Can I mix oils from different manufacturers? Characteristics of engine oils

Virtually all car enthusiasts know that the technical condition of the car depends entirely on the quality of the engine oil and the frequency of its replacement. According to the instructions, every 7-10 km the car needs it. The newly purchased machine is sold with a pre-filled service center with oil, which is recommended by the manufacturer and is ideally suited to the power unit. In this case, the means of one brand in the service station is changed without a preliminary washing, since it is recommended by the vehicle manufacturer and does not cause concern. This scheme is the best for maintaining the "health" of the machine. But in practice, everything looks different.

Whether to mix motor oils with different technical characteristics? Can you mix oil in the engine or not? Will this affect the operation of the motor? Can I mix oils from different manufacturers? Eternal questions, which are constantly disputed motorists.

Some believe that this should not be done, since the washing stage of the motor will be completely excluded. Others assure that there is nothing wrong with this, and this will not affect the operation of the engine in any way.

Both sides are right in their own way. In fact, the oils can be mixed, but with the mind, following certain rules. Otherwise, it is possible to damage the motor, the result will be its repair.

Can I mix different oils? The reasons for this are:

• Forced the need to top up the oil.
• Lack of the desired product brand.

Can I mix oils from different manufacturers? What do specialists think about this?

• Mixing is only allowed for oils of the same category. This is the only way to avoid negative consequences from the ICE.
• Mixing is permissible only if the driver plans to travel not for a long time.

Professionals of this industry unanimously assert that when mixing oils, only problems with additives arise.

The main point of this procedure is the formation of a new chemical composition, the effect of which is impossible to predict.

When mixing oils from different manufacturers, remember that even with thorough removal of oil, some part of the work remains. The result is a connection with fresh lubricant, with which they do not have full compatibility. Many motorists are afraid that such a formula will not allow to ensure 100% of the engine.

Theory of mixing

As mentioned above, the combination of different oils is possible, but only taking into account certain factors that need to be treated with special attention. In order to understand this question in more detail, it is necessary to know what kinds of oils are available.

Synthetic

It is an oil based on artificial chemicals.

Benefits:

• Low volatility;
• Good fluidity at negative temperatures;
• By viscosity, it reacts little to temperature fluctuations;
• High resistance;
• Requires less additives.

Mineral

Its most important component is oil. Some call this species organic.

Benefits:

• Environmentally friendly - the amount of chemicals is minimized.
• Budget value, which is sometimes the decisive factor in the selection.
• Versatility.
• Availability. Available in all auto shops.

Semisynthetic

The name itself says that this is a combination of the first two types of oils.

Benefits:

• Low cost. At a price inferior only to mineral oils.
• Compatible with cars running on any fuel.
• Low volatility.
• Prevents the formation of calcareous deposits.

Admissible combinations of oils:

1. Mineralka with semisynthetics. If a mineral lubricant was previously used in the motor, mixing with semisynthetic is permissible. Also synthetic with the base of polyalphaolefins. Also in mineral oils , the following types of oils can be added: polyester, silicone, glycolic. In this case, it is necessary to take into account such a nuance as the chemical composition of a synthetic product.
2. Synthetics and its mixing. Is it possible to mix oil with other oils when it comes to synthetics? Virtually all of today's commodity producers are developing funds in accordance with European standards. This allows them to be mixed. But it's not a fact that the result will be positive. In some cases, the following troubles may occur: precipitation, foam. They are simply kept to a minimum in comparison with other types of oils. The minimum number of flaws indicates that you have purchased a high-quality product. Before mixing the oils it is necessary to take into account that the first THAT you must carry out the oil recommended by the manufacturer, before flushing the system.
3. Mixing of synthetics and semisynthetic. If at the time of the drop in the oil level in the car you had synthetic resin and only semi-synthetic oils were available, you were saved. Such tools as 5W40 and 10W40, you can mix quietly. This viscosity will range from 6W40 to 8W40. The best option is to combine the existing oil with a better one. In other words, semi-synthetic oils can be diluted with synthetic ones. Mixing of synthetics with semisynthetic is allowed only in critical cases.

4. Production of one commodity producer. According to many experts, it is possible to mix engine oils of the same brand. This statement is true, since oils from one manufacturer have a great similarity in the chemical composition. In other words, they have the same basis, and their chemical composition contains an identical set of additives. Proceeding from this, mixing of oils of one brand is quite admissible. In addition, motorists should know that sometimes there are situations when the same oil is sold under different brands.
5. Oils from different producers. Can I mix oils from different manufacturers? One of the risky mixing options, since no one guarantees 100% efficiency due to different manufacturing processes. But this does not mean that the result will immediately be negative. It happens that when combining such oils, minimal foaming and an imperceptible sediment are observed. Unfortunately, this happens rarely enough.

Mixing of oils 5W30 and 5W40

Oil 5W30 and 5W40 can be mixed. For example, if you have a drastic drop in the fluid level and there is no stock of synthetic 5W40, but there is a similar liquid with a similar label and markings, but from a foreign commodity producer, in this case, your manufacturer's oil 5W30 will help you. When you add this fluid to the engine, there will be no problems with the engine operation. The maximum that can happen is a slight decrease in viscosity. When using the all-weather liquid 5W30 or 5W40, the engine starts at a temperature of 35 degrees. The result of this mixing will be a small change in the coefficient of thermal viscosity. This result is also not critical, since the negative side will be visible only when the engine is running at an overestimate temperature. The driver just has to take care of the car and not overload it.

General mixing recommendations

1. To top up the engine is recommended only that oil, which was filled in it initially.
2. In the case of the possibility of using this type of liquid, products of a similar brand should be used.
3. When buying a product, it is necessary to take into account that one and the same commodity producer is able to produce oils under different brands.

Is it possible to mix oils from different manufacturers in emergency cases? Critical cases involve the use of other types of products. At the same time, it is necessary to minimize the number of loads and correct the situation as soon as possible by replacing it with the recommended oil.

Little tricks about transmission lubricants

It is possible to mix transmission oils or not, we will consider in more detail. This problem occurs only when talking about the engine of the car. This happens rarely, but it happens when the lubricant level in the gearbox is reduced. The answer is quite simple: transmission fluids can be mixed, but only under the conditions specified in motor oils. They should be similar and almost identical in chemical composition. Such a mixture will allow any car enthusiast to safely drive a few thousand kilometers on sparing conditions. After the termination of a way it is necessary to merge a liquid and to replace on recommended by a factory-manufacturer.

It is strictly forbidden to mix motor products and transmission. Ignoring this recommendation will result in loss of engine performance. You have just a murderous mixture to learn.

In any case, to effectively work the engine after mixing the oils will have to return to the manufacturer's recommended oil. Before this, it is necessary to carry out the procedure for washing the engine:

1. Drain the obsolete remedy. Give the car the opportunity to stand a little, so that during this time the oil has merged to the maximum. If possible, tilt the vehicle alternately in both directions. This will drain more liquid.
2. Install a new filter and refill the manufacturer's recommended oil.
3. For three days, try not to overload the machine while the motor gets used to another kind of product.
4. The next procedure for the replacement of oil should occur after 10 thousand km.

The procedure for flushing the motor is over. If you doubt the cleanliness of the engine, shorten the service interval and give the car to the service station.

Consider the characteristics of motor vehicles of different manufacturers.
