What is the Dexos 1 engine oil exactly?

If we understand the exact meaning or functionality of Dexos 1, it basically serves as the lubricant of the fuel system for those engines general motors which run on diesel. In the year 2004, Dexos 1 came into the market. 

Therefore, in the same year (2004) it came into use by the car manufacturer. So, all car models of 2004 which runs on diesel have this lubricant in their vehicle. 

However, there are certain criteria, a car manufacturer has to go through to implement the use of the Dexos logo on their engines general motors. The Additive must pass the API or American Petroleum Institute specification CK-4

Dexos 1 is classified as a fuel system lubricant(oils) in vehicles that have high quality and is capable of protecting the diesel engines conventional oil from the damage of Sulfur that is present in the fuel by specifically designed sludge reduction.

Apart from that Dexos also perform the engine cleaning function and ensure it’s smooth running. 

One major drawback with Dexos1 gen 2 is that it is incompatible with gm the vehicle engines that are run on Gasoline. So, better not to try it(engine oil) on your gasoline engines vehicle.

What is Dexos 2 Exactly?

Same as Dexos 1, the Dexos logo can be used by car manufacturers on their engines only if they pass the American Petroleum Institute specification commonly known as API CJ-4. 

Currently, the specification came to be popular by CK-4+ after the 2016th specification revision. 

Therefore, this makes Dexos 2 a brand new product and not the upgraded version of Dexos 1 . It is actually a new branded product that meets every requirement of 2016 API specifications.

Besides these, the Dexos 2 is also concluded as the high-quality lubricant of the fuel system that is capable of protecting the engine wear on diesel against the sulfur particles which are usually present in the fuel to improve fuel economy.

Additionally, it also mains the smooth operation of the engines and maintains their cleanliness. Apart from diesel engines, Dexos 2 are also designed for gasoline engines as well.

Dexos 1 vs Dexos 2: The ultimate difference & dexos oil specifications

Dexos 1 and Dexos 2 both perform the same function of protecting the gm engines as vehicle meet from the fuel present sulfur particles(api sn) and maintaining their cleanliness and is regarded as the topmost quality lubricant (specially designed with stringent specifications in this new generation of these two oils)of the fuel system.

But there still lies some difference, that is listed below,

  • The specification of API 

  1. Dexos 1 arrived in the market in the year 2004 that performs the fuel system lubrication for engines that are run by diesel only. It follows the API specification CK-4 without more harm.

  2. Whereas, Dexos 2 arrived in the year 2016 that performs the same fuel system lubrication function but for both diesel engines and gasoline engines under the API specification CJ-4+

  • Market intent behind manufacturing these two lubricants dexos oil

  1. Dexos 1 was manufactured with the intention to serve the General motors car units.

  2. But Dexos 2, doesn’t have any limitation towards General Motors only, instead, it can be used by any engines which are being run on either gasoline engines or diesel.

  • Dexos oil Lubricants quality and performance

  1. In the case of quality, both Dexos 2 and Dexos 1 provided their best without any compromise.

  2. In case of performance, also, they give their best in protecting such engines from harmful engine damages caused by the presence of sulfur in fuels of conventional oils.

  3. But the revised API specification CJ-4+ is met by Dexos 2 only, which implies it to be better compatible for specific engines running on gasoline and diesel and regarded to provide enhanced performance if compared with Dexos 1 improved fuel economy.

Common Question

These questions are very common regarding Dexos 1 vs Dexos 2 and should be cleared with in-depth details.

Does Dexos 1 and 2 mean the same product?

Both Dexos1 gen 2 and Dexos 2 perform the same functions and are treated as high-quality fuel system lubricants but still, they aren’t the same. They are two different products with the same name.

Due to the year 2016’s API specification revision, there came a difference as Dexos 2 is a more advanced lubricant intended to serve both diesel and gasoline engines but Dexos 1 is still worthy to serve diesel engines only.

But if the manual points towards one or both the products, you should go the recommended one to be on the safer side.

You won’t be facing any issue as per my personal experience and other car experts’ advice as long as you intend to mass usage of completely synthetic amalie oil fuel synthetic blend. You will be lucky not to witness any kind of minimized more mileage or engine detriment thereafter.

However, the vehicles manufactured recommended engine oil that does tend to enhance the vehicle’s overall performance as claimed by them through synthetic blend. But I would suggest you take no chance at all till your car is totally covered under the warranty as you might need to showcase the engine oil receipt during claiming the service warranty of your car and engine. 

Eventually, gm if you are unable to present the actual specifics might lower your car’s warranty claim period.

But they can’t be interchanged between each other like other oils especially in North American region high temperatures and as a car owner, you should go your European market factory fill car owner’s manual recommendation always in gasoline and diesel engines low speed pre ignition. Do let me know if you have tried other oil or other oils in a older models.
