You can only use full synthetic oil instead of dexos oil if it meets the GM Dexos Standard. So, in a way, the answer is in checking the required standards.
The plus point is, that most synthetics are Dexos nowadays. Even some non-synthetics are dexos certified. Back in the day, using them would have violated your warranty. Now, you have more options.
Still, you may have some questions that need answering. We are here to answer in detail. So, why wait? let’s jump right in.

Full Synthetic vs Dexos Oil: The Key Difference
Dexos is also a type of synthetic oil, as you know. What makes them different from full synthetic is the GM Dexos standard. But to give you a clear idea, we have a table indicating the key differences here:
| Characteristic | Full Synthetic Oil | Dexos Oil |
|---|---|---|
| Base Oil | Pure synthetic compounds | Can be synthetic or mineral |
| Performance Benefits | – Excellent high-temperature stability\n- Reduced friction\n- Better fuel efficiency\n- Superior wear protection | – Designed for modern gasoline engines\n- Provides good engine protection\n- Enhances fuel economy |
| Viscosity Grades | Available in various viscosities (e.g., 0W-20, 5W-30, 10W-40) | Typically available in recommended grades (e.g., 5W-30, 5W-20) |
| Engine Compatibility | Suitable for a wide range of vehicles, including high-performance and turbocharged engines | Designed for specific engine types, especially in GM vehicles |
| Additive Package | Contains advanced additives for improved performance and engine protection | Formulated to meet GM’s performance requirements and specifications |
| Price | Generally more expensive than conventional or synthetic-blend oils | May vary but often competitively priced with other synthetic oils |
| Change Interval | Typically recommended for longer oil change intervals (e.g., 7,500 to 10,000 miles) | Follow manufacturer recommendations for oil change intervals |
| Recommended Use | Ideal for high-performance, luxury, and vehicles with extended oil change intervals | Recommended for GM vehicles, particularly for warranty maintenance |
| API Certification | Meets or exceeds API (American Petroleum Institute) standards | Meets GM’s Dexos specifications, which include API standards |
What Is GM Approved Dexos Oil and Why Use It?
Dexos engine oil specification is a tailor-made solution exclusively for GM engines. It’s not just any oil; it’s a strategic choice to enhance vehicle performance and longevity. Dexos is engineered with a multi-fold purpose: boosting fuel efficiency, extending the life of emissions systems, reducing the frequency of oil changes, and ultimately extending the life of your vehicle.
Starting in 2011, all new GM vehicles come equipped with Dexos oil as standard, and here’s why it’s a game-changer.
Firstly, Dexos is meticulously designed to optimize fuel efficiency. It’s not just about saving money at the pump; it’s also about reducing your carbon footprint.
Secondly, Dexos helps your emissions system go the extra mile. This means fewer pollutants released into the environment and a cleaner, greener ride.
Thirdly, Dexos reduces the hassle of oil changes. With longer intervals between changes, you save both time and money while keeping your engine well-lubricated.
Moreover, if you own an older GM model, you can still benefit from Dexos. It’s compatible with a wide range of GM vehicles, ensuring they run smoothly and efficiently.
Can You Use Non Full Synthetic Dexos Oil?
So far, you can. But we recommend you avoid that.
Most people prefer to create blends so that they can save up a few bucks. Even though using Non-full synthetic Dexos oil is not bad, it’s not proven healthy for the engine either.

Full Synthetic Dexos or Blend Dexos Oil: Which One is Better?
Full synthetic Dexos oil is the recommended choice because it offers superior performance and engine protection compared to blended Dexos oil.
Full synthetic oil is made entirely from synthetic base oils and advanced additives, providing excellent high-temperature stability, reduced friction, better fuel efficiency, and superior wear protection. These qualities are especially beneficial for modern engines, as they ensure optimal lubrication and protection under various operating conditions.
On the other hand, blend Dexos oil is a mixture of synthetic and conventional base oils, which may compromise some of the performance benefits of full synthetic oil. While it can still meet the minimum Dexos specifications, it may not provide the same level of protection and longevity for your engine.
Wrapping Up
As you can see, you better check for GM Dexos standards before using any full synthetic oil. Doing so, you can keep your warranty.
