General Motors list of Licensed dexos® brands is updated quarterly, with the most recent update on December 16, 2020.
General Motors recommends the use of dexos™ approved engine oils for global factory and service fill in spark ignited and diesel engines. Importantly, the number of brands with dexos approved licenses varies over time. The list of Licensed dexos® brands is updated quarterly, with the most recent update on December 16, 2020.
dexos®1 Gen 2 licensed motor oils are recommended for use in gasoline-fueled GM vehicles. 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. Unless an oil package displays these two markings, the motor oil is not an authentic licensed dexos product and is not recommended for use in GM vehicles.
Refer to the owner’s manual for proper engine oil requirements.
dexos1 Gen 2 was introduced in 2015 as an upgrade to dexos1. Gen 2 provides the benefits of the first dexos generation plus protection against low speed pre-ignition (LSPI) and improved oxidation and deposit control. As of August 31, 2017 all licenses for General Motors first-generation Dexos1™ passenger car engine oils expired – those products may no longer be manufactured or sold.
