MOTOR OIL

WHICH MOTOR OIL IS USED?

Manufacturers of engines at the design stage are determined with oil brands depending on operating conditions and design features. After that, resource tests of engines are conducted and recommendations for use are given out. So, before a choice, it is necessary to glance in the instruction on operation, what motor oil is necessary.

Use oil that is recommended by the manufacturer. If you choose oil yourself, for example, before replacing it in the engine, then it is selected according to two main parameters: the quality group and the oil quality class.

OIL SAFETY CLASSIFICATION

The main property of motor oil is its viscosity and its dependence on temperature over a wide range. Here is the standard classification of engine oil for SAE: 10W-40. The first designation “10W” indicates the application temperature, and “40” indicates the viscosity.

CLASSIFICATION OF ENGINE OIL API

Classification of oils according to the conditions of their use and levels of performance properties has been repeatedly supplemented, but the principle of separation of oils into two categories – “S” and “C” is preserved. To the category “S” (Service) are oils for gasoline engines, to the category “C” (Commercial) – oils intended for diesel engines.

Then it remains to choose the brand of motor oil. Here the choice is wide: and domestic oils are comparable with many foreign brands – in fact, at their manufacture, modern base oils and packets of additives are used. The main thing is not to run into a fake and buy in branded stores and gas stations. Or choose oils in tin cans that are difficult to forge.
