Is it possible to mix motor oils: synthetics with synthetics or semisynthetic?

On the road, situations in whichit may be necessary to refill the vehicle with a motor oil. What to do in this case? There are at least 2 ways to solve the problem: ask someone to tow the car to the nearest service station or you can mix engine oils, adding what is available. Which option to choose? What can be the consequences of mixing? Let's understand.

Etymology

Let's start with synthetics. The basis of such oils is an artificial product of oil and gas processing, which is obtained by synthesis. The process of output is very complex, but quite effective. The molecular composition of such oils is so perfect that as a result of its impact on the car parts, there are no oxidative processes, as well as reactions with sealing rubber products. This engine oil is based on special additives that increase productivity and reduce fuel consumption. The only possible drawback of such a product is its cost. Some other masters say that the synthetic oil stinks when the engine is running and goes into a state of exhaustion. This is certainly not known. Therefore, we will consider it untrue.

Semisynthetic oil basically containstwo types of substances of a molecular composition: synthetic and mineral. In simpler terms, this is a mixture of two fundamentals. It is important that there are no standards governing the ratio of the bases in the semi-synthetic oil. Some good brands distribute the components as follows: 40% - synthetics, 60% - mineral base. However, this percentage is always selected at the discretion of the manufacturer, and some unscrupulous brands may go away from the recommended proportions.

Which oils are suitable for which engines?

So, is it possible to mix motor oils? I think no. After all, the two fundamentals have different technical characteristics. Semisynthetic grease has a low viscosity index, has a small additive package and higher oxidation rates. If you use this oil in winter, when there are severe frost outside the window, starting the motor is more difficult, compared to how the engine works on analogues with a synthetic base. Also, the interval of replacement of such oils is shorter. Possible plus semisynthetic oil - low price.

Some experts recommend usingsemisynthetics on older engines, the mileage of which exceeds the mark of 100 thousand kilometers. It will restore the compression, wipe the microcracks and other defects. It is ideal for a motor with an installed turbine.

Synthetic - choice for new engines

As for the synthetic basis, itsrecommend pouring from scratch and use on new engines with a small mileage. This liquid perfectly copes with high temperatures and has high resistance to its fluctuations. To replace such oil it is possible not through 10 thousand kilometers of run, and through 30-35 thousand. A wide range of additives used allows to keep the internal oil channels clean. This oil prevents the formation of carbon deposits, increases the engine's potential and reduces the consumption of gasoline.

Perhaps now it is more clear to us whether it is possible to mix synthetics with semisynthetics. Motor oils on these bases are intended for different engines. This means that you can not mix them.

What will happen when mixing motor oils?

When mixing two different bases, the reaction,the result of their incompatibility will be inevitable. This will lead to the formation of slags that clog the oil channels and make it difficult for the fluid to move through the engine. As a result, the motor wears out quickly, and its service life is reduced. Organic grease has many chemical additives in its composition. They are there to protect the engine. The inorganic base contains additives by default. As a result, when mixed, you get an excessive amount of chemistry, which will not benefit the engine.

When is mixing allowed?

It should be noted that there is no label on any labelthe official tolerance of the manufacturer for mixing. Negative consequences in this case will certainly be, so no one will give the go-ahead for such manipulation. But since the misfortune befell, and there is no other way out, it is possible to add some organic to synthetics or vice versa. But after you do this, you must immediately follow the nearest service station, and try not to turn the motor. In the car repair shop it is necessary to completely rinse the engine and pour the "native" oil recommended by the manufacturer.

So can you mix engine oils with cautionon fast washing of the motor? This is allowed, but strictly not recommended. As for the washing, it should be done at the SRT using special means.

Is it possible to mix synthetics with synthetics?

Synthetic-based motor oils are lessare capricious. However, there is no universal lubricant with one viscosity and one additive package. Each manufacturer makes its own synthetics, which includes different additives. Mixing synthetic oils of different brands, one can not exclude the reaction of incompatibility. At a minimum, some additives may precipitate, which will drastically reduce the lubricating properties of the oil, making it more viscous. However, mixing oils on one basis is better than trying to mix different bases. However, it is worthwhile to ensure that the viscosity of the lubricants is the same. Some drivers are wondering whether it is possible to mix engine oils 5W40 and 10W 40. the viscosity of these products is different.

Mixing of lubricants with the samethe value of the last digits displaying the temperature regime at which their operation will be as correct as possible. It is better to mix oils if they are from the same brand. If the brands are different, then you can mix only in order to increase the oil level and get to the SRT. All because of the additives that manufacturers use. These components are almost always different, used together, they can conflict with each other and precipitate.

We should note that there are also opposite opinionsmasters-motorists who assert that oils on one basis can be freely interfered with each other, and it will not have any negative effect. Perhaps this is true, but you do not need to take risks without extreme need.

If there is a situation where you need to top up the oil, ideally you should call your dealer and find out which oil is allowed for mixing.

Finally

Now we have finally figured out whether it is possiblemix engine oils. Do not do this if there is another, more conservative solution to the problem. When on the road there was a need to add lubricant, it is better to try to tow the car to the service station, where they can add "native" oil or fully replace it. But if there is no alternative, then pour what is. But get to SRT slowly, without loading the power unit. The main thing is that now you know whether it is possible to mix engine oils.
