For years, lubricating greases and motor oils have been manufactured from base oils. Lubricating greases and other automotive oils require different properties in oil and different compositions—the most crucial factor is the viscosity of the liquid at different temperatures. Moreover, the concentration of base oil molecules and how easily they are extracted determine whether the crude oil is suitable to be made into a base oil. The crude oil is heated and (by refining it) the base oil is manufactured. This process makes light hydrocarbons to produce petrol and other fuels, whereas heavy hydrocarbons are used to produce bitumen and base oils.
One widely known base oil is paraffinic crude oil
