In this article, we'll explore the GM-approved oils and why they are the recommended choice for your GM vehicle.
GM-Approved Oil Specifications

- dexos2™: This specification is for diesel-powered vehicles and is formulated to provide superior engine protection, improved fuel economy, and reduced emissions.
It's important to note that using a GM-approved oil that meets the appropriate dexos specification is essential for maintaining your vehicle's warranty and ensuring optimal performance.
