Warning! There is an oil pressure warning light on the instrument panel. If it lights up while the engine is running, stop it immediately and find out the reason for the drop in oil pressure.
Motor oil is obtained from the so-called base oil by adding a set of additives and thickeners to it. These additives give the oil certain properties that best suit its purpose, area of application and other indicators.
Based on the type of base oil used, motor oils are divided into three types: mineral (Mineral), synthetic (Fully Synthetic) and semi-synthetic (or more precisely, partially synthetic - Semi Synthetic). The mineral base is the result of oil refining, and the synthetic base is a product of organic synthesis. Synthetic oil is superior to mineral oil in terms of its properties, but it is also significantly more expensive. Semi-synthetic oil has a combined base composition. It is obtained by adding a synthetic composition to a base mineral oil. This ensures an increase in operational properties, in particular, it is possible to expand the temperature range of oil application due to a change in its viscosity. At the same time, the price increases insignificantly.
The scope of application of motor oil may be limited by the engine type: gasoline or diesel. Most of the motor oils produced can be used in both types of engines.
Motor oils are divided into classes according to viscosity and quality level, which determines its basic performance properties.
