Nowadays, the automotive chemicals market offers consumers a fairly large assortment. You can choose from a huge number of products of different purposes, quality and manufacturer. In addition to the fact that there are manufacturers who work only in the auto chemical industry, you can often find products from different factories that produce cars. Basically, they present the choice of products suitable for cars of their brand, but often in the recommendations of this or that oil you can see that it is also suitable for other brands of cars. General Motors is one of them. Their products are also suitable for a number of cars that did not come off the assembly line of this company.

History of General Motors
General Motors is one of the most famous major American automobile companies, headquartered in Detroit. It appeared as a result of the merger of several automobile companies between the late 19th and early 20th centuries. The oldest company was Olds Motor Vehicle Company. At the beginning of the 20th century, several employees of the Olds Motor Vehicle Company started their own business and created the following small companies: Cadillac Automobile Company and Buick Motor Company. And in order not to create competition for each other, they decided to unite. A few years later, a number of other manufacturers joined this corporation, one of which was Chevrolet. The expansion of the company benefited it, as its staff was replenished with talented people who founded a number of new technologies for that time. General Motors began producing automotive chemicals as a result of the company's rebirth after bankruptcy.

Features of GM Dexos2 5W-30 lubricants
Now we will consider GM Dexos2 5W-30. Despite the fact that the headquarters of General Motors is located in the United States of America, the production of lubricants is located in Germany. API approval - SM and CF means that this oil is excellent for both gasoline and diesel engines, respectively. If the oil you purchased has the prefix “Longlife,” this means that the oil has a slightly longer lifespan. Dexos2 can also be safely used for cars whose exhaust system has a particulate filter in its design.
The oil contains a number of different motor additives, which, thanks to their addition at the factory, perform all their functions. One of them is detergent and antioxidant additives, which prevent premature wear of engine parts.
Description of oil
Motul Specific 5w-30 dexos2 belongs to the so-called “classic” synthetics. That is, it is a completely synthetic product made on the basis of polyalphaolefins. In other words – PAO-synthetics. Petroleum products of the highest purity are used as a base.
This lubricant also contains modern additives with reduced ash content - Mid SAPS. This means that the finished product contains less sulfur, phosphorus and sulfated ash than traditional oil. It is on this indicator that the cleanliness and functionality of additional exhaust gas purification systems – particulate filters, catalytic converters and others – depend. This same property makes the product more environmentally friendly. After all, the better the cleaning systems work, the less sediment they contain, the less harmful emissions enter the atmosphere. Which means the better for the environment.
It is also worth noting the high stability and reliability of this engine oil. It is resistant to temperature and adverse road conditions, to increased loads, and allows the engine to maintain its performance in any extreme situations.
It is fluid and has a constant viscosity, due to which it is quickly pumped and distributed inside the engine, providing it with protection from the first moments of operation - and easy starting in cold weather.
Motul Specific 5w30 also cleans and disperses well, preventing the formation of harmful deposits. At the same time, it does not thicken depending on the amount of soot dissolved in it. According to modern environmental standards, it complies with Euro 4 and 5.

Scope of application
Plastic canister 4 liters
As was already said at the beginning of this review, Motul Specific dexos2 was created specifically for the General Motors specification indicated in the name. Its main purpose is GM-OPEL engines of this specification and Euro 4 and 5 standards, which run on gasoline and diesel, and are also equipped with additional exhaust gas purification systems. These are particulate filters in diesel engines and catalytic converters in gasoline engines.
However, this lubricant is compatible with almost any other type of fuel. These are liquefied petroleum and natural gas, diesel and biodiesel, ethanol and ethanol mixtures. It can also be used in any other brands of vehicles if they have similar specifications.
In addition, it should be noted that this substance can be mixed with other mineral and synthetic lubricants.
Advantages and disadvantages of GM Dexos2 5W-30
In this part, we will look at the specific pros and cons of Dexos2 from General Motors. Let's start with the pros, as there are many more of them:
- availability of purchase;
- Excellent value for money and quality;
- the temperature range allows the oil to be used year-round;
- use of original additives in oil;
- excellent lubricating properties with a small amount of lubricant in the motor.
This lubricant has almost no disadvantages, and most of its buyers agree with this opinion. But there is also a fly in the ointment in this canister of honey. Due to the fact that the oil is of sufficient quality and is sold on the automotive petroleum products market, cases of counterfeiting are regularly recorded around the world. But this is not so scary, if you follow a few recommendations, then you should not have problems with counterfeiting.
Reviews of 5w30 oils and their practical use
Reviews found on the Internet cannot always be trusted, but the following case described most likely took place. Dexos oil, already poured into the engine, turned into a jelly mixture after a short use at -20 ° C. The owner of the car allowed himself to spend a little and took a sample of the product to the laboratory to check its authenticity.
It turned out that it was not a counterfeit product, but now it contained a whole cocktail of impurities. And it is absolutely clear that it got there from the fuel that was used in the car. This situation is quite common for all highly refined synthetic oils. Moreover, not one of the companies has yet been able to unambiguously answer the question of how to prevent contact between oil and fuel, because in theory it should not exist.
On the other hand, it is noted that there are no particular problems in using dexos2 5w30; it reliably and quickly lubricates all engine parts, ensuring easy engine starting. It must be topped up as usual and changed as prescribed by the manufacturer. Reviews that the product turns black seem very strange, because it is not light anyway, and during use, given the detergent properties of this oil, you can expect it to darken even more.
This also explains the burning smell during replacement. But, as a result, many had a clean engine. A good price-quality ratio is also indicated, due to which the lubricant is used in car brands not included in the General Motors list. The disappearance of another brand of oil from General Motors from sale is also being vigorously discussed, all explained by the company’s simple transition to a new generation of its product, which it recommends to its customers.
The lubricant is recommended for use in American car brands. It is completely synthetic. If it is impossible to purchase this particular oil, it can be replaced with synthetic oils of the appropriate marking or 10w40 mineral oil. It is important that it can either be replaced completely or mixed with the specified lubricants, which is not very suitable for other brands of this product.
You can make the replacement at a service station or yourself, using the instructions for the car and the oil. You should know that it is necessary to change not only the lubricant, but also the oil filter. After carefully reading the instructions, you should make sure that you have everything you need at hand, even such little things as rubber gloves.
Dexos 2 5w30 oil can be used for the specified car models. Using it in Mercedes or other foreign brands is possible, but this should be done with extreme caution. Despite the high quality of the product in question, it has serious competition, which so far has nothing to oppose.
How to distinguish a fake from the original
There are no exact recommendations with which you can identify a fake, but you should always pay attention to the following little things when purchasing:
Firstly, if you chose oil through the manufacturer’s official website, then when purchasing you need to compare the colors of the container in which the oil is sold. Pay attention to the sticker; under no circumstances should it come off easily. Also, the expiration date numbers should not be easily erased and should be clearly printed. Well, to protect yourself from purchasing a counterfeit, just follow one simple rule: try to buy such products in trusted or official stores.
We hope that our article helped you understand all the features of automotive engine lubricants from one of the largest automakers, such as General Motors.
What is the difference between oil and mixture?
The main difference is that the blend is made by mixing synthetic and conventional oil.
- Withstands high temperatures.
- Lubricant replacement is done less frequently.
- Engine wear resistance increases.
Artificially created mixtures undergo a complex production process, which increases the cost. Changing a car oil costs on average about $20 , and replacing synthetic oil costs almost $80 .
