This synthetic material does not freeze even at temperatures below 20 °C. The viscosity changes according to weather conditions, thereby ensuring trouble-free operation.

The viscosity of Mobile 5W40 varies depending on weather conditions

It is suitable even for extreme driving at long and short distances. Due to work powerful motors the lubricant is exposed to elevated temperatures, which to some extent increases the thermal load on it. Higher temperature regime leads to a decrease in the amount of harmful emissions and thereby contributes to the entry of large amounts of soot into the lubricant.

It has very low level volatility, therefore the consumption and amount of waste substances is significantly reduced. Mobil 5W40 is a high-quality synthetic that belongs to the very high class lubricants. It is fully compatible even with mineral modifications.

Mobil synthetics are used to improve the performance of diesel engines with very high technical indicators, including modern models engines with low emissions. This Mobil engine oil is suitable for engines of vehicles that operate at fairly high speeds and under very heavy loads, for example, for engines of heavy off-road equipment.

This oil perfectly combines the required viscosity, detergency, volatility and lubrication; in addition, it provides maximum reduction in friction of parts and low consumption. It is also worth noting that Mobil engine oil is completely safe to use. Mobile's price is quite affordable, which is why you can get excellent quality at a good price. All this makes him a leader among similar oils other companies.

The modern market offers huge variety motor oils. Moreover, such products, in fact, differ from each other only in the base (mineral, synthetic or semi-synthetic) and additives. It is the latter that largely determine the technical characteristics of the product and its interaction with the engine.

Mobil 3000 5w40 motor oil has a synthetic base. This material is intended for different types engines operated at any time of the year.

7. It does not thicken in cold weather, lubricating all parts evenly and making it easier to start the engine at low temperatures.
8. Suitable for use in various types cars and engines.

As for the shortcomings, there may not be any if you use motor oil for its intended purpose - that is, pour it only into those cars whose manufacturers recommend a product with exactly these characteristics. Carefully study the specifications before choosing a lubricant, and then the risk unpleasant consequences will be minimal. If all the conditions are met, but the result is not satisfactory, then there is a high probability that you have come across a fake. Read on to learn how to distinguish it when choosing motor oil in a store.

How to spot a fake

Mobil 1 x1 5w30, like other Mobil products (especially synthetic ones), is one of the most frequently counterfeited. Motor oils- This is generally a magnet for all kinds of scammers. And while manufacturers are coming up with new ways to protect their products, dishonest businessmen are not sitting idly by either. As a result, counterfeit products are increasingly difficult to distinguish. However, difficult does not mean impossible.

So, our hero has a special lid, which can only be opened according to a special pattern that is applied to it. At the same time, the watering can extends for easy pouring of oil. Making such a cover requires expensive equipment, and it is extremely difficult to counterfeit.

Label on the back of the canister original oil consists of two layers, one under the other, and the arrow in bottom corner talks about it. With real oil, the top layer peels off easily and goes back on. A fake label often has a single layer, and if it has two layers, the top one doesn’t peel off well and can smear the text on the bottom one.

And in general, we can say that the quality of the packaging of the fake is poor. The plastic is rough, uneven, the labels are glued unevenly, the text is smeared and printed with errors. Specifications and approvals may also be missing.

As the engine operates, oxidation products, carbon deposits, and harmful deposits accumulate in it. It's unavoidable. All these deposits in the engine increase friction, and this naturally leads to deterioration in engine performance. As a result, it begins to work under heavy loads, which leads to rapid wear details. Therefore, for engines with high mileage recommended special oils, which are aimed at protecting the motor from wear and cleaning from carbon deposits. Mobil provides drivers with enough big choice. The range also includes lubricants for power plants with high mileage. The most effective is

Description

This product is made entirely on a synthetic base with the addition of special cleaning additives, which is necessary for older engines. Like any other synthetic base, this one is also aimed at cleaning the engine from carbon deposits, sludge and soot. The advantage of synthetics is support and stable work even at lower temperatures compared to mineral oils.

Note that earlier this product bore two names: Mobil 1 Rally Formula 5W50 and Mobil 1 Peak Life 5W50. Now it's a slightly different lubricant with an improved formula. The oil retained all the advantages of the previous version and acquired new ones positive traits. Now the lubricant meets modern international quality standards.

Special properties

In addition to its cleansing and dispersing properties, the oil reduces the harmful effects when using unstable and low quality fuel, prevents wear and tear on the motor, which increases its service life.

Also, the product retains its viscosity throughout its entire service life, and from replacement to replacement it remains stable. True, this is only true in cases where the engine is working properly. When mixing oil with antifreeze, for example (this happens), its viscosity and lubricating properties change, but this is not the fault of the product itself. Also, this lubricant evaporates slightly, so it is consumed quite economically and even helps save fuel. The product is also resistant to temperature changes and vehicle overloads, and can work successfully even in extreme conditions.

Application area

5W50 is designed for engines passenger cars, however, it is recommended to fill it into those engines whose mileage exceeds 100,000 km. It is ideal for cars European brands And large concerns Porsche type.

Characteristics of Mobil 5W50

The most main characteristic of this oil - its viscosity indicated in the name (5W50). What does this marking say? Firstly, the number 50 in the name means that the product is summer and works well at high temperatures. Secondly, the 5W value indicates its winter destination. This makes it clear that the oil works well in cold weather and has normal viscosity at negative temperatures. This means that 5W50 is all-season and does not need to be changed every time it gets cold or warm.

Operating temperature range

And now in more detail. The number 5 in the name shows how low temperatures the oil can operate normally. The lower the number, the lower the temperature limit. Index 5 is not the lowest, but it makes it clear that the oil will not lose its viscosity and will ensure normal engine starting at a temperature not lower than -32 degrees.

The number 50 in the name shows at what maximum ambient temperature the oil will work stably. IN in this case the upper limit is 50 degrees. That is Mobil product 5W50 operates in a temperature range from -32 to +50 degrees. There are not many oils that can operate over such a wide temperature range.

Similar Mobil 5W50 allow it to be used in any weather conditions and in almost all regions of Russia. Even in those where the temperature drops to -30 degrees. Of course, in very severe frosts, which are observed in the North, oil is not able to provide normal lubrication of friction pairs. But the lubricant itself is resistant not only to ambient temperatures, but also to engine overheating.

Technical Mobil specifications 5W50 are ideal for cars Russian production. In VAZ cars, the oil efficiency is quite high, and even quite old engines run well and smoothly on it. Of course, when using this lubricant, you need to be careful when pouring it into very dirty engines. Intensive cleaning can cause filters and valves to become clogged with carbon particles.

Advantages and disadvantages

Mobil 5W50 is an excellent synthetic oil that is temperature resistant and effectively cleans engine contaminants. It has certain advantages compared to semi-synthetic and mineral lubricants.

Advantages:

1. Excellent lubricating properties. All rubbing pairs of the engine are effectively lubricated, the oil forms an oil film of the required thickness and maintains the required viscosity throughout its service life. Temperature fluctuations and even dispersed particles do not particularly affect the viscosity of the lubricant.
2. Cleaning properties. Thanks to the content special additives The oil in its composition cleans all parts of the engine from soot, sludge and carbon deposits, and prevents the formation of new particles. All this reduces engine wear and significantly extends its service life.
3. Economical. Unlike many other oils, it practically does not waste, and its level does not change from replacement to replacement. But this is only true for those engines that do not “eat” oil on their own. If there is a problem with the engine, then it will “eat up” even the most high-quality lubricant. Mobil 5W50 also helps save fuel by reducing the friction force of parts.
4. High resistance to temperature fluctuations. The oil is universal, and that says it all. It retains its viscosity at subzero temperatures and in extreme heat, so it will ensure engine starting in any weather conditions.

Does this oil have any disadvantages? They cannot but exist. Modern engines have long ceased to exist simple mechanisms. They look more biological human organisms, so we can’t say for sure whether it will fit this lubricant specifically for your car. However, Mobil 5W50 is actively used by both owners of old foreign cars and car owners Russian automobile industry. It is also poured into cars produced in 2005-2010.

Fakes Mobil 5W50

Some buyers of this product remain dissatisfied with its quality. But this is often due to the fact that buyers use it in inappropriate conditions or purchase a fake. In the first case, the owner himself is to blame, in the second - the scammers. To be frank and honest, scammers deserve respect. Even them non-original oil, which is sold in 90% of stores, works very effectively and is often no different from the original. So sometimes you shouldn't worry about it at all.

You can distinguish a fake only by the packaging, label, lid:

1. Cracks and chips on the packaging are the first sign of a fake. The plastic may have a wavy structure and must be smooth.
2. The second sign of a fake is a poor-quality label. The text may not be printed well, and there may be adhesive residue visible around the label.
3. Lid. In the original packaging, it opens according to a special pattern, and when opened, a watering can appears. Fakes may not have all this.

The original oil canister is silver with a blue tint and has a darker blue lid. The back label has 2 layers. It is also worth noting that Mobil 5W50 oils are produced in Europe. In Russia there may be products manufactured in Sweden, Russia, Finland. There are no factories in Russia where this oil is made.
