Dexos 2 is primarily for diesel engines; however, you can still use it in gas engines, and there won’t be any immediate consequences. That said, some damage is possible, given enough time. That said, Dexos 2 is approved for use in smaller European market GM engines. What Will Happen If I Don’t Use Dexos Oil? In terms of suitable models, they are both equal. But that wasn’t always the case. Dexos 1 gen 1 used to license synthetic blended oils.

That said, the Dexos 2 oil isn’t as versatile as Dexos 1. While you can use a Dexos 1 with all gasoline engines as long as it’s the right viscosity, that’s not the case with Dexos 2 and diesel engines. But it will not be possible to get the whole oil out of your engine and change it twice. Though you will 99% change the rest of the stability will put no harmful effect on your engine. Dexos full synthetic motor oils To compare the worth of dexos 1 oil with that of dexos 2, you should know that both have their own strengths. Still, if we look at their overall performance, dexos 1 certainly overpowers dexos 2. Dexos 1 Generation 2 and Generation 3 were the results of a blunder made by dexos 1 Generation 1.

Dexos 2 is a diesel engine that uses fuel fromloppered tanks to the vehicle’s system. Suitable engines for Gasoline engines? Yes, there are two Dexos 1 can run on gasoline while Dexter 2 can run on Diesel. Design Dexos 2 is a high-quality fuel system lubricant that helps to protect diesel engines from damage caused by sulfur in the fuel. It also helps to clean the engine and keep it running smoothly. Dexos 2 is designed for gasoline engines as well as diesel engines. Therefore, supplying dexos 1 for a smaller percentage of gasoline vehicles in Europe would have complicated the supply chain of GM. So, for the convenience of their customers, GM decided to let gasoline engines in Europe also use dexos 2 oils. Given that Dexos oil was introduced in 2011, cars and engines have seen multiple generations since then. And as engines evolve and get new technologies, the motor oil requirements will become more rigorous. That’s why you can find different generations of both Dexos oils.

Castrol EDGE 5W-30 C3 gives you the confidence to demand maximum engine performance from today’s modern, higher revving sports, performance and luxury vehicles requiring a high level of protection and higher performance low viscosity oils. Castrol EDGE 5W-30 C3: The Dexos 1 motor oils and all other motor oils with a Dexos 1 label have to go through a series of different tests that are typically not required by the industry.

Still, they can offer approximately 10,000 miles between oil change durations.

Dexos gives an official license to Mobil 1, including 5W-30, making it the world’s leading synthetic motor oil. Therefore, we can say that Mobil 1 5W30 is dexos approved.

Can You Mix Dexos With Regular Oil? Dexos 1 and 2 are both suitable for models after 2011 but they can also be okay with previous models too. Dexos 1 is suitable for model manufacturers after 2011. Dexos 2 is also suitable for models after 2011 but it can be okay with previous models as well. Dexos 1 vs. Dexos 2: Similarities Fuel Economy Before thinking of an acquisition, it is vital to know, can you use dexos oil in any car or not. In short, the answer is yes. Multiple oils can meet dexos specifications but follow specific instructions. Because GM vehicles come with an oil-life monitor that calculates oil-change intervals based on the number of cold starts, how the engine is driven and other factors, the automaker does not recommend oil changes based on the number of miles alone.
