What brand of oil does Chevy use?

Chevrolet, a division of General Motors, recommends using Dexos1 or Dexos2 engine oil in most of its vehicles. Dexos is a proprietary oil specification developed by GM to meet the lubrication requirements of its modern engines.


Dexos Engine Oil Specifications


Dexos1 and Dexos2 are GM's two main engine oil specifications. Dexos1 is designed for gasoline engines, while Dexos2 is for diesel engines. Both specifications are intended to provide improved fuel economy, reduced emissions, and enhanced engine protection compared to conventional motor oils.



  • Dexos1 is the recommended oil for most Chevrolet gasoline-powered vehicles, including cars, SUVs, and light-duty trucks.

  • Dexos2 is the recommended oil for Chevrolet diesel-powered vehicles, such as the Silverado HD and Tahoe Diesel.


Chevrolet owners should always refer to their owner's manual to determine the specific oil type and viscosity recommended for their vehicle.


Why Dexos Oil?


Chevrolet uses the Dexos specification to ensure its engines receive the proper lubrication and protection. Dexos oils are formulated to meet stringent performance and quality standards set by GM. Using the recommended Dexos oil can help maintain the warranty coverage and optimal performance of Chevrolet vehicles.



  • Dexos oils are designed to provide better wear protection, improved fuel economy, and reduced emissions compared to conventional motor oils.

  • The Dexos specification also helps ensure compatibility with Chevrolet's engine components and emission control systems.

  • GM regularly tests and approves Dexos-licensed oils from various manufacturers to ensure they meet the required standards.


In summary, Chevrolet recommends using Dexos1 or Dexos2 engine oils in its vehicles to ensure optimal performance, protection, and warranty coverage.
