There are a lot of oil producers, but all of their products differ in quality and efficiency. It turns out 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 around the world (including car brands), so the GM 5W30 oil is suitable for many brands of cars.
In the manufacture of GM, innovative technologies were used, thanks to which the product gained popularity in Asia, Europe, America. GM engine oil is one of the few that is able to maintain its properties for a long time. This allows the driver to save money. the required replacement period is delayed. Also, with this lubricant, fuel consumption is reduced, as well as wear of parts and friction pairs of the engine.
Judging by the reviews of car owners, many drivers return to using this product after they uploaded it at least once.
Characteristics
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 allow you to maintain the performance characteristics of the product for a long time.
Note that two companies produce this oil - General Motors and Motul Specific. They work closely together, 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 manufactured before 1980. With old motor alloys, GM oil undergoes an oxidation reaction, which entails the first smell of burning, 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 generally around the world. The instructions for many cars indicated by the manufacturer that this product must be used for normal operation of the motor. Here is a list of automotive concerns that classify this oil as recommended: BMW, Opel, Mercedes, Chevrolet, Daewoo. But also the owners of Renault, Ford, Cadillac use this product quite successfully - they write about this in reviews at various auto forums.
GM 5W30 oil has many certificates and approvals from car manufacturers, which indicates high quality and compliance. It does not leave precipitation when used correctly, does not freeze, does not contribute to rapid engine wear and does not go into 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, the oil perfectly fulfills its term and with mileage of 10 thousand kilometers is not satisfactory. After 10 thousand kilometers, it may require refilling, although after this period it is advisable to change it to a new one.
What does 5W30 mean in the name?
5W30 is a designation of the type of oil and its operating temperature range at which it will not lose its viscosity. In this case, 5W30 indicates that the grease will work efficiently 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 replaced winter and summer greases from the market, which must be replaced every season.
Benefits of GM 5W30 Oil
This synthetic product is very popular among car owners of European and even Russian production. It provides excellent performance over time and at radically high temperatures.
Benefits:
- The product has a high degree of aeration resistance, due to which air bubbles do not enter the oil. This permanently preserves its beneficial properties and qualities.
- It has a positive effect on the efficiency of the motor. Oil boosts it, albeit slightly. But this is good, since many oils not only do not increase the efficiency of the engine, but often lower it.
- The product prevents the appearance of soot, sulfur, ash and other sediments, reduces the percentage of emissions of harmful substances. All this is achieved through the use of special additives in the oil.
Drivers also note that when switching to this product, they stopped burning. And although most often a decrease in the oil level while driving indicates a poor condition of the engine, there are times when the oils burn and evaporate at high temperatures. With GM 5W30 engine oil, this will not be the case if the engine is working properly and there is no gap between the cylinder walls and the oil scraper rings.
GM oil 5w30 Dexos2
GM produces special grease tolerances that must be applied to the engines of this manufacturer. The list of engines for which oils must be approved also includes Ecotec motors.
GM 5W30 Dexos2 oil is a synthetic lubricant that is produced in compliance with all automotive industry requirements. In the manufacture of this oil, the requirements for fuel economy and the protection of the engine from clogging with exhaust gases are taken into account. Here the content of phosphorus and sulfur is minimal, due to which the resource of the filtering components is increased, and they are known to be expensive. The manufacturer declares that the product meets all international quality standards. Anyway, the oil itself is a Dexos 2 technology standard for other oils with a viscosity of 5W30.
Given the fact that General Motors is a producer of oil, no approvals are required for the group's manufactured vehicles. 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 cleaning of the engine from fuel combustion elements. Despite the low quality of gasoline at many gas stations, this motor lubricant retains its performance characteristics for a long time and protects the engine during its service life.
Technical specifications
Technical characteristics of GM 5W30 Dexos2 oil:
- Viscosity 5W30. Viscosity Index: 146 units.
- Ignition temperature: 222 degrees (this indicates a very low likelihood of an outbreak).
- Density at a temperature of +20 degrees: 853 kg / m3.
- Pour point: -36 degrees.
- Alkali content: 9.6 mg.
Positive reviews
GM 5W30 oil collects both positive and negative reviews. Satisfied drivers note the absence of any engine problems after using this grease. Oil does not go into waste, and its level does not change from replacement to replacement. The only change is the color, which is getting a little darker, but that's completely normal. The darkened oil indicates the presence of detergents, which “capture” deposits on the cylinder walls. With GM oil, the car drives smoothly and quietly, there are no problems starting the engine in cold weather.
Negative reviews
As for the negative reviews, some car owners highlight the absence of any visible changes in the engine after changing the old oil to GM. Given the higher cost of this product compared to other oils and the absence of changes in work, the logical question is: why overpay? Customers also highlight a huge number of fakes in the market. Since the product is very popular, it is faked quite often. Therefore, it is sometimes very difficult to buy an original - it is simply hard to find and recognize.
However, there are much more positive reviews about the product.
Conclusion
GM 5W30 Dexos2 is an effective lubricant that best excels in Ecotec engines. The product is good enough, as indicated 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, so on older engines the lubrication efficiency will not be high. However, in the assortment of GM there are even oils for old engines with high mileage.
