What is Dexos 1?

Dexos 1 was introduced in 2004 as a fuel system lubricant designed for diesel engines. Car manufacturers required it to be used in their vehicles built from the model year 2004 and beyond. In order for a car manufacturer to use the Dexos logo on their engine, the additive had to pass American Petroleum Institute (API) specification CK-4.

Dexos 1 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 1 is not designed for gasoline engines and should not be used in them.

What is Dexos 2?

In order for a car manufacturer to use the Dexos logo on their engine, the additive has to pass American Petroleum Institute (API) specification CJ-4. In 2016, this specification was revised and codified as CJ-4+. Because of this, “Dexos 2” is not a new version of Dexos 1 but a new product that meets the revised API specification.

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.

Main Difference

As We Seen While Reviewing Dexos 1 and Dexos 2 are both high quality fuel system lubricants that protect engines from damage caused by sulfur in the fuel. However, there are some key differences between these two products:

1) The API Specification:

• Dexos 1 was introduced in 2004 as a fuel system lubricant designed for diesel engines that meet API specification CK-4.
• Dexos 2 was introduced in 2016 as a fuel system lubricant designed for gasoline and diesel engines that meet API specification CJ-4+.

3) The Intended Market:

• Dexos 1 was originally developed for use in cars manufactured by General Motors.
• Dexos 2 is not limited to use only in General Motors vehicles, but can be used in any gasoline or diesel engine.

4) The Quality And Performance:

Our Overall Opinion, Both Dexos 1 and Dexos 2 are high quality products that help to protect engines from damage caused by sulfur in the fuel. However, Dexos 2 has been specifically designed to meet the revised API specification CJ-4+, which makes it even more compatible with gasoline engines and provides even better performance.

Does Dexos 1 and 2 Mean the Same Thing?

No. Although they are both fuel system lubricants, Dexos 1 and Dexos 2 mean two different things. Because the API specification was revised in 2016, there is no longer any difference between “Dexos 1” & “Dexos 2.” They are simply two names for the same product.

Which Product Should I Use?

The best way to decide which product to use is to consult your car’s owner’s manual. If it doesn’t mention Dexos 1 or 2, you can assume that your vehicle does not require either. However, if it says one or both of these products, be sure to use the recommended one for your vehicle.

What Happens If I Don’t Use Dexos Oil?

As per users and experts, there are no problems like engine detriment or less mileage as long as the fuels are entirely synthetic. The manufacturer although, claims an increase in vehicle performance using the stated oil. We would recommend taking no chance while you are protected under the warranty as the service center can ask you to show receipt of the oil used. Failing to show specifics can shorten your claim on the warranty.

What Brands Of Oil Are Dexos?

Most of the categories’ oils have a viscosity of 0w20, 5w20, or 5w30. The quality of the synthetic stocks used is the best in the business. Many companies now produce oil by meeting the requirements and industry-set standards. The list is huge. Some of the big names who excel in making the product are Vesco, GM, Amalie, Shell, Castrol, Valvoline, ExxonMobil, and many more.

How Much Is A Dexos Oil Change?

The oil change for the following product will cost you an additional of 30 percent. In terms of numbers, say that you have to pay 5 dollars extra for every oil change. But implementing this oil, your car will perform better in every sphere and you will be good for like 10,000 miles where the conventional oil needs to be changed after every 3,000 miles with no significant benefits in the performance.

In conclusion, Dexos 1 and Dexos 2 are both high-quality fuel system lubricants that help protect diesel and gasoline engines from damage caused by sulfur in the fuel. However, they are not interchangeable and should only be used as recommended by your car’s owner’s manual. Thanks for reading!
