General Motors is committed to designing, building, and selling cars that perform well and last a long time—and to making the experience of owning a GM vehicle highly rewarding. That's why GM Powertrain engineers developed the dexos® engine oil specification. The result is engine oil designed specifically for your GM engine, with added performance in areas important to its operation. dexos® represents a high quality, robust oil formulated to some of the most rigorous specifications in the industry. And just like GM, dexos® is global. GM wants to make sure that every GM car in the world has access to the highest quality oil formulated exclusively for GM engines.
