The Buick Verano generally uses Dexos1 Gen 2 compliant motor oil with a viscosity of 5W-30. In most US-market Verano models, the 2.4-liter Ecotec engine calls for Dexos1 Gen 2 5W-30, usable in synthetic or synthetic-blend forms, with an oil capacity of about 5 quarts (4.7 liters) and typical change intervals around 7,500 miles under normal driving.
The following article explains the oil specification in more detail, how it applies across common Verano configurations, and how to maintain the engine with the correct oil. Always confirm the exact requirement for your year and engine from the owner's manual or a Buick dealer.
Oil type and specification
The key details you should know about the oil for Buick Verano include viscosity, certification, capacity, and maintenance timing.
- Viscosity and certification: 5W-30 Dexos1 Gen 2 certified motor oil to ensure compatibility with GM engines and emissions systems.

Additional guidance by engine variant and market
Turbo and other variants
Some Verano configurations offered in certain markets may include a turbocharged engine. In general, these variants still rely on Dexos1 Gen 2 5W-30 oil, though performance and climate conditions can influence suggested change intervals. Always confirm with the exact vehicle documentation for your year and engine.
