, emissions, and warranty coverage. The guidance below explains what to buy, how much to use, and how often to change it, so you can keep the engine running smoothly.
Recommended oil specification
What to look for when shopping for oil and filters for the 2014 Verano:
- Dexos1 Gen 2 certified 5W-30 full-synthetic motor oil. This is the standard specification for GM gasoline engines of this era.
- Use a GM-approved oil filter (AC Delco or equivalent) that matches the Dexos1 Gen 2 specification.
- Avoid oils not rated Dexos1 Gen 2, as compatibility and warranty protection may be compromised.
Using the correct oil and filter helps ensure proper lubrication, engine cleanliness, and warranty compliance for both the 2.4L and 2.0L turbo versions.
Capacity and service intervals
Practical guidelines for maintaining the oil in a 2014 Verano:
- Oil capacity (with filter): approximately 5 quarts (about 4.7 liters).
- Recommended oil change interval: typically every 7,500 to 10,000 miles under normal driving conditions when using Dexos1 Gen 2 5W-30 full synthetic oil. In severe driving conditions (short trips, heavy traffic, extreme temperatures, frequent towing), more frequent changes are advised, potentially 3,000–5,000 miles.
Always verify the exact capacity and interval in your owner’s manual or with a Buick service adviser, as engine variant and regional recommendations can affect the numbers. After servicing, reset the vehicle maintenance minder if applicable and confirm the oil level with the dipstick.
Additional tips for buyers and owners
To avoid mix-ups, keep a small checklist handy:
- Buy only Dexos1 Gen 2 5W-30, not generic or non-Dexos oils.
- Confirm the oil filter is compatible with Dexos1 Gen 2 and your engine type.
- If you’re unsure which engine your Verano has, consult the owner’s manual or a dealer to confirm the correct oil specification for your VIN.
Following these guidelines helps ensure optimal performance, fuel efficiency, and long-term reliability for the 2014 Buick Verano.
Summary
In brief, the 2014 Buick Verano needs Dexos1 Gen 2 5W-30 full-synthetic oil, with an approximate capacity of 5 quarts and typical change intervals of 7,500–10,000 miles under normal conditions. Use Dexos1 Gen 2 certified oil and a matching filter, and refer to the owner's manual or dealer for your specific engine variant and local driving conditions. Proper maintenance supports performance and warranty protections for the vehicle.
