Is it possible to mix motor oils

Normal functioning of the internal combustion engine is impossible without quality lubricants . Therefore, replacing the oil is a common routine for every motorist. However, there is still no consensus among motorists about whether motor oils can be mixed. 

There is no clear answer here, but if there is such a need, you should first pay attention to the characteristics of the lubricant. Namely:

• manufacturer;
• The base of the oil;
• viscosity.

Can you mix motor oils: mineral and synthetic

Depending on the base base of oil is:

• mineral;
• semi -synthetic;
• Hydrocking;
• synthetic.

already to this base manufacturers add different additives and thus seek from the liquid the desired characteristics. And it is very difficult to predict all this "chemistry" with each other. Therefore, it is a very risky idea, which is likely to break the car. It is better to pour products with one base into the engine.

What about viscosity?

viscosity (or viscosity) is one of the key parameters of motor oil. If you do not delve into technical details, the mixing of oils of different viscosity is acceptable. But as stated above, it is better to choose a liquid with the same base.

At the same time, keep in mind that when adding a lower class, the viscosity of the mixture in the engine will be reduced. This is also influenced by the proportion of new and old oil. Therefore, you must be sure that the mixture is still suitable for your car.

After reading this information, it may seem that it is quite possible to mix oils of different manufacturers. The main thing is that the base and viscosity coincide. But everything is not so unambiguous.

Can you mix oils of different manufacturers

most often manufacturers of PMM state that their oils cannot be mixed with others.Among motorists is popular that in fact, brands are simply trying to tie more consumers. In addition, in real life it is not always possible to follow this rule.

For example, during the operation of the car it can easily occur when the engine needs to be added urgently, but there is no one at hand. Mixing will not be avoided and if the driver just decided to move to another brand. Even if you completely drain the oil and wash the engine, it will still have the remains of the old liquid.

In fact, these are just recommendations, there are no official prohibitions on brands. The fact is that world manufacturers must adhere to the standards: ACEA for European countries and API for the US.

often oils within one brand are even better compatible than with analogues from other companies. Therefore, in the future, it is still better to make a complete replacement. And you should always strive for the oil in the engine to be as homogeneous as possible.
