dexos® Licensing Program
GM Global Propulsion
Systems engineers developed the dexos® engine oil specification to meet the increasing demands of today’s engines. Fuel economy improvements combined with the need for engine oil robustness is driving change at an increased pace. Fuel economy improvement can be met through a variety of ways, such as reduced friction, optimized viscometrics, and aeration control which enable the engine to operate more efficiently. The result is engine oil designed specifically for GM’s engines, 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 vehicle anywhere in the world has access to the highest quality oil formulated specifically for GM engines.
dexos® licensed products are easy to identify. Simply look for the dexos® icon on the front label and the 11 digit alphanumeric dexos® license number on the back label. As long as an oil package displays these two markings, the engine oil is an authentic, licensed dexos® product and is recommended for use in GM vehicles.
If you are an oil manufacturer or marketer who wants to become licensed to blend or sell authentic dexos® oil, please see the Licensing Program page to begin the licensing process.
