Motor oil: whether it is possible to mix semisynthesis and synthetics

Motor lubricants, depending on the chemical composition are divided into mineral, synthetic and semi-synthetic.

Types of lubricants for car engines

Mineral oils are essentially oil, somewhat purified after its extraction. These oils are quite stable and inexpensive. In addition, cars older than five years will still prefer mineral material.

Synthetic oils are produced in laboratories using special chemical formulas. They are less dependent on external factors, increase the wear resistance of the engine and save fuel consumption.

Semisynthetic oils are produced by the competent combination of previous types of lubricants. They are now the absolute leader in the market.

Each of the types of lubricants has its own circle of admirers. The choice depends mainly on the mileage of the car and the temperature regimes of the environment.

Is it possible to mix semisynthetics and synthetics? After all, there can be different situations on the road, for example, sometimes there is a need to fill up the oil immediately, but the necessary is simply not available.

The combination of different oils: opinions for and against

There are polar points of view of manufacturers and motorists in the question: can I mix different oils? Mixing oils has its own supporters and opponents.

Opponents say that not just invented different types of oils. They have already laid down the correct optimal chemical formula, and its violation will not lead to any positive results.

Followers of the reverse point of view are not so radical and on the question of whether it is possible to mix semisynthetics and synthetics, and also Synthetic and mineral oil, respond positively. This is explained by the fact that semi-synthetic materials are already a product of mixing, more than half of which is made up of a mineral base. And nothing terrible can happen if to this mixture add more synthetic material, purified and processed.

The majority of specialists adhere to a moderate position. And the question about how to change engine oil, whether it is possible to mix synthetics and semisynthetic, you will most likely get a positive answer, but with some reservations.

How to combine the oils correctly?

Not all lubricants are recommended for mixing. It is possible that there will not be any particularly serious negative consequences for the motor, but it is still an extremely undesirable measure, and it will be superfluous to observe certain rules when combining oils, especially if you can choose a more gentle option.

Mixing of oils from different manufacturers

Is it possible to mix synthetic oil and semisynthetic oil from different manufacturers?

Ideally, combine oils better than one brand. This is due to a similar set of additives and a similar chemical formula. Lubricants will not compete with each other accurately and serve well until the next replacement.

So, it is better to use lubricants of the same manufacturer. But because of the lack of choice of oils at hand, the question of whether it is possible to mix synthetics and semisynthetic often occurs, modern manufacturers have found a way out.

Most oil producers today meet the API and ACEA standards, which allow the ability to connect products to each other. Thus, by mixing any lubricants that meet these standards, you can avoid negative consequences when operating your engine, but this is only recommended in an exceptional case.

Oil change taking into account classes of performance properties and viscosity

Is it possible to mix synthetic oil with semisynthetics, if they Different classes and different viscosities?

Manufacturers do not recommend a change in the grade and viscosity of the oil, but if this is not the case, it is preferable to use the same brand as before.

If the class is lower, it is recommended to thoroughly wash all parts of the engine. It is advisable to travel a little in a moderate mode, the bay is a preliminary cleanser.

Consequences of mixing oils

What happens if you mix synthetics and semisynthetics? Choosing quality manufacturers, you can not be afraid of major malfunctions in the engine. If you have purchased oil and are not completely sure about it, it is recommended to conduct an experiment. Mixing the products in small amounts, you can warm them up and follow the chemical reaction. If a precipitate forms or foams occur, these substances can not be combined.

In the absence of an obvious conflict of components, you can safely connect these motor oils. How to mix synthetics and semisynthetic with different viscosities and what will come out as a result?

As mentioned above, lubricants of different viscosities can be mixed, but it is preferable to use one brand. So, if you mix the products, you will get approximately averaged results. Suppose, if we combine in equal proportions the synthetic material 5w-50 and the semi-synthetic 15w-30, the oil 10w-40 will leave.

On the question of whether it is possible to mix semisynthetics and synthetics Different classes of performance properties, was answered above. As a result of this mixing, an oil of lower quality will emerge. Suppose, when mixing the oils of classes H and L, the result is a lower class - H.

Possible negative effects of the connection

Differences in the chemical formula, a different set of additives can conflict with each other in the process of operation. If you even conducted an experiment mixing a small amount of oil, this does not guarantee that as a result of using the mixture there will be no problems.

If you are faced with a problem, can you mix semisynthetics and synthetics, in the absence of other options this can be done, but then it is recommended that you still use the same oil.

As a result of repeated mixing of oil or falling on a fake, or with a large difference in the chemical formula in the engine, deposits and slags can form. This leads to a rapid wear of the motor and to a significant reduction in its service life.

If you take one oil in a fraction of less than 15%, then this will not be dangerous to the engine. This amount of material remains in the car and with a simple replacement of grease.

Mineral oils and the possibility of their connection with other types of oils

Is it possible to mix synthetics and mineral water? This issue is of concern to many motorists who use natural lubricants.

A compound of synthetic products, which is produced on the basis of polyalphaeline (PAO) with mineral oil, is allowed.

Other kinds of synthetic materials combine with mineral ones worse. Therefore, it will be relevant to clarify with the official representatives of the manufacturer or at least the specialists of service centers about the possibility of such mixing.

With less risk, mineral oil can be mixed with semisynthetics.

Conclusion

Synthetics and semisynthetic. Is it possible to mix these oils? The answer to this question is positive, but when connecting it is necessary to remember the basic rules:

• It is better to use oils of the same manufacturer, the same viscosity and grade;
• When changing the class of material, use one product brand, this will reduce the negative consequences for the motor, while the mixture class at the output will be lower;
• At different viscosities of oils, also try to take products of the same brand, the resulting viscosity will depend on the proportions of the materials;
• Extremely rare and undesirable is the transition from one manufacturer to another, before that it is better to consult a specialist;
• Try to take quality products that meet the requirements of American and European quality standards;
• Before using oils, use a cleaner.

Mineral oils can also be mixed with other products, but in most cases this is undesirable.
