The car requires engine oil to operate. Of course, this liquid is sold in all stores. However, due to the wide range of options, it can be difficult to obtain a quality type of engine oil. If you don't want to miscalculate, then get the Elf Evolution 900 SXR 5W-40. This brand has established itself as one of the best types of oil.

 

What is oil for?

The reliability of the engine, its service life and fuel consumption will depend on the quality of this technical fluid. Oil is required to perform the following tasks:

 

lubrication. The oil covers the surface of the parts with a thin layer, which prevents scratches and rapid wear;

corrosion protection. Rust does not appear on the motor elements also due to the coating;

removal of soot, carbon deposits and metal shavings;

heat dissipation, which allows you to maintain a normal temperature of the engine and all its components.

However, the oil can only perform its function with a sufficient level, viscosity and with normal quality. In the event of thickening or evaporation, the liquid can harm automotive components, so it is important to replace it in a timely manner. It is recommended to replace it after 10,000 kilometers. In practice, it is better to do this after seven to eight thousand. If the replacement occurs later, then the next one must be made earlier for the expired mileage. With a delay of more than five thousand kilometers, the wear of automobile components is significantly accelerated.

 

Oil types

The technical fluid is classified according to the viscosity level. There are three types of engine oil:

 

Mineral. A refined product with a very high viscosity. The fluid forms a thick protective layer, which is especially necessary for motors over ten years old. The consumption of such oil is quite large.

Synthetic. Synthetic product with low viscosity. This minimizes oil consumption and protects the engine from overheating.

Semi-synthetic. A mixture of the first two types of oil. Depending on the ratio, the viscosity of the liquid and its other parameters will depend.

Also, the product is subdivided into seasonal and all-season models. In the second case, the liquid can be used in any weather, but the former only at the temperatures indicated by the manufacturer. In no case should you mix different types and types of oils. It is also not recommended to mix oils of different brands, even if they have similar technical characteristics.

 

How to change the oil

Of course, it is better to seek help from specialists. They will do everything professionally and promptly. If necessary, they will conduct an inspection and report any possible malfunctions or problems that should be eliminated. You can also change the oil yourself. The procedure must be done in a clean room using special tools in order to minimize the risk of contamination of the technical fluid and its contact with the parts and interior of the car.

 

Thus, choosing an oil is not that difficult. It is important to follow the manufacturer's recommendations and to replace the technical fluid in a timely manner. This will allow you to increase the life of the engine, and therefore the entire vehicle.
