There are a lot of oil producers, but all their products differ in quality and efficiency of use. It so happens that Japanese or Korean oils are better suited for Korean and Japanese cars, European oils for European cars. General Motors is the holder of many brands from around the world (including car brands), so the GM 5W30 oil produced is suitable for many car brands.

In the manufacture of GM, innovative technologies were used, thanks to which the product gained popularity in Asia, Europe, America. GM motor oil is one of the few capable of retaining its properties for a long time. This allows the driver to save money, because. replacement period is delayed. Also, with this lubricant, fuel consumption is reduced, as is the wear of parts and engine friction pairs.

Judging byfeedback from car owners, many drivers return to using this product after filling it at least once.

Features

This synthetic product is obtained from extracts of selective purification of masses from petroleum oils, then distillate oils and a solution containing phosphorus, chlorine, molybdenum disulfide are added. All these additives help to maintain the performance of the product for a long time.

Note that two companies produce this oil - General Motors and Motul Specific. They work closely with each other, creating all-weather lubricants. The product line of these brands is very large, and in it you can find oil that is ideal for any car. However, experts advise not to use it in conjunction with engines in cars that were produced before 1980. With old engine alloys, GM oil enters into an oxidation reaction, which entails first a burning smell, and then the knock of engine parts.

GM 5W30 oil is one of the most popular in the series and is actively used in Russia and all over the world. In the instructions for many cars, the manufacturer indicates that this product must be used for the normal operation of the motor. Here is a list of automotive concerns that include this oil in the recommended list: BMW, Opel, Mercedes, Chevrolet, Daewoo. But also the owners of Renault, Ford, Cadillac use this product quite successfully - they write about it in reviews on various auto forums.

GM Oil 5W30has many certificates and approvals of automakers, which indicates high quality and compliance with the requirements. It does not leave deposits when used correctly, does not freeze, does not contribute to the rapid wear of the engine and does not go to waste. With all the positive qualities, the price of GM 5W30 oil is 1600-1700 rubles for a 5-liter canister. This means that the product is not more expensive and sometimes cheaper than the products of well-known European brands. At the same time, GM is not inferior in quality. If you believe the reviews of car owners, then the oil works out its life perfectly and does not cause any complaints with a run of 10 thousand kilometers. After 10 thousand kilometers, it may require topping up, although after this period it is advisable to change it to a new one.

What does 5W30 stand for in the title?

5W30 is a designation for the type of oil and its operating temperature range, in which it will not lose its viscosity. In this case, 5W30 indicates that the lubricant will work effectively at -35 degrees as well as at +50. This means that GM 5W30 engine oil is multigrade. However, now almost all oils are universal. They quickly forced winter and summer lubricants out of the market, which must be replaced every season.

Advantages of GM 5W30 oil

This synthetic product is very popular among car owners of European and even Russian production. It provides excellent performance over long periods of time and at radically high temperatures.

Benefits:

1. The product has a high degree of aeration resistance, which prevents air bubbles from entering the oil. This preserves its useful properties and qualities for a long time.
2. Has a positive effect on the efficiency of the motor. Oil increases it, albeit slightly. But this is also good, since many oils not only do not increase the efficiency of the engine, but often lower it.
3. The product prevents the appearance of soot, sulfur, ash and other precipitation, reduces the percentage of emissions of harmful substances. All this is achieved through the use of special additives in the composition of the oil.

Drivers also note that when they switched to this product, their burnout stopped. And although most often a decrease in the oil level while driving indicates poor engine condition, there are times when oils burn out and evaporate at high temperatures. With GM 5W30 engine oil, this will not happen if the engine is working properly and there is no gap between the cylinder walls and oil scraper rings.

GM Oil 5w30 Dexos2

GM issues special approvals for lubricants that must be used in this manufacturer's engines. The list of engines for which oils must have approvals also includes Ecotec engines.

GM 5W30 Dexos2 oil is a synthetic lubricant produced in compliance with all requirements of the automotive industry. In the manufacture of this oil, the requirements for fuel economy and protection of the engine from exhaust gas clogging are taken into account. Here the content of phosphorus andsulfur is minimal, due to which the resource of filter components is increased, and they are known to be expensive. The manufacturer claims that the product meets all international quality standards. And in general, the oil itself is the Dexos 2 technology standard for other oils with a viscosity of 5W30.

Given the fact that General Motors is an oil manufacturer, no approvals are required for the concern's produced cars. This means that GM engine oil can be safely poured into Chevrolet, Buick, Alpheon, Cadillac, Opel, Pontiac, GMC cars.

The product itself is suitable for both diesel and gasoline engines. It contains additives aimed at high-quality engine cleaning from fuel combustion elements. Even despite the poor quality of gasoline at many gas stations, this motor lubricant retains its performance for a long time and protects the engine during its service life.

Technical parameters

1. Viscosity 5W30. Viscosity index: 146 units.
2. Ignition temperature: 222 degrees (this indicates a very low probability of a flash).
3. Density at +20 degrees: 853 kg/m3.
4. Pour point: -36 degrees.

Positive Feedback

GM 5W30 oil collects both positive and negative reviews. Satisfieddrivers note the absence of any problems with the engine after using this lubricant. The oil does not go to waste, and its level does not change from replacement to replacement. The only change is the color getting a little darker, but that's perfectly normal. Darkened oil indicates the presence of detergent additives that "capture" deposits on the cylinder walls with them. With GM oil, the car drives smoothly and quietly, and there are no problems starting the engine in cold weather either.

Negative reviews

As for the negative reviews, some car owners point out the absence of any visible changes in the operation of the engine after changing the old oil to GM. Given the higher cost of this product compared to other oils and the lack of changes in work, the logical question is: why pay more? Also, buyers highlight a huge number of fakes on the market. Since the product is very popular, it is counterfeited quite often. Therefore, it is sometimes very difficult to buy the original - it is simply difficult to find and recognize it.

However, there are many more positive reviews about the product.

Conclusion

GM 5W30 Dexos2 is an effective lubricant that performs best in Ecotec engines. The product is quite good, as evidenced by tolerances, quality certificates and customer reviews. But it should be borne in mind that oil is not a panacea for the "diseases" of the motor, therefore, on old engines, work efficiencylubrication will not be high. However, GM even has oils for older engines with high mileage.
