Saving money

The manufacturer announces that by acquiring thismotor fluid, the driver will be able to save money. This is due, at least, to the fact that the oil, although it is an expensive material, but it completely protects the engine components. In addition, the quality liquid GM 5W30 (the characteristics described below) allows you to extend the life of the car parts. After all, the better the oil, the longer the operation period, each component of the engine works. The fluid allows you to increase the time between scheduled maintenance.

These indicators are really real.Consumers confirm significant savings after stable use of the described oil. This nuance is another reason for the popularity of liquid on the market.

Main technical characteristics

In the title you can see 5W-30.This indicates which type of viscosity the liquid belongs to. The substance is considered energy-saving. Alkalis in the motor fluid is 9.6 mg. Due to the special composition of this oil is capable of special results. It shows excellent lubricating characteristics. This ensures a long and non-stop working period of all engine components. If you take the average temperature of 20 ° C, then the approximate density of the liquid GM 5W30 (reviews read below) was 853 kg per cubic meter. The viscosity index is 146 units. When the ambient temperature drops to -36 ° C, the oil freezes. This indicates that in this weather is unlikely to get a car. The viscosity of the liquid when the engine is operating at +100 ° C is 11.2 mm² for a second. If to speak about +40 ° С, this mark rises and is equal to 66 mm²/ sec.The oil can ignite if the temperature rises to + 222 ° C. That is why the risk of such a danger is almost minimal, since the engine does not heat up to such a high level.

additional characteristics

The main property of engine oil is itsthe ability of resistance to the ingress of air, - says the manufacturer. Accordingly, due to the use of a certain new technology, the described liquid is not capable of letting foam and bubbles. It is also often used not as a motor, but as a hydraulic one. Oil is able to guarantee a powerful and smooth start of the machine. If we talk about the oxidation of any components, then it should be noted - the liquid prevents this process.

However, like all motor oils, GM 5W30(reviews of most motorists laudatory) has its drawbacks. One of these is friction (or overheating). Unfortunately, even a high-quality oil cannot protect against such effects. And they, as is known, most often lead to engine breakdowns. And we are talking about both old and modern engines.

When overheating occurs, it formshydrogen. He for some time, however, falls into the metal components of the power device. It is destructive for him. Wear may occur from too fast a breakdown of metal parts. This often leads to additional repairs.

Positive feedback from consumers

Those who fill in the described oil for the first time, notices that the motor behaves much quieter, the car became sharper when driving on the road. Claims to work no one practically.

Many consumers, before moving onThis oil, read about it on the forums, where experienced drivers discuss high-quality fluids. Often, buyers do not pay attention to negative reviews in networks and still acquire motor substance. And they all notice that the car is going much better, nobody changes the oil ahead of time, because there is no need for that.

In general, all consumers are satisfied with the purchase, exceptvery small percentage. It is best to purchase from the official supplier of really original liquid, in which quality you can be 100% sure. If the consumer takes a fake, then nothing good will happen. All car owners recommend GM oil Dexos2 5W30. How to distinguish a fake from an authentic liquid will be described a little below.

Negative consumer feedback

Some buyers do not notice the difference in workengine with this oil and other species, the price of which is much lower. It is unlikely that someone likes to overpay for the same results. However, this can be argued feature of the engine.

Some consumers write that the car with thisoil does not start at -40 ° C. This is a significant drawback, because if you urgently need to come somewhere, you will have to fill in the additive. This action can be very harmful. However, it should be noted that the manufacturer indicated in the characteristics: at temperatures below -35 ° C, the liquid freezes. Therefore, it is necessary immediately before purchase to estimate the probability of occurrence of force majeure. Otherwise, money can be called wasted wind.

Many people notice that when you drain the oil itacquires a dark color, a precipitate appears. Moreover, buyers who noticed this claim that the article made it clear that the liquid was not a fake. GM 5W30 for certain drivers leads to clogging of pipes.

Conclusions based on all feedback.

From consumer reviews it becomes clear thatoil is quite popular and common. Even with the fact that there are negative comments on the Web, products are in demand, and this already speaks of its quality. The majority of drivers, having tried the oil at least once, no longer use other liquids. Especially in some cases it is the most cost-effective and saves money. Not all motor fluids can be proud of the same characteristics and properties as oil from a global manufacturer.

But also dissatisfied with this liquid is enough. Mostly negative is directed towards high cost. On the territory of the Russian Federation, the average price is 2 thousand rubles for five liters in a canister. Since the fake GM 5W30 oil is quite popular, consumers often face counterfeit products.

What to look for when buying?

In order not to buy a fake, you shouldpay attention to the canister. You also need to check the cover for tightness closure to be sure of the contents. There are some craftsmen who simply replace the oil with other similar liquids. Naturally, talking about the quality of the latter is not necessary.

Often, a fake is revealed on two accounts, if you know what the original packaging looks like. The following describes all the differences.

Stitches and plastic

Many are interested in buying such a motorfluids like GM oil 5W30 Dexos2. "How to distinguish a fake?" - One of the most pressing issues. This can be done by paying attention to how the seams are made and of what quality plastic.

In the original canister, all connecting elements are not visible, there are clear and convex shapes, seals and holograms are applied. The container itself is made of fairly dense plastic.

With a fake version, the material is so softwhich is capable of deforming even from simple pressing. And in the original form of plastic is not returned. If you take the canister to the light, you can see how much liquid there is in the container. Holograms are vague or absent. Stitches noticeable, rough. At the bottom you can find notches.

Lot series

For long-term car operation, the main thingpurchase high-quality and original oil GM 5W30 Dexos2. How to distinguish a fake on a batch series? For a long time, drivers, who themselves are able to detect underground oil, know that the “Chinese” are rather ill with arithmetic. The original number of the series consists of seven numbers - they include the batch, date of preparation and expiration date. Counterfeit oil can have a serial number of five or even eight numbers. This immediately speaks of its poor quality.

Color Coat

We continue to choose only high-quality oil GM5W30. How to distinguish a fake by the color of the container? The canister from the original manufacturer has a gray color, without streaks, there are no transitions in shades. If the listed features are still present, then you can immediately understand - this is a fake. Also, all the cans from the manufacturer are smooth. At the same fake surface of the container is rough, which gives a certain color effect.

Hologram

In the right corner on the left side of the original packaging.there is a hologram. If it is located in a different place or is completely absent, it means that GM Dexos2 5W30 oil is fake. If suddenly the seller decides to convince the buyer, they say, this is a factory mistake, then you should not believe this. The hologram is affixed to the conveyor, which is not able to constantly apply it to different places of the canister.

Extra details

On the back of the container there should be nothing. It is smooth and clean. The manufacturer does not write anything on it and does not print. On fakes, the line in this place is often punched with yellow or orange color. Unfortunately, even professionals cannot determine what it means.

PLYSU caption

If at the bottom of the canister at the top left consumernotices PLYSU inscription instead of a hologram hourglass, you can immediately choose another store to make a purchase. She clearly says that oil is a fake. The inscription itself is printed in thick font.
