by During vehicle movement, motor oil, a comprehensive selection of which can be found at the resource https://oil2go.com.ua/motornye-masla-dlya-legkovykh-avto, must flow unobstructed through the lubrication system’s pipelines, ensuring the ease of movement of the friction pairs of its mechanisms. During the circulation of the working medium, a buffer protective layer is formed between the surfaces of the parts, which exerts a lubricating-cooling effect on all moving units. 
Due to the insufficient thickness or break of the oil film, metal-to-metal contact occurs, leading to accelerated wear, seizure, or damage to the motor’s structural elements. The durability of the lubricating layer under extreme loads depends on the viscosity class of the motor oil. This parameter also determines the applicability of the technical fluid for a specific engine modification operating in a particular mode.
ELF: Guarding the Engine’s Efficiency
Lubricants of the French brand “Elf” are manufactured at modern factory facilities from highly refined base raw materials and a package of active additives, including:
- detergents and dispersants;
- anti-friction and anti-seize additives;
- inhibitors of oxidation processes and corrosion;
- cleaning-dispersing and foam-suppressing agents.
Today, there is a high demand on the automotive market for all-season oils ELF 5W-30, which embody the advantages of narrowly focused products for summer and winter use. It is characterized by performance, thermo-oxidative stability, and applicability in a wide temperature range. Its threshold values range from -30 to +25 °C. 
The above-mentioned features make the viscosity 5W-30 optimal for operation under conditions of seasonal climate fluctuations of temperate latitudes. Properly selected viscosity class helps optimize fuel consumption and extends the life of the power unit as a whole.
