Everyone has heard of Mobil 1 0W40 engine oil. When it comes to engine lubricants, the name of this brand is almost always mentioned. This product is widely distributed in Russia and Europe and is popular. This is not to say that the oils of this manufacturer are the best on the market, but they collect a lot of positive feedback. The characteristics of Mobil 1 0W-40 engine oil and other lubricants of this brand suggest the ability to operate this product in difficult conditions and at almost any temperature that can be in Russia.

Features

Let's start with the fact that in the manufacturer's product line with a viscosity of 0W40 there is only one oil - this is Mobil 1 FS 0W-40. This is a fully synthetic product that will not only provide effective lubrication of friction pairs, but also increase engine life. Note that the manufacturer uses trisynthetic technology for the production of this oil, which was patented by Mobil 1 40 years ago.back. During all this time, many car owners were able to evaluate the quality of oils from this manufacturer, and most of them were satisfied.

Company representatives recommend using Mobil 0W40 on turbocharged engines. That is, the product is intended to work under increased loads. It is also ideal for new engines, although this is not so much the oil itself, but its synthetic base.

What does 0W40 mean on the label?

There are summer, winter and all season oils. Summer ones are indicated by a number (for example, 30), which shows at what air temperature above zero the oil is able to maintain its fluidity and work normally. Winter are designated by the letter "W" (Winter) and a number. The lower the number, the lower the performance of the oil can work.

Mobil 0W40 has two markings. This means that this oil is multigrade and can work equally well at high and low temperatures. That is, in the range from -30 to +40 degrees of air outside, the oil will retain its viscosity, so it will ensure a smooth start of the engine even in a cold winter.

Laboratory studies

The company says that the product is subjected to various tests every year, so that its quality can be kept at a high level. Therefore, the oil always meets international standards.

According to the latest clinical trials,it can be concluded that the oil retains its performance properties for a long time, reduces gasoline consumption. As a result of the use of lubricant in the motor, much less carbon deposits and deposits are formed, which harm the engine itself and the environment.

Fuel economy

According to the company's engineers, on average, cars after switching to Mobil 1 0W40 oil consume 3% less fuel and emit less harmful substances into the environment. Of course, 3% is not much, but given the high mileage, a substantial amount is accumulated that can be saved with this oil.

Note that the product was previously called Mobil 1 0W40 New Life, but later its name was changed to FS 0W-40. That's what it's called now. After this change in name, laboratory tests of the oil composition always showed a viscosity index of 186. This means that the grease will not thicken at -35 degrees and will not lose viscosity even at +140 degrees.

Also contains a large amount of boron, which increases the effectiveness of anti-wear and detergent additives. Phosphorus and zinc are also used to reduce wear. All these elements were added to oils 70 years ago, and they are still the main anti-seize and anti-wear components.

Pros

When comparing Mobil 0W40 oil with synthetic or semi-synthetic oils from other manufacturers, the former will have some advantages. WhatAs far as mineral oils are concerned, there are much more pluses here. Actually, the following advantages can be distinguished:

1. The product can be used on any car. However, it is recommended for new motors. Older, higher mileage engines will have lower oil performance.
2. Stability with temperature fluctuations outside the window.
3. Protection against wear of engine parts.
4. High level of motor cleanliness inside.
5. Cleaner exhaust gases.
6. Increases engine life.
7. Maintain viscosity at low and very high operating temperatures.
8. Efficient operation even at maximum loads (at maximum rotation speed).
9. Ensure fuel economy.
10. Low cost.

However, it cannot be reliably stated that the driver will receive all these benefits by filling this product into the engine. For example, on old engines with high mileage, synthetic oil will not show all efficiency, and it is unlikely that it can increase the life of an old engine. Therefore, you should not expect "healing" of the old motor.

The problem with fakes

One of the main drawbacks of the product is its popularity and high consumer demand, which is why many fakes have appeared on the market. Almost any seller has a non-original batch of Mobil 0W40 oils, which he successfully and quickly sells. And although many drivers do not notice the difference between a fake and an original at all, motorssome cars are sensitive, and the lack of non-original oil immediately affects them: the lubricant goes to waste, the noise of the engine is felt, the car loses momentum, etc.

Therefore, when choosing, attention should be paid to packaging - only it can be used to determine whether a fake is in front of you or an original product. At a minimum, the canister should be made of good plastic, without coarse seams. The same applies to the lid, the sticker on the canister should sit evenly and not tear off. It is difficult to tear off the sticker from the original oil canister - it will never come off completely. But on non-original products, stickers sometimes slip off by themselves. You need to buy oil only in trusted stores, and not in service stations or markets where it is bottled from large barrels with unknown contents.

Customer Reviews

Various quality certificates do not always reflect the actual performance of the oil. More accurate about it say the reviews of customers who use it for a long time.

Most car owners who fill in oil from a French manufacturer admit that during the operation of the product, their cars began to better cope with everyday tasks. That is, cars began to consume less fuel (not everyone talks about this), they added mobility, and the engines began to work quieter and softer. In some cases, oil burnout stopped, but not immediately, but after two or three replacements.

As for the prevention and increase in engine life, this one from the reviewsno way to know. After all, not a single car owner knows what engine resource he has and how much oil could increase this resource. So here we have to take the word of the manufacturer. However, they all claim that their oils make engines run longer.

Conclusion

Mobil 0W40 oil, the characteristics of which allow it to be used in any season in Russia, should be given credit. The car really starts even at -30 degrees, and the oil does not lose its declared viscosity at all at this temperature.

The only drawback is fakes. Beware of them.
