Is it possible to mix the car of different viscosity. Motor oil: Is it possible to mix oils? We understand in the composition

Among motorists there are many rumors and opinions on the topic of compatibility of different oils in the engine. Some consider it unacceptable, while others constantly make N do not notice any problems in the work of the power unit. In fact compatibility motor oils - This is a difficult question in which we will try to figure out in detail.

General rules to know

Before dealing, which engine oils can be mixed, we confirm that it is really possible to mix them. This is also proven by the existence of semi-synthetic lubricants, which are a mixture of mineral oil (organic) and a synthetic (artificial chemical).

Of course, despite the strict ban on mixing engine oils different manufacturersSpecialists recommend not to abuse this operation. Mix different fluids only in the most extreme cases when it is not possible to comply with the recommendations.

About the combination of oils with different viscosity

If the motor is filled with mineral lubricant, it is possible to add semi-synthetic and oils produced using hydrocracking technology. In the same way, you can mix mineral water with synthetic liquids generated from polyalphaolefins.

As for the remaining types of synthetic fluids, among which glycolic, polyester and silicone, such oil cannot be poured into mineral. It's all about the synthetic oil formula.

Many are also interested, whether it is possible to pour out various oil into the engine if synthetic or semi-synthetic is flooded, and only mineral water can be added to the topping. It can be done as a last resort, when the oil level dropped sharply, and at hand there is no suitable lubricant.

What are the synthetic lubricants compatible?

Assortment of oils

Many modern manufacturers of synthetic oils establish tolerance according to American API standards and European ACEA. Their requirements suggest that the oil is suitable for mixing with any other lubricants certified by API or ACEA. In this case, the risk of hazardous chemical reactions dangerous for the parts of the engine is excluded, due to which the precipitate may fall out or foaming.

Thus, to the question of whether it is possible to mix oils of different manufacturers if the synthetics motor, the answer is unambiguous: this can be done if the synthetic engine with the API or ACEA certification engine. Details about mixing.

On the mixed oil in the engine you can get to the service center to eliminate breakage or replace oil, taking into account the recommendations of the automaker.

Mixing synthetics with semi-synthetic

Now we will deal with whether it is possible to mix the floor synthetic oils Different manufacturers S. synthetic lubricants? There is such a need if you have sharply fell a lubrication level, and you are far from the service center, but in the trunk there is a canister with semi-synthetic. If the motor is flooded with a clean synthetic oil of 5W40, you can no special problems to pour semi-synthetic 10W40 into it, and at the output it will turn out a completely efficient liquid with a viscosity of about 8W40.

It will be even better if you have a 14W40 semi-synthetic motor, and you pour in it 5W40 synthetics. In this case, you only improve the quality of lubrication fluid and you can safely ride until the next maintenance.

Mixing oils of one brand

Is it possible to mix oils of different viscositybut from one manufacturer? Many specialists and auto mechanics note that it is better to add oil inappropriate to the engine, but from the same manufacturer. Regardless of the above-mentioned standards or, in this statement there is some truth.

Within a certain brand, the compositions of different classes are usually largely similar and contain many common additives. This means that the base in lubricating liquids is the same, so the additives are unlikely to enter into some unwanted chemical reaction. Such oils can be mixed in different proportions. Now you should not have a question if you can add other oil into the engine if you choose the lubricant of the same brand.

Few people think about the fact that even with a standard oil replacement in the motor remains about 5-10 percent old liquid. This is not very much, but in order to avoid conflict, additives is better to fill with a certain brand lubricant. Particularly advisable to adhere to this rule When viscosity changes.

For example, if you have a single grade semi-synthetic motor, and you decide to switch to synthetics, choose the product of the same brand.

Compatibility of lubricants of different manufacturers

We approached the most important issue - is it possible to mix engine oil from different manufacturers? Experts do not recommend this due to different additives. Manufacturers use different chemical additivesA characteristic of the composition. Of course, this does not mean that after mixing, different oils flashes or fall into the sediment.

Each owner of the car sooner or later stands in front of the dilemma - can you mix motor oils of different manufacturers and different viscosity or not? This question is quite natural, since today manufacturers of motor oils (mm) offer quite wide spectrum lubricantswhich differ in their chemical composition by the number of additives and in many other indicators. In addition, oils are manufactured on a mineral, synthetic or semi-synthetic basis.

You can actually mix mm, and even make "mixes" from mineral water and synthetics, most importantly, know the measure and adhere to the recommendations. The fact is that all lubricating fluids There are appropriate compatibility tests with other oils. In this case, such a product is accompanied by the necessary certificates, where it is indicated in the MM presented there are no additives that can conflict with additives of another oil. This in theory, in practice, "unpopular" manufacturers rarely carry out similar checks, so if you plan to mix oils, make sure that you use the product from the proven company. For example, if you are Castrol and Mobil or Shell and LukoL and LUKOIL, which belongs to one class, then such a mixture has a place. That is, if synthetics or semi-synthetic has a similar viscosity and this product is designed for the same engine type, you will not harm the motor.

What oils can be mixed

Many specialists in one voice say that it is possible to interfere with products from different manufacturers, or different classes in an emergency situation. After that, you need to go to the service center as quickly as possible, where you need to rinse the engine and pour new oil. In fact, such "horror stories" are artificially created and in fact are not true.

Everyone knows that motor oils differ in several parameters:

• by base basis (mineral, synthetic, semi-synthetic);
• according to the degree of viscosity (SAE index). Oils are labeled from 0W-60 to 15W-40;
• by its classification (API, ACEA, ILSAC). MM can be for passenger, freight, gasoline, and other types of engines.

Accordingly, if the mixed oils will be answered by the same parameters, then you can mix them.

What will happen if mixed oils on a different basis

If we are talking about the synthetics, they can be mixed with any other product that is suitable for its standards, that is, has tolerance according to API or ACEA. According to these requirements, the manufacturer must provide a product that will absolutely calmly postpone such a neighborhood. In this case there is no danger for parts of the engine. Also in the process of such a mixing will not happen any chemical reactions that will provoke the appearance of the sediment or foaming of the fluid.

If we take the 5W-40 synthetic oil and the semi-synthetic 10W-40, then nothing terrible will also happen. Mixing the two of these liquids, we will get a completely efficient "cocktail" with rates of 6W-40 or 8W-40 (depending on the proportion of old and new oil). But it is best not to top up mm, and wait for the planned replacement and pour petroleum products in equal shares.

If the engine is already filled with "mineral water", then it can be mixed with semi-synthetic oil or with synthetics made on the basis of polyalphaolefins (PJSC). Mixing mineral water with polyester, glycolic and silicone synthetics can not always. In what cases it is permissible to find out only at the manufacturer of your car brand.

The safest method of mixing oils, according to manufacturers

The products of the same brand usually have more common elements, so experts adhere to the opinions that it is better to add little brand to the engine better in the engine than to pour mm with similar characteristics from another firm.

This is explained by the fact that the number of additives in liquids from one manufacturer usually coincides, as well as other elements. From this it follows that, in fact, the basis (even in different material viscosity) will be the same, which completely will exclude the possibility of conflict of additives in the mixing process. It is also worth noting that mm one brand can be safely mixed in any relations.

With the planned transition from the oil of one viscosity to the other, it is also recommended to use a liquid of one manufacturer. The fact is that when replacing lubricant in the engine, about 5-10% of the old product remains, which may be sufficient for the same additive conflict.

In custody

The results of how different oils behave with each other at one time were published in one journal dedicated to auto-subjects. During the experiment and laboratory testing, it was possible to prove that similar in their characteristics of oil different firms enter into chemical reactions, but these changes do not affect the engine performance and its "life expectancy". All recommendations and horror stories associated with the fact that it is possible to pour mm only from one manufacturer, nothing else like a commercial move, so do not be afraid to experiment, most importantly, do it with the mind.

High-quality lubricant is a guarantee of reliable and long-lasting engine. Often car owners boast how often they change oils in the car. But today we will talk not about replacement, but about the topping. If in the first case there are no questions arise (I plited, flooded and drove), then in the second opinion of motorists diverge. Is it possible to mix the synthetics and synthetics of different manufacturers? Some say that you can. Others say it is categorically prohibited. So let's try to figure it out in this matter.

The reasons

There are several reasons for mixing. For example, after a trip to another region, you have dropped the level of oil on the dipstick. Especially often it happens on turbocharged motors with a mileage of more than two hundred thousand. Naturally, in order not to test the engine, it is necessary to resume its level as soon as possible. You move to the nearest store, but the shelves do not turn out to be the oil that you are flooded in the car. Is it possible to mix the synthetics with the synthetics of different manufacturers? We will tell about it a little later. In the meantime, consider another major reason, because of which it has to top up the oil.

This is a malfunction of the cylindrophone group. So, the consumption of lubricating fluid affects the presence of bulwes and other deformations of the cylinder walls, as well as the state mastery rings. The latter may climb on the expiration of a long run. Also, the oil penetrates the chamber due to the ellipsence of cylinders. Yes, no one excluded natural care. But it should not exceed 20 percent of the total replacement time (this is 8-10 thousand kilometers). If you have to simplify the oil often, this is an occasion to think about the health of the cylindrophone group.

Also topping the oil car is required due to poor-quality seals. Often car owners forget to change crankshaft glands (front and rear). The part is kopeck, but to replace it, you need to reverse half of the boost space (especially if it is the rear gland). Look, there is no trace of the drift on the engine and hinged equipment. Perhaps the topping of oil you have to do precisely because of poor-quality seals.

We understand in the composition

To answer the question "Is it possible to mix the synthetics and synthetics of different manufacturers", you need to understand the product. Distinguish three types of lubricants. But regardless of the type, any oil contains a "base" and a set of additives that give it special, individual qualities. This applies to synthetics, mineral water and semi-synthetic. At the same time, each manufacturer uses its own technology and the method of obtaining the basis ("base"), as well as a set of additives.

Thus, even with the same viscosity, these products will differ among themselves. This causes certain difficulties when mixing different oils. As the tests have shown, largely products differ in the set of additives. This does not allow you to mix the synthetics of different manufacturers. Is it possible to do this with mineral oils? The answer will be negative. Yes, the mineral water is more gentle by the engine. But this does not mean that it can be mixed with products from other manufacturers.

Effects

What will happen if you add oil to the engine of another manufacturer? No one will guarantee that the motor will adopt such a "cocktail". Alternatively, due to the mixing of different additives, slag deposition will occur in the engine.

With long-term operation, it can cause a ringing of the rings. Part of the product will fall into the sediment. Additives will no longer provide former characteristics. The composition of the oil film is disturbed, which can lead to climbing oil-conductive channels. All this leads to the overhaul of the engine. Is it possible to mix the synthetics and synthetics from different manufacturers? Experts give a negative answer. Such experiments can turn into terrible consequences.

On viscosity

As you know, any oil has its own classification by SAE and viscosity. When choosing a new product you need special attention Decide viscosity. This parameter depends on the quality of the engine launch in winter and its operation during the summer. Is it possible to mix the synthetics and synthetics of one brand, but with different viscosity? This can be done, but undesirable. Let us give an example. You are in another city, and the emergency oil lamp caught fire. You get the dipstick, and it is practically "dry." But the store did not have oil with the same viscosity of one manufacturer.

Instead of 5W30, you purchased 5W40. What will happen as a result? Is it possible to mix 5W30 synthetics with 5W40? When mixing, you will change viscosity characteristics. So, the liquid will receive averaged parameter (5W35). What will change in the future after mixing? Among explicit signs It is worth noting the minimum engine start temperature. Now it will be -35 degrees Celsius. But how to behave the additives in this case, no one can predict. If this is a product from one manufacturer, then you will not apply significant harm. But with mixing different marks Oils are worth waiting for trouble.

Mix with minimal risks

So what to do if the level fell and in stores did not turn out to be the same oil? You need to know several rules:

• Try to choose products, as similar to the characteristics with your oil. So you exclude risks.
• Is it possible to mix the synthetics and synthetics of different manufacturers? Do not buy lubricant from other firms. Each company uses his set of additives, which is added to basic oil. Because of this, the characteristics of the film can vary significantly.
• Adjust minimal viscosity differences. You can not pour into the engine, where 0W20 was previously used, even if the manufacturer had the same.
• Do not change the type of oil. If you are filled with synthetic, in no case mix it with mineral and even with a semi-synthetic (let and viscosity will be the same). It will significantly harm your engine.

What to do on arrival?

So you returned to your city and put a car in the garage. What to do next? Experts recommend to completely merge such a "cocktail" and change it to a new, homogeneous oil. The intermediate step will be the use of washing oil.

The exception is cases with the addition of synthetics of one manufacturer, but with minimally distinguishable viscosity (as we noted earlier, it is 5W30 and 5W40). In the event that the volume of the oiled oil is small, it is not necessary to produce full replacement. You can ride with such a "cocktail" and below. We will tell about this nuance below.

Harmless volume

As you know, completely merge the entire volume of oil from the engine will not work. How not to twist, but 500-800 milliliters of the liquid still remain in the system. What is it all? If you fastened some oil, you do not need to repeat extraordinary replacement. This is an absolutely safe amount that will not harm your engine. But remember that this is possible only when mixing products from one manufacturer. Also, the composition should not be different in viscosity characteristics.

Going to the long road, capture with you a small (at least liter) eggmarket oil. Perhaps she will not be useful for you. But if necessary, you will save a mass of time and effort spent on the search for oil of the desired viscosity and the manufacturer.

In addition, at refueling, the cost of products is much higher. It is also not superfluous to be a small canister with antifreeze and other workers by the way, too, can not be mixed with different classes and manufacturers. But this is the topic for another article.

Correctly go to another type of oil

Over time, car owners have a desire to change the mineral water on the synthetics or vice versa. But it is necessary to do it correctly, because the oil part will still remain in the engine. Is it possible to mix the synthetics with mineralka? Absolutely not. Therefore, when switching to another type of fluid, use wash oil. Give me to work the engine on it for 5-10 minutes, you can not be afraid for the inconsistency of additives and the "base".

After the "washing" is fused, it is safe to pour oil of another type, without fear of consequences. Also do not forget to change and oil filter. It also accumulates a decent liquid volume (and dirt no less than ten thousand kilometers of run).

Conclusion

So, we found out one and different manufacturers in the car engine. As you can see, it is not always safe to top up. Remember that different companies are used different methods And in particular additives. And how they will behave when mixing with the other liquid, it is worth only to guess.

Spores of car owners about the possibility of mixing engine oil in the engine will not subside over for many years. Someone assures that any harm for engines in this case does not exist, while other car owners or motor repair professionals claim that it is prohibited to mix lubricant. Let's talk more about whether you can mix different in the engine automotive oils.

The car's engine is a complex node in its design, within which numerous moving elements are located, during operation, the heating moving nodes are subjected to increased wear. To protect such moving nodes, preventing premature wear and for cooling the motor and are used special automotive oils. Currently, it is customary to distinguish three types such a car motor lubricant:

Mineral oil is a natural product that is obtained by appropriate oil refining. The cost of such mineral oil is at an affordable level, but in its operational characteristics it is significantly inferior to synthetic samples.

Synthetic oil It is manufactured by special technology from a variety of chemical components. Such a lubricant is distinguished by resistance to temperature drops, does not oxidize and last time saves its operational characteristics. The only drawback of such a synthetic oil is its high cost.

Semi-synthetic - This is an intermediate grease that contains both synthetic and mineral components. This semi-synthetic exceeds inexpensive mineral oils in separate parameters, but it is somewhat inferior to clean synthetic.

High-quality oil will provide the necessary engine protection, warning it premature wear. Also, the lubricant is responsible for cooling internal moving nodes and parts, the temperature of which during the engine operation can significantly increase. Today, high-quality technical fluids are capable of preserving their operational characteristics for a long time. And yet, after 8-10 thousand kilometers, the oil loses its characteristics, which forces the relevant service work, within which the lubricant changes and filter elements. Performing such a service on a regular basis, it will be possible to warn the appearance of the engine breakdown, the elimination of which will cost the car owner in the round sum.

In the recommendations of the automakers and oil producers themselves, you can find contradictory recommendations for this mixing lubrication. It should be said that there are certain standards of oils that characterize the chemical and physical properties of lubricant. In the event that such standards differ significantly, for example, as in synthetics and mineral compositions, it is not recommended to mix such a lubricant. But it is possible to mix in the engine, for example, semi-synthetic or synthetics from various manufacturers and with different viscosity indicators - there is no unambiguous answer.

Today, such oil manufacturers use various chemical formulas, which allows them to produce a high-quality product that provides full protection of the engine during its operation. At the same time, even oils that relate to the same category and which have the same viscosity parameters, can use various chemical components that react with each other, and neutralizing or deteriorating their characteristics. Accordingly, with mixtures inside the engine, significant deterioration may be marked performance characteristics Lubricants, as a result, premature wear appears and the engine will soon require serious repairs.

If in some cases mixing semi-synthetic and synthetic oil is allowed, then placing mineral oil into the engine, where synthetic or semi-synthetic is strictly forbidden. Different chemical composition of such lubricants will lead to the fact that the oil will simply come. As a result, the oil channels will be slaughtered, and the pistons are completely encouraged. Such an engine after mixing the oil will require a serious overhaul.

In some cases, with any breakdowns on the road, the car owner faces a dilemma if it is possible to fill another oil into the engine, mixing with the existing lubricant, or should be swirling the car engine and carry the car to the service on the tow truck. It should be said that safe short-term operation of the engine is allowed to mixed oil. At the same time, it is possible to mix only the lubrication of the same category, that is, semi-synthetic mix with semi-synthetic, synthetic oil with synthetic and similar mineral compositions. Remember that this is only a temporary measure to take home or to the car workshop, where the engine will be repaired and the subsequent replacement of oil on a new quality lubricant.

IN emergency situations A decade percent top of the engine similar in terms of oil characteristics is allowed, which will not lead to changes to its characteristics. Remember that even with the usual replacement of oil in the engine, it is impossible to completely drain the lubricant. In the motor, 10-15 percent of lubrication can remain, and, pouring new oil, we, willy-nilly, mix such technical fluids. That is why, at the emergency case, 10% of oil, even with slightly different characteristics, will not result in any serious problems of the engine.

If you still for any reason tighten the oil into the engine, then remember that it is not recommended to mix oil from different manufacturers and with different characteristics. The chemical composition in such a lubricant may differ significantly, which will lead to undesirable chemical reactions and losses technical characteristics And oil inside the motor. As a result, elevated wear will appear, and the engine will soon require a complex expensive repair.

conclusions

Mix oil from different manufacturers and with various characteristics In the car engine still should not. This can lead to serious problems in the operation of the motor, as a result, will need expensive overhaul. That is why we can recommend you to acquire engine oil with a small margin and a canister for several liters to constantly carry with you, which will allow you to add high-quality oil to the engine in the engine, avoiding any difficulties with the operation of the power unit.

The trading network suggests big choice Motor oils from various world manufacturers. There is a specific rule that is suitable for creating ideal conditions: in the engine crankcase you need to pour engine oil in accordance with the recommendations of the manufacturer's manufacturer's manufacturer.

Many drivers are wondering if motor oils can be mixed and what will happen to engine performance internal combustion wherein. Theoretically, this question can be answered in the affirmative, but with certain reservations. Experienced motorists more carefully apply to this issue. They advise the use of mixtures only in cases of extreme necessity.

Mixing synthetic, semi-synthetic and mineral oils

There are no official prohibitions or permits for mixing motor lubricants belonging to various groups and brands. On this account, there are many recommendations or regulations. However, this does not mean that they can be mixed without restrictions.

The main risk for internal combustion engines is not a mixture of the basic bases, but in the chemical interaction between elements of additives in the oils of various groups.

There are cases (a sharp decrease in the lubrication level), when there is no possibility to use proper oilTo get to the nearest service station service.

Mineral lubricating fluid can be mixed with marks belonging to semi-synthetic or synthetic groups, which are manufactured by hydrocracking or based on PJSC (polyalphaolefins). Other synthetic materials (glycolic, polyester, silicone) are not compatible with mineral oil.

Only the official representative of the autobrade can, with confidence, to recommend, which substances can or cannot be mixed for this car.

Many modern synthetic oils released under famous brands, have admission to ASA standards (for producers of Europe) and ARI (USA). In accordance with their requirements, Mixing Motor Oils is provided different marksCertified under the indicated standards.

Such mixtures do not form hazardous chemical reactions of gasoline and diesel power units. At the same time there is no foaming and harmful precipitates do not fall out.

However, experienced experts and auto mechanics warned by car owners from permanent operation vehicle With a bold cocktail. Mixing lubricants Different groups and manufacturers within the standards of ASEA and ARIBU only for temporary replenishing the missing amount of engine oil in the engine. The resulting mixture is not intended for long-term use in the further operation of the machine.

This suggests that in case of emergency situations, you can add a certified oil of any other brand to preferably worth the service center without increasing the load on the internal combustion engine. Next, the following are:

1. The motor malfunctions are eliminated.
2. Fully replaces the oil on the brand corresponding to the recommended one.

Simultaneously with the complete replacement of lubricant, it is necessary to install a new filter element ( oil filter). The interval between the following oil replacement activities is reduced several times (in two or three times), because In the power unit crankcase, an old oil remains, which is impossible to completely drain (almost 10% of the volume).

How is the semi-synthetic and synthetics mix? If there is a need for such mixing, it is best to add a better lubricant. For example, a synthetic engine oil 5W 40 can always be added to the semi-centtetic machine 10W 40.

Motor oil compatibility from one manufacturer

Lubricating fluids, issued under one brand, have similar characteristics, as based on common elements. According to experienced experts, it is possible to mix different viscosity oils if they are released by one manufacturer. This is true, because lubricating products of one brand, despite different levels of viscosity, consist of similar chemical elements.

Additives from one manufacturer are also based on similar components and do not have significant differences from each other. The conflict of additives will not happen when they are mixed, any proportion is allowed.

Motor oils of different manufacturers are competent much more difficult than representatives of one brand. At the same time, the risks of potential conflicts between different additives increase significantly.

If you need to go to another viscosity, it is recommended to remain within the same company. When performing complete service replacement of machine oil in force aggregate There remains some of the old substance (about 5 - 10%).

To secure car Motor From possible trouble arising from conflict additives, it is better to use lubricating liquids of one company.

What will happen if mixed substances of various brands? It should be remembered that this is a rather risky event. Each corporation protects its products stored patents, especially unique additives. Perhaps nothing terrible will happen. But there is always the likelihood of foaming the mixture and falling into a precipitate. If different substances can occur, an incorrect chemical reaction to the result of the inevitable interaction of their components may occur.

Conclusion: oils can be mixed, but at the same time adhere to their belonging to one brand.

What beneficial features There were no substances, a mixed oil cocktail will destroy a part of additives from one and the other sides.

When mixing chemical flushing solutions and various additives also apply frames and brand restrictions.

As combined lubricants with different viscosity

As an illustration, it is proposed to consider this example. The combination of oil 5W-30 with 5W-40 leads to a decrease in viscosity coefficient high temperatures Engine. Different level viscosity averaged its value that is insignificantly for end result. The viscosity of the mixture, of course, will change, but cold Engine It will still be launched without problems even with minus 35 ° C.

The manufacturers of lubricants are silent about the prohibitions for mixing motor oils of various groups and brands. However, the recommendations are about the need to use oils, flushing fluids and specialized additives only from one manufacturer.

Many car owners do not trust such allegations. They are confident that these are just a banal attempts of companies to put consumers to use their products.

When choosing technical fluidsIn particular lubricants, it is necessary to comply with the maximum responsibility. This product should be purchased only in branded outlets from proven suppliers and sellers. High quality engine oil, selected in accordance with the automaker's recommendations, will ensure uninterrupted operation of the internal combustion engine for a long time.
