Dexos is a motor oil specification developed by General Motors (GM) for use in their vehicles. It is a performance-based standard that specifies the quality and performance requirements for engine oils used in GM vehicles.
Dexos motor oil is designed to provide enhanced protection for engine components, improve fuel efficiency, and reduce emissions. It also meets the latest industry standards for low-emission vehicles and provides protection for engines with extended drain intervals.
The Dexos specification covers several different viscosity grades, including SAE 5W-30, SAE 10W-30, and SAE 5W-20. To be certified as Dexos-compliant, motor oil must meet rigorous standards for wear protection, deposit control, and performance in high-temperature conditions.
If you own a GM vehicle, it is recommended to use Dexos-compliant oil to ensure optimal performance and protection for your engine. However, Dexos motor oil can also be used in other vehicles that specify the use of a particular viscosity grade and performance level.
