Dexos is a specification for motor oil created by General Motors. It replaces the GM-LL-A-025 and GM6094M specifications.
Dexos is a performance specification for motor oil developed by General Motors. It is designed to deliver improved fuel economy and protection for engines that operate on gasoline containing up to 10% ethanol. The specification requires the use of low-viscosity oils that meet certain standards for wear protection, deposit control, and piston cleanliness.
Do I Need to Use Dexos Oil?
Yes, you need to use Dexos oil in your car. Here’s why: Dexos oil is a special type of motor oil that is designed specifically for use in General Motors vehicles.
It provides superior protection for engines compared to conventional motor oils, and it is the only motor oil approved by GM for use in its vehicles. Using Dexos oil can help improve your fuel economy and extend the life of your engine. It also helps reduce emissions and protect against wear and tear.
Overall, using Dexos oil is the best way to keep your GM vehicle running smoothly and efficiently.
Is Dexos Oil the Same As Synthetic Oil?
No, Dexos oil is not the same as synthetic oil. Dexos is a specification for motor oils developed by General Motors. It covers a range of requirements including fuel economy and emission system protection.
Synthetic oils are man-made oils that can be tailored to meet specific needs, such as high-temperature performance or low-friction properties.
Does Dexos Make a Difference?
The short answer is yes, Dexos does make a difference. Here’s a closer look at why this motor oil specification matters and how it can benefit your car. Created by General Motors (GM), Dexos is a motor oil specification that was designed to meet the needs of GM vehicles.
While other motor oils may work in GM cars, using an oil that meets the Dexos specification can offer several advantages. One key benefit is that Dexos-approved oils are designed to help improve fuel economy. GM estimates that using Dexos motor oil in its vehicles can lead to a 1.5% improvement in fuel economy compared to using conventional motor oil.
That may not sound like much, but it can add up over time – especially if you do a lot of driving. In addition to better fuel economy, using Dexos motor oil can also help improve engine performance and extend engine life. That’s because these oils are formulated with high-quality base stocks and additives that protect against wear, deposits, and corrosion better than conventional oils.
As a result, engines that use Dexos oil tend to run smoother and last longer than those that don’t. So, if you own a GM vehicle (or any vehicle that recommends the use of de Xos motor oil), it’s worth making the switch to this higher-quality option. You may not notice an immediate difference, but over time you’ll likely see improved fuel economy and engine performance – which could end up saving you money in the long run.

The main criteria include: improved fuel economy performance, deposit control, wear protection, piston cleanliness, low volatility, and emission system compatibility. In addition, the oil must also maintain its viscosity over a wide range of temperatures (-37°C to 107°C), have good high temperature/high shear stability, and a low NOACK volatility.
Can You Use Dexos Oil in Any Car
Not all oils are created equal. Just because a product has the same API service rating as another oil, does not mean they can be used interchangeably. Most motor oils are not compatible with one another.
So, what happens if you use the wrong oil in your car? The American Petroleum Institute (API) is responsible for creating and maintaining the standards for motor oil quality in the United States. The API issues two different types of ratings for motor oils—service classifications and performance levels.
Service classifications indicate whether an oil meets the minimum requirements established by vehicle manufacturers to protect against engine wear, while performance levels show how well an oil performs compared to other oils with the same service classification. To ensure that your car’s engine is properly lubricated and protected from wear, it is important to use an oil that meets the specific requirements outlined by your vehicle’s manufacturer. Many automakers have their unique specifications for motor oil—known as dexos1—that must be met for warranty coverage to remain intact.
While there are many different brands of motor oil on the market that claim to meet dexos1 specifications, not all of them are created equal. To ensure that you are using high-quality dexos1-approved motor oil in your car, look for products that carry the GM Certified mark of approval.
Conclusion
Dexos is a specification for motor oil developed by General Motors. It was introduced in 2012 as a response to the many different types of oil being used in GM vehicles. Dexos is designed to provide better fuel economy and protection against engine wear.
It is also compatible with GM’s start-stop technology, which shuts off the engine when the vehicle is not in use.
