Base Oil
Base oil is produced by means of refining crude oil
Base oil is produced by means of refining crude oil. This means that crude oil is heated in order that various distillates can be separated from one another. During the heating process, light and heavy hydrocarbons are separated – the light ones can be refined to make petrol and other fuels, while the heavier ones are suitable for bitumen and base oils.
BASE OIL CHARACTERISTICS
The characteristics of base oils determine their function and reliability. A superior mineral oil requires the best refining processes while the objective of synthetic oil is to achieve properties that are not achievable in mineral oils. Each base oil serves a different purpose, not every function can be ideally served using a single type of base oil.
