history of the company

General Motors is one of the most popular and well-known automobile companies in the world. The main office is located in the city of Detroit. The company owes its appearance to the process of merging several companies at the same time in the late 19th and 20th centuries. At the beginning of the last century, several employees of the Olds Motor Vehicle Company decided to create their own automotive business. Thus, there were small companies called Cadillac Automobile Company and Buick Motor Company. But it was unprofitable for them to compete with each other, so a merger took place.

The new brand quickly grew and developed. A few years later, other small car manufacturers joined the large corporation. So Chevrolet became part of the concern. The inclusion of new entrants into the market was an advantage for GM, as more and more talented designers were added to the workforce, who designed many of the popular cars of the day.

Throughout its history, the concern has been developing and producing new car models. However, after the bankruptcy of General Motors, in addition to its core business, it began to pay more attention to the production of special chemicals for car care.

Which cars can use Dexos2 5W30

Engine oil GM 5W30 Dexos2

This oil is a modern lubricant suitable for use in all models of General Motors vehicles. For example, this applies to brands such as Opel, Cadillac, Chevrolet. Due to its fully synthetic composition, the fluid is suitable for all types of engines, including those equipped with a turbine. Due to the excellent combination of additives and main components in the oil, long-term operation of the power unit is achieved and the time between lubricant changes is increased.

In addition to the already designated automotive brands, the lubricant is also suitable for use in Holden sports cars. The list can be replenished with Renault, BMW, Fiat, Volkswagen models. Yes, and some motorists of companies involved in the production of military equipment, do not hesitate to try this lubricant.

A large number of additives in the composition and the versatility of the oil make it possible to adapt the oil for use in domestic conditions. This circumstance made dexos2 oil popular among motorists in Russia and the countries of the former USSR.

Oil shows its best side even when using low-quality fuel. However, in this case, the car owner is obliged to clearly control the timing of the replacement.

Oil characteristics

The lubricant viscosity mark (5W) is the minimum allowable temperature limit at which the oil can freeze. This value is -36°C. When the thermometer falls below the indicated limit, the car owner cannot start the car. The fact is that after starting the engine, a certain time must pass until the oil pump supplies lubrication to all interacting parts. In the absence of lubrication in the system, the power unit experiences oil starvation. Consequently, the friction between the structural elements increases, which leads to their wear. The higher the fluidity of the lubricant, the faster it can reach parts that need protection.

The number "30" in the GM 5w30 Dexos2 marking means the heat load class when the machine is running in the hot season. Many automakers advise buyers to use grade 40 oils due to the thermal stress of modern engines. Under these conditions, the lubricant must retain the initial viscosity parameter, sufficient for a layer to form between the friction elements, lubricating and cooling them. This circumstance is of great importance for preventing wear and engine jamming in hot weather or during prolonged stay in traffic jams. The same applies to the situation when the engine overheats due to a failure in the cooling system.

The name Dexos2 itself is an automaker's approval or standard that describes the required performance of a lubricant used in GM automotive products.

API Oil - SM and CF approval implies the use of oil for all types of engines. When buying oil with the Longlife prefix, the period for changing the lubricant increases. Dexos2 is also used in cars, the design of the exhaust system of which implies the presence of a particulate filter.

The engine oil in question has the following types of tolerances and specifications:

  1. ACEA A3/B4. It is fixed on the product for high performance diesel units and for gasoline engines equipped with direct injection. Fluid with this marking can replace A3/B3 oil.
  2. ACEA C3. This product is used in diesel engines equipped with a particulate filter and an exhaust catalytic converter.
  3. SM/CF API. Oil with the specified brand is used to facilitate the operation of a gasoline engine manufactured no earlier than 2004, and in a diesel engine manufactured no earlier than 1994.
  4.  Volkswagen Volkswagen 502.00, 505.00, 505.01. This standard defines lubricants with higher stability suitable for all manufacturer's models.
  5. MB 229,51. The application of this sign indicates that the oil meets the requirements for use in Mercedes vehicles equipped with an exhaust gas purification system.
  6.  GM LL A / B 025. Used for vehicles with a flexible service system in the ECO Service-Flex service.

Instead of the former ACEA C3 index, an oil can can contain BMW LongLife 04. These standards are considered almost identical.

Advantages and disadvantages of GM Dexos2 5W-30

Naturally, any motor oil has positive and negative sides. Since the lubricant in question is endowed with a large number of advantages, it is they that should be considered first of all:

  1. Affordable cost;
  2. The relationship between the quality of a product and its price;
  3. A wide temperature range allows the car owner to use the oil all year round;
  4. The presence of original additives;
  5. Providing excellent lubricating properties even with a lack of oil in the power unit;
  6. Ability to use GM 5w30 Dexos in any type of engine;
  7.  Provide effective lubrication even when starting a cold engine;
  8. No traces of scale and deposits on parts;
  9. Ensuring efficient heat removal from the contacting elements, which reduces the risk of engine overheating;
  10. An oil film that remains on the engine walls even under extreme operating conditions;
  11. Reduced fuel consumption compared to mineral motor oils.

The negative aspects of the lubricant in question are practically absent. And this opinion is shared by many motorists using Dexos2 5W30. However, even a rich composition of additives and main components will not protect engine elements from friction under certain conditions.

This applies to engines installed on old models of machines and have already exhausted their resource. With high wear of parts and their constant friction, hydrogen is released, which destroys the metal elements of the power unit.

Other issues that may arise in connection with the use of Dexos2 5W30 oil relate to fluid handling. The facts of illegal oil extraction are everywhere.

How to distinguish a fake from an original

Engine oil GM 5W30 Dexos2

The first batches of GM Dexos2 oil entered the market from Europe. However, oil production began in Russia three years ago. If the former European products were packaged in containers of 1, 2, 4, 5 and 208 liters, then Russian-made oil was packaged in containers of 1, 4 and 5 liters. Another difference is in the articles. Boats of European factories were marked with two positions. So far, domestic products have received only one set of numbers.

We will find confirmation of the quality of the oil in the reviews of satisfied car owners. It runs quieter, the engine responds easily when starting even in cold weather, fuel is saved, and the structural elements of the power unit retain their original appearance. But all this is observed when using original products. Buying low-quality oil will lead to problems starting the engine with the onset of cold weather, the formation of deposits, and the lubricant will have to be changed more often than usual.

In order not to become a victim of a fake, you need to know the characteristics of the original product:

  1. There must be no seams in the Dexos2 container. The container will completely melt, and the seams on the sides are not felt to the touch;
  2.  High-quality, dense plastic is used. In the manufacture of fakes in 90% of cases, a thin polymer is used, which bends without much physical effort and a dent is clearly drawn on the surface;
  3. The front side of the container has a seven-digit serial number. On a fake, this number is written in five or six digits;
  4. The color of the original oil container is light grey. There should be no stains or areas that differ in shade on the plastic;
  5. The plastic of the original product is smooth to the touch, while the fake will be rough;
  6.  There is a special hologram in the upper right corner of the label. It is problematic to fake it, because it is an expensive procedure;
  7.  Double label on the back of the container;
  8.  There are no perforations or tear-off rings on the lid. At the top there are two special notches for fingers;
  9.  The original oil cap is ribbed. The fake is usually soft;
  10.  The legal address of the plant located in Germany is indicated as the manufacturer. Any other country, even European, testifies to a fake.
