Is it possible to mix alone viscosity oils. How safe is in the car engine mix different oils? The safest method of mixing oils, according to manufacturers

It is worth starting with the fact that the topic of this article is relevant for almost every motorist. The question regarding the selection and subsequent compatibility of different engine oils is actively discussed both among beginner drivers and in the circle of motorists with experience and professional auto mechanics. The main problem is that the modern market offers a huge amount of lubricants, additives and additives. The number of their manufacturers exceeds several dozen, and oils themselves have a number of differences in classes, groups and branded packages of chemical components in their composition.

Perfect conditions

Each motorist knows that the health of the motor in the car is directly connected with high-quality engine oil and its regular replacement. Engine oil is recommended to change every 7-10 thousand kilometers traveled.

The recently realized car has an oil in its engine, which was flooded in force aggregate At the car factory. Further exploitation, subject to the preservation of warranty obligations, implies the passage of subsequent planned technical inspections exclusively at the dealer at authorized official stations. This means that it will be used recommended. motor oilwhich is implemented by the dealer for subsequent replacements.

Such oil is naturally the products relating to one recommended group recommended for a particular motor. Most often on the dealership, the oil will also be a product of one brand and will correspond to all tolerances, requirements and prescriptions. It will be changed without flushing, but if necessary, such oil in the engine can be without unnecessary concerns. This scheme is optimal for the motor, but in practice, conditions may change.

For what reasons Motor oil is mixed

Now let's talk about the main reasons for mixing oils and potential problems after that. The problem lies in the fact that even a thorough removal of spent oil from a drain and / or pumping allows the remainder of the test in the engine with a volume of about 0.5 liters or more. It turns out that part of the old oil is mixed with fresh lubrication.

It is the opinion that oils from different manufacturers may not have full compatibility. Many fear that the use of oils of various groups and classes for this reason is not a 100% security guarantee for the motor. We will try to answer, whether it really is.

Replacing one group of oils to another

Not all owners prefer to serve their cars on official dealerships, where during that fuel the same and recommended motor oil. The issue of compatibility of oils occurs when the owner of the car makes the decision to pour another oil.

Forced need to attach oil

In the process of operation of the car, an urgent need to urgently attach the engine oil with a sharp drop in its engine.

Practice shows that most drivers at such moments do not have in the car reserves of such an oil, which was already flooded in the engine. In the nearest trading network or the gas station is not always possible to purchase necessary oil For topping. Since the emergency situation, the car owners in emergency case Take the oil of any manufacturer.

Flushing and additives

Among motorists, the practice of using all sorts of additives in the oil was widespread. Such additives are designed to strengthen the efficiency of work and serve to improve useful detergents and protective properties.

The regular procedure for washing the engine with all sorts of flushing compositions before the next service replacement of oil is potentially harmful due to the fact that the mixture of oil and the additive from the motor is not possible.

Potential danger

Now let's imagine that in the fresh oil of one manufacturer, the owner poured an additive and drove about 10,000 km on such a mixture. Next, the washing composition was used again before the next replacement of the engine for cleaning the engine from the inside. The last step was the next oil refueling with oil, but already from another manufacturer.

Once again, note that from the engine it is impossible to completely remove the resulting old "cocktail". It turns out that in the engine there is about half of the liter of the residues of a mixture of used earlier oil, additives and washing. Such residues are mixed with new oil. If, after replacing the oil, add an additive, then an additional chemistry portion will be in the fresh oil.

It is natural that many people have a question about the compatibility of all components between each other and their final exposure to the properties of the base engine oil. Let's deal with this issue.

Some information: Motor oils

We will immediately disclaim that we will not stop in detail the description of the unique properties of certain types of engine oil. Consider only the main types and composition. Motor oils are:

• mineral;
• semi-synthetic;
• hydrocracking;
• synthetic;

The basis for oils is the basic part in which the manufacturer adds packets of various chemical additives.

Additives and determine ultimately the main characteristics of the engine oil. Additive packages are a unique patented development of manufacturers, which acts as the main trump card of a brand in the fuel market. Manufacturers compete with each other and are in no hurry to disclose all the components of their compositions.

Mineral oil is distinguished by a special mineral base and a package of additives to improve the qualities and properties of such an oil. Synthetic oils are a product using a synthetic base and additives that are calculated on the interaction with only synthetics. If speak about semi-synthetic oils, then they are obtained by mixing the mineral and synthetic bases in certain proportions.

The mansion on this list is hydrocracking. These oils occupy a place between semi-synthetic and fully synthetic products. This oil Manufacturers are obtained at the initial stage of the natural mineral base, but it then passes the process of special chemical processing on unique technology.

Is it allowed to mix oils of different groups?

Each of the above types of engine oils differs from each other by the basic basis. For each basis, a unique package of additives is applied. Additives are added to all oils. Mineral, semi-synthetic, hydrocracking and synthetic engine oil contains additives to achieve those physicochemical properties that are required from one or other type of oil.

It is worth adding separately that such additive packages differ in their chemical composition. The scope of their application is limited to taking into account the harsh requirements in relation to a particular group of engine oils. The result becomes that each manufacturer has several types of mineral, synthetic and other oils among the products presented in the product market. These oils receive a different basic base and the corresponding additive packages.

The huge list of world manufacturers of oils for engines today offers the richest range of products on the shelves. For this reason, the owners of gasoline and diesel cars Assist about whether such oils can be mixed with each other.

Below we collected the material that is based on a number of independent research and recommendations of car manufacturers, included comments by manufacturers of motor oils, etc. The reviews of experienced car mechanics and car owners themselves were taken into account. We will talk about those details that need to be considered before you decide to mix motor oils of different manufacturers.

Officially mix motor oils is not prohibited

Indeed, official prohibitions for mixing various groups of oils you will not meet anywhere. There are only prescriptions and recommendations.

This does not mean that oils can be freely mixed, but it is permissible when itemies occurs. The basic base itself may not be problematic when mixing oils, but a chemical reaction between additives from the other group of engine oils.

Turns out that mineral oil, synthetic oil Based on polyalphaolefins (PJSC), as well as hydrocracking oil in extreme cases can be mixed. This conclusion comes experts, referring to the existence of a separate group of semi-synthetic engine oils, which themselves are already a similar mixture. Synthetic polyester oil, glycolic, silicone and other oils, the base of which differs from PJSC, mixing with mineral water and semi-synthetic is necessary with caution.

From manufacturers of motor oils, you will also not hear about forbids. But the recommendations and prescriptions are present. The main one of these recommendations is the use of such motor oils, additives and flushing, which are products of one manufacturer and / or brand. Interestingly, some car owners put in question, explaining this prescription by the manufacturer's banal attempt to tie consumers only to their products.

It is worth it to add that there are several clearly decorated API standards, which are characteristic of the USA and ACEA standards for Europe. These standards make a prerequisite for synthetic engine oil of one brand to be able to complete mixing with any other engine oil or product that has passed the certification process and meets the specified standards. It is noted that when mixing should not occur any potentially dangerous for automotive gasoline or diesel engine Chemical reactions. The probability of precipitation is completely excluded, the effect of foaming the resulting mixture, etc.

Auto mechanics and experts separately add that such standards are not at all provide the owner of the auto able to fully exploit vehicle With mixed oil in the engine, but they make it possible to immediately add any oil within the framework of the standards if the level of engine oil in the engine has sharply fell.

This means that when an emergency emergency occurs to add oil and after reaching the place of repair without increased loads on the motor is quite acceptable. In this case, the further operation of the car on the resulting oil mixture is not meant. The following actions include a drainage of mixed oil from the motor. Then you need to immediately replace the lubricant on the engine oil recommended by the manufacturer.

The mandatory replacement is also subject to filter oil element (oil filter). Remember that after that, the interservice interval until the next replacement of the engine oil will additionally need to be reduced in two, and even better three times.

Mixing oil and viscosity indicator

Mixing engine oils of one group, but at the same time different viscosity, it is permissible. The only nuance is that the so-called high-temperature viscosity coefficient can suffer. For example, in synthetic oil with a viscosity indicator at the mark of 5W40, the semi-synthetic agent is 10W40. The total viscosity of the mixture obtained will be about 6W40, 8W40 or higher. The final viscosity will depend on the number of less viscous oil added.

Most correctly mix the oils of one manufacturer

On this question we will help to answer the analysis of the various compositions of the products of certain manufacturers. The fact is that even oils from different groups, but one brand, will be in its composition to have more general concerning basic chemical elements in the additives. This statement is confirmed by comparing one oil with similar products of other brands.

This recommendation allows you to minimize the risk of a possible conflict of oil components. Auto mechanics, car owners and even some dealers insist on the fact that in emergency cases it is better to mix motor oils of one manufacturer than similar in the group and viscosity of oil, but different brands.

The practice of using the products of one manufacturer Many car owners are used and when changing the oil group to another. At the same time, the use of additives and chemical flushes is also limited to these frames.

Finally, I would like to add that it is necessary to approach the choice of lubricants and other technical fluids with maximum responsibility. Purchase similar goods only in proven and official sales points. This rule will allow your engine to always stay well and go through hundreds of thousands of kilometers without repair!

Whether to mix motor oils 4.75 /5 (95.00%) 4 Voice (s)

Is it possible to mix motor oils of different manufacturersOn this occasion a lot of disputes and opinions. Some think that all motor oils are the same. Therefore, poured into the engine what is cheaper in the store. There is another myth that there is a distinguished viscosity, various chemical additives - already suggest that motor oils are all different, and they are categorically impossible to mix them. Let's figure it out in this matter.

Afraid, what is deceived in the car service? Click on any of the messengers below to learn 5 simple ways how to avoid cheating 👇

Mix motor oils of different manufacturers usually when the car owner has a desire go to the lubricating liquid of another brandwhich differs accordingly by viscosity and type.

There are also situations where the car owner is forced to add other engine oil. The reason to become the drop in the oil level in the engine, and the suitable at hand did not turn out, or there is no on sale. And go to such a step, topping the engine oil of another brand.

Modern engine oils can be mixed with each other without any consequences. Moreover, any, semi-synthetic with mineral, synthetic with semi-synthetic, diesel with gasoline, 5W30 from 15W40. Prove it is simple enough.

Within one concern, the base for all oils is the sameYes, and additives almost the same. Therefore, such liquids are allowed, and in different proportions.

However, almost no one thinks about whether the most common oil replacement and oil filter, in the engine remains around 5-10% Exhaust liquid.

Any product that is produced in the world complies with standards, quality standards. Motor oil is no exception.

The main criterion for compliance with the US standard API., European Acea. It consists in compatibility and mixing oils.

If the manufacturer fails to provide mixability, it will not receive compliance with API and ACEA, with all the ensuing consequences. Which reach up to the ban on selling such oils in the American and European markets. It is for this that additives that prevent foaming are applied.

You can mix, for example, Synthetics 5W40 with semi-synthetic 10W40, and get oil with a viscosity of 6W40 or 8W40, depending on the ratios of mixed oils.

Thus, if you want to change the viscosity of the engine oil, it is better to use the liquid of one brand. For this reason, additives and various chemical components within the concern will not differ. Therefore, motor oils of one concern are best in contact.

Inside the brand, any oils are mixed in any proportions.

The reasons:

• The same oil base.
• Visidial additives are the same.
• Packages of additives, in the bulk of the same.

Of course, the motor oils will differ, but it is definitely not to conflict. It's no secret to anyone, there are plants manufacturers producing motor oils under different brands. With the same oil, and the same additives. So the concern earns much more money.

The quality of these oils will be identical. All of them will have similar properties. Therefore, no fallouts in precipitate, folding, foaming will not be. But the price at the same time will differ significantly. And here you already choose, pay for the brand and quality, or for quality.

Motor oils of different manufacturers mix permissible. However, some specialists, and the manufacturers are not particularly recommended. Argumenting by the fact that various brands Enjoy a variety of chemical. Additives and additives that may differ in content. Of course, this does not mean that the liquid immediately foam and falls into the sediment.

But it is best to do that when you plan to ride not long, or in order to get to the right one hundred, in order to avoid negative consequences.

Therefore, many motorists pour into those oils that are recommended by car radio or a hundred. After all, if the motor oils of different manufacturers can make incorrectly, can lead to untiless consequenceswhich happen extremely rarely. However, it is not necessary to abuse such a decision.

Mixing is allowed, but the question is whether it is necessary. The most ideal version of the engine oil is replaced, it is to choose one oil, one filter and replacing yourself, or on the same service station. Thus, you can minimize the risks of the bay of low-quality oil and the installation of a bad oil filter.

Mix engine oil only in extreme cases.

Consider the situation. A light bulb on the track caught fire. but suitable oil With you, it was not. On the nearest service station, at the gas station, there is no such oil in the auto shop.

If the car engine requires special engine oils. In this case, look at the tolerances. Take any suitable tolerance and plot as much as you need until next.

If the car does not require special oils. Then take the software you need viscosity, if there is no, then fill the oil of higher quality.

• In the mineral 15W40 pour semi-synthetic 15W40, or the semi-synthetic 10W40.
• In grasintetic, 10W40 pour the synthetic 5W40.
• In the synthetics, fill 5W40 pour the synthetic 5W30, etc.

If the engine oil is not above your quality, then pour what is happening, but in such a hundred right. This also applies to those cases where the seller and engine oil causes you suspicion. Anti-fake engine oil API, ACEA is useless.

Now we generalize, by what parameters you can mix:

1. When mixed, be sure to see the tolerances - they must coincide (compatible).
2. Oil class must match. Do not leute B. a car Oil intended for trucks.
3. It is recommended to mix the oil of the same viscosity.
4. It is recommended to mix oils related to one concern.
5. Be sure to increase the quality of the oil. To the mineral to add semi-synthetic, in semi-synthetic - synthetics.

Not permissible:

1. Reduce the quality of the oil. Do not leut into synthetic semi-synthetic.
2. Do not mix mineral oil with synthetic.
3. Do not mix in proportions 50 to 50, Best topping in MAK 15%.

Finally…

Now you know that mix motor oils of different manufacturers permissible. However, tighten the liquid of another brand only in the most extreme, emergency cases. Use only high-quality and original engine oils, it will definitely not lead to good.

The question of whether you can mix motor oils, worries many motorists - both beginners and experienced. On this occasion there are hot spores, and there is no one-minded opinion. Often there are situations when you need to top up the oil, but liquid remains from another manufacturer in the car. Here the dilemma gets up - you can do it or not.

The problem also occurs when moving to oil of another manufacturer and other viscosity. Even if you completely drain the lubricant, then use the residual suction device and rinse after that the engine, there will still be about 0.5 liters of old oil composition.

All manufacturers argue that Mixing Motor Oils is unacceptable. Their motivation is understandable - after all, everyone is interested in enjoying only its product, and for a long time. Automakers also adhere to this opinion. They can also be understood - not all motorists are well versed in lubricants. They can allow mixing oils on a different basis or viscosity - for example, mineral water with synthetics. Such a "cocktail" can really affect the engine unpredictably.

At the same time, many car owners worries little, which oil works in the engine. They believe that its normal level is everything you need a motor. They do not care the manufacturer, the composition of the basis or viscosity. Let's try to figure out how to do what kind of compounds can be interfered, and which are not.

Composition and classification of oils

Motor oil, depending on the main composition, is divided into 4 varieties: mineral, semi-synthetic, hydrocracking and synthetic. All of them have various additives, different viscosity indicators, according to the international SAE classifier. The work of each engine oil consists in creating a thin film between the inhibited surfaces of parts in the engine to minimize the friction between them. In addition, the lubricating composition still performs cooling functions. Shears the main engine nodes, removing the net, slags, lacquer deposits, as well as other side products of combustion of fuel.

The foundation

Each oil substance lubricating the parts of the motor consists of two main components - the bases, or base composition, as well as the package of additives that give oil its main qualities, reinforcing and improving the action of the baseline.

Depending on the base, each of the oils has its own characteristics and properties. Mineral oil is characterized by:

Synthetic compositions are best suited for those qualities that motor oil should have. Their advantages:

• Viscosity varies little in a wide range of temperatures - from negative to high;
• low level evaporation and good fluidity;
• High resistance to oxidation;
• Requires fewer additives.

The following features are expressed in the semi-synthetics:

• about low cost, only mineral compositions are cheaper;
• applies to any type of engines internal combustion;
• prevents education, on details, lime taxes;
• It has a small evaporation.

Viscosity

All types of oils from different manufacturers are characterized by viscosity. According to the most common classifier of viscosity - SAE - oils are divided into summer, winter and all-season. According to the standard, there are 6 winter and 6 summer oils. Since in our climatic belts, the temperature variation during the year is quite large, then only all-season oils are used. For example, in the designation of 10W-40, the first combination of 10W is a low-temperature viscosity and determines, to which minimum temperature, the lubricant will maintain its turnover.

The second digit, after W (40) determines which viscosity of the oil composition at the operating temperatures of the engine. It is measured at 100 and 150 ° C, although there are places in the motor where this temperature is much higher. For example, in a cylinder-piston group. If you take, for example, lubricants 0W30, 5W30 and 10W-40, then the following picture is obtained:

Lubricants such as 0W30 and 5W30 are used in motors with a slight mileage when the gaps between the details are small and a good fluidity is required. In the power units with mileage of more than 100 thousand kilometers, it is recommended to switch to a large viscosity - 40.

Combination of oils of different types

Practice shows that in extreme cases, mineral water can be interfered with semi-synthetic and hydrocracking. Mixing oils on a mineral and synthetic basis is also allowed, but under one condition. Synthetic should be based on PJSC (polyalphaolefins). There are both opposite cases - when the level of synthetic or semi-synthetic lubricant falls. Then, in case of extreme need, you can add mineral water in small quantities.

Another option is a combination of oils based on the same composition. For example, mineral with mineral, synthetics on PAO with the same. Such a "cocktail" will work, but it is risky. Well, if the viscosity of both components will be the same.

Mixing synthetics

Mixing synthetic oil compositions from different manufacturers is allowed if their characteristics coincide on the American standard API or european Acea. Especially strictly to this must be taken if the engine is forced, with turbocharging. Any lubricant is impossible to pour - only those that correspond to the levels for such motors, according to the above standards.

In this case, such negative effects like foaming and falling out of the precipitate should not occur. But for a long time to drive on such a "cocktail" is not recommended. Not only in this, but in all other cases of mixing lubricants, you need to merge them - the sooner, the better. Then rinse the engine and pour the lubricant that must match it.

Semi-synthetic and synthetics

Suppose you have a 5W-40 lubricant on a synthetic basis and urgently need to add, since the level fell. And in the presence of only semi-synthetic 10W-40, then you can add it. In this case, the total viscosity will change. It will be slightly less than 10W-40 by low temperature component. But another option seems to be much better - when the 14W-40 half-centtech will have to add a better synthetic product.

Oil with different viscosity

Again, a similar situation for an example - you need to urgently add lubricant, but in the store instead of 10W-40 there was an oil liquid of the same manufacturer with the same labeling, but another viscosity - 10W-30. Well, you can bother to add it. Only in this case, high-temperature viscosity will be slightly smaller, between 30 and 40. That is, the oil fluid will become a bit more fluid in the engine running.

But additive packages will certainly be the same and basic compositions - too. In this case, you can even add a rather large volume of engine fluid. At low temperatures, the motor will also be well run to one temperature value -25 ° C, since low-temperature viscosity indicators of both oils are the same.

Lubricants from various manufacturers

Mix the oil compositions from different manufacturers - the risks of everything. No one guarantees that they will be compatible, especially if manufactured on the basis of various basic compositions. For example, synthetics may be based on polyalphaolefins (PJSC) and on a completely different NC synthetics (the same hydrocracking). In addition, the composition of the additive will certainly differ. Although in most cases they do not conflict with each other. It is simply possible to generally reduce the useful qualities of such a "cocktail", which will negatively affect the operation of the power unit.

Lubricants from one brand

Such a mixing option is most successful. The fact is that oil fluids, produced in the same company, are very similar to each other. Especially if it comes to the same basic basis. Experts converge in the opinion that mixing compositions with different viscosity is painless for the engine. A little will change the fluidity in one direction or another, but there will be no significant changes to lubricating, detergents and other functions.

If oil liquids have one base - 100% chance that they have identical additive packages. It may be a bit in different proportions added viscous. Such mixesters often occur when motorists go from one level of viscosity to another, while pouring the oil of the same brand. In the motor still remains the old lubricant, and it is mixed with a newly bold. By the way, if with this transition uses the lubricant of the same manufacturer, it is not worthwheeling. From this there will be more harm than good.

Conclusion

As can be seen from the above, nothing terrible is to briefly mix the oils on different base compositions and even from different manufacturers, no. The most important thing is not to go long on such a "cocktail". If different compositions flooded from different manufacturers - it's best to get to the first store and buy that lubricant that suits your power unit. Then change motor fluid On the first time, pre-flushing the motor. In this case, it will not be harm to your engine.

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 it is possible to mix various car oils in the engine.

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 manufactured by A. 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 its 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 qualitative technical fluids Capable for a long time retain their operational characteristics. 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 on mixed oil is allowed. 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 the engine 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 pay oil to the engine for any reason, remember that mixing the oil from different manufacturers and with different characteristics Not recommended. 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 the oil from various manufacturers and with different characteristics in the car engine should not be. 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.

Many car owners at least once fell into a situation where the oil level in the engine suddenly fell below the permissible minimum, it is necessary to go urgently, and the same oil, which is flooded in the engine, there is no, but there is some other one. A natural question arises: can the engine oils can be mixed, and how threatens?

This dispute is very long ago, and many opinions on it. Thus, manufacturers of lubricants in a categorical form state that it is possible to add to the engine exclusively then the oil that is already flooded into the engine, and any speech mixes can be. You can understand this point of view, because each of them is interested in the car owner by choosing one brand of oil, it remained faithful to her for a long time.

In addition, in this way, manufacturers seek to protect themselves from possible complaints from car owners due to the occurrence of engine faults caused by an inappropriate oil tank. The automakers are followed by the same opinion.

Among some car owners, a completely opposite opinion is common, they say, "lubricant - she and in Africa lubricant." The most important thing for them is that the level remains in the norm, and which "spreading" is covered in the engine, they care little.

Truth, as usual, is somewhere in the middle. Motor oils can be mixed, but it is allowed only as a last resort, when it does not seem to continue in a different way. The purpose of this article is not a call to pour into the engine all that fell at hand.

Short Likbez

Before finding out whether it is possible to mix oils, and how it will reflect on the state of the car, it should be understood that they represent.

So, the engine oil is a mixture of the base and various additives. Basic properties are determined by the basis that can be mineral, synthetic or mixed in a ratio of 70/30 percent, of which the synthetic component accounts for a smaller part. The same foundations of motor oils of different manufacturers differ little from each other, i.e., all synthetic, whether Motul, Honda or Castrol, have the same basic properties.

• A set of operational characteristics of motor oils is determined by additives.
• Each manufacturer itself determines their composition and quantity, seeking to obtain certain product quality.
• The chemical composition of additives for different oil bases is completely different, for example, in "mineral water" additives are added, providing a stable viscosity, which does not require "synthetics".
• When mixing various oils, additives can join chemical reactionthat will negatively affect the properties of lubricant material.

Arguments against mixing: Is everything scary

From in order to bring the lubrication level to the norm by hand, the car owners stop several arguments. Below will be considered as far as they are justified.

1. Unacceptable mixing of varnosate oils, because This will lead to a motor outlet.
2. It is unacceptable to mix products from different manufacturers, because Additives contained in them will react with each other with the most disastrous consequences.
3. It is unacceptable mixing of different oils, the reason is the same as in paragraph 2.

Mixing oils of different viscosity

Low branched oils

Modern engine oil in many engines is not only lubricant material, but also hydraulic fluid. If in certain places the required pressure will not be created, the operation of some systems of the power unit will be impossible, for example, VTEC gas distribution phases in Honda motors.

Thus, the requirements are presented not only to the thickness of the film, but also to the fluidity. For this reason, many automakers, including the already mentioned Honda, recommend pouring oils with increased fluidity, 0W20 viscosity.

Another requirement is presented to modern engine oils: high alkaline activity. This is necessary to achieve good detergents so that the lubricant is able to wash the dirt and wear products from thin places (the same VTEC system).

Of course, if you constantly "feed" the engine with oil is not enough high quality or to change it, problems are guaranteed. However, fresh oil, even with a higher viscosity, the first time will be able to ensure normal operation of the engine. The main thing is not more than 2000 km, replace this mixture.

If we talk about mixing different viscosity as a whole, then, again, the damage for the engine does not cause this procedure, especially if we are talking about the products of one manufacturer. The resulting viscosity value will be some meaning, depending on the proportions. For example, when mixing oils 0W30 and 5W40, it may end up 2W34 or 4W38, depending on how much oil was added.

Mixing oils of different manufacturers

Mix the products of different brands is also quite acceptable. Of course, if you do not take into account completely low-quality oils. Despite the fact that all manufacturers add different additives and in different proportions, with their mixing disaster will not be. Yes, they may well react with each other, but such results like foaming of lubricant or precipitation will not be.

In the worst case, the mixture will lose the branded positive properties of oils, but will remain quite suitable for the car to drive up to 2000 km. Of course, it is necessary to merge it from the motor, if possible faster. If, after the production of the production of another brand, the power unit failed, it only says that it remained long in any case.

Mixing oils on a different basis

Perhaps the most unresolved problem for car owners is whether motor oils made on a different basis can be mixed. The argument "against", again, is a different set of additives.

The current standards API and ACEA require that the engine oil produced in accordance with them can be mixed with any other certified for the same standards. Thus, if necessary, you can mix even different oil, and do not ruin the engine. The main thing is not to "twist" it in the Red Zone.

Of course, whenever possible, only then the oil is needed into the engine, which is flooded with it. If there is no such possibility, it is preferable to add products to the same brand. As a rule, within the framework of the same lineup, the composition of additives in oils of different viscosity is little different, and on such a mixture it is possible to do up to the planned replacement. It should also be paid to the attention that the same plant can produce oils under different brands.

If you cannot find the product of the same brand, you can add to the engine and any other. The main thing is to avoid high loads and as soon as possible to replace the "spreading" with a lubricant, recommended by the manufacturer of the car.

A little about transmission oils

The problem of mixing oils rises not only when it comes to car engine. Much less often, but still there is a drop in the lubricant level in the gearbox, and a similar question arises about transmission oils. Without going into the theory, you can answer it in the same way as to the one that is set at the beginning of the article: can be mixed with the same conditions as the motor.

Among themselves they have similar composition: the basis plus additives. The mixture obtained after bringing the level to the norm will make it possible to drive several thousand kilometers without prejudice to the gearbox, after which it needs to be merged. Of course, it follows to ride in a gentle mode, avoiding high loads on the gearbox.

The only thing that should not be done categorically - mix motor and transmission oils, as they are intended for different applications, and a rattling mixture, obtained after such manipulations "kill" the engine with a much greater probability than a cocktail of ten varieties of engine oil.
