What oil brand does GM recommend?
General Motors (GM) recommends using Dexos-certified motor oils in their vehicles. Dexos is GM's proprietary oil specification that ensures the oil meets their strict performance and quality standards.
What is Dexos Certification?
Dexos is GM's own oil specification that goes beyond industry standards to provide enhanced protection for GM engines. Dexos-certified oils are formulated to work optimally with GM's engine designs and technologies. These oils help improve fuel economy, reduce emissions, and provide superior wear protection compared to conventional motor oils.
Recommended Dexos-Certified Oil Brands
GM recommends using one of the following Dexos-certified motor oil brands in their vehicles:
- Mobil 1
- Castrol
- ACDelco
- Valvoline
- Shell Rotella
- Pennzoil
These brands have all been tested and approved by GM to meet the Dexos specification. Using a Dexos-certified oil helps ensure your GM vehicle's engine receives the proper lubrication and protection it needs.
Importance of Using Dexos Oil
Using the recommended Dexos-certified oil is important for maintaining your GM vehicle's warranty coverage. GM requires the use of Dexos oils to uphold the terms of their engine and powertrain warranties. Failure to use the proper oil could potentially void your warranty if engine damage occurs.
In addition to warranty coverage, Dexos oils help maximize the performance and longevity of your GM engine. The specialized formulation provides enhanced protection against wear, deposits, and sludge buildup compared to conventional motor oils. This helps keep your engine running smoothly and efficiently for longer.
What happens if you put non Dexos oil in a Dexos engine?
Similar to full synthetic or synthetic blend motor oils, dexos oil should not be mixed with conventional or non-dexos oils. Incorporating these two types of oils can result in a loss of the properties that give dexos oil its superior performance.

You would want to use an oil with Dexos because the newer engines (especially the DFE ones) requires the additives that Dexos has to allow better flow to the upper cylinders. The ports are small and carbon is a factor in DFI engines. Keeping those ports passage free, the Dexos formula oils helps.
